LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA 72 and NFPA 101 Supervised Automatic Sprinkler System Overview Look at the requirements that mandates these systems Understand how to find these requirements in the codes Explain how these requirements affect your fire alarm designs Outline what needs to be provided for code compliance Detail how to submit these systems for plan review

“How does the sprinkler system affect my fire alarm system design?”
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY “What is the difference between an approved automatic sprinkler system and approved supervised automatic sprinkler system?” “How does the sprinkler system affect my fire alarm system design?” “How do I know that the sprinkler is required to be supervised?” “Is it acceptable to chain open the main supply valve as prescribed in NFPA 13 and meet the intent of a supervised system?” “If my fire alarm system is connected to the building sprinkler system, is it then automatically required to transmit off site to a monitoring facility?”

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code * Supervisory Signals. Where supervised automatic sprinkler systems are required by another section of this Code, supervisory attachments shall be installed and monitored for integrity in accordance with NFPA 72, National Fire Alarm Code, and a distinctive supervisory signal shall be provided to indicate a condition that would impair the satisfactory operation of the sprinkler system. Monitoring shall include, but shall not be limited to, monitoring of control valves, fire pump power supplies and running conditions, water tank levels and temperatures, tank pressure, and air pressure on dry-pipe valves. Supervisory signals shall sound and shall be displayed either at a location within the protected building that is constantly attended by qualified personnel or at an approved, remotely located receiving facility. (Note: This office’s interpretation of “constantly attended location” is 24 hours a day, 7 days a week and 365 days a year.)

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Alarm Signal Transmission. Where supervision of automatic sprinkler systems is provided in accordance with another provision of this Code, waterflow alarms shall be transmitted to an approved, proprietary alarm receiving facility, a remote station, a central station, or the fire department. Such connection shall be in accordance with (Therefore based on this requirement the proposed fire alarm system cannot be a local system!)

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Mandates for supervised automatic sprinkler systems are rarely in the _.3.5 Extinguishing Requirements in occupancy chapters in the Life Safety Code. These requirements are typically given as a code trade-off to extend travel distances, dead-end corridors, or common path of travel. These requirements sometimes are stipulated in minimum construction type limitations in specific occupancy chapters.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY “Does this mean that I am going to have to look at other sections of the code, other than fire alarm section, to verify that my fire alarm design is code compliant?” Absolutely! The 2000 edition of the Life Safety Code has changed a majority of the sprinkler requirements and sprinkler exceptions to include the term “supervised”. You need to be “code savvy.” Understand other requirements that would mandate a “supervised automatic sprinkler system” - this will affect the design of your fire alarm system.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code There are requirements in the “core chapters” (Chapters 1- 11) Areas of Refuge. General. An area of refuge used as part of a required accessible means of egress in accordance with 7.5.4, or used as a part of any required means of egress, shall conform to the following: (1) The general requirements of Section 7.1 (2) The requirements of and Exception: The requirement of (2) shall not apply to areas of refuge consisting of stories of buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code There are requirements in the “core chapters” (Chapters 1- 11) * Where two exits or exit access doors are required, they shall be placed at a distance from one another not less than one-half the length of the maximum overall diagonal dimension of the building or area to be served, measured in a straight line between the nearest edge of the exit doors or exit access doors. Where exit enclosures are provided as the required exits and are interconnected by not less than a 1-hour fire resistance-rated corridor, exit separation shall be permitted to be measured along the line of travel within the corridor. Where more than two exits or exit access doors are required, at least two of the required exits or exit access doors shall be arranged to comply with the minimum separation distance requirement. The other exits or exit access doors shall be located so that if one becomes blocked, the others shall be available. Exception No. 1: In buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7, the minimum separation distance between two exits or exit access doors measured in accordance with shall be not less than one-third the length of the maximum overall diagonal dimension of the building or area to be served.

NFPA 101 - Life Safety Code Chapter 16 - New Day Care Occupancy
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy No dead-end corridor shall exceed 20 ft (6.1 m), other than in buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7, in which case dead-end corridors shall not exceed 50 ft (15 m). No common path of travel shall exceed 75 ft (23 m), other than for the first 100 ft (30 m) in a building protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy Travel distance shall meet the following criteria: (1) The travel distance between any room door intended as an exit access and an exit shall not exceed 100 ft (30 m). (2) The travel distance between any point in a room and an exit shall not exceed 150 ft (45 m). (3) The travel distance between any point in a sleeping room and an exit access door in that room shall not exceed 50 ft (15 m). Exception: The travel distance in (1) and (2) shall be permitted to be increased by 50 ft (15 m) in buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy Windows for Rescue. Every room or space normally subject to client occupancy, other than bathrooms, shall have not less than one outside window for emergency rescue that complies with the following: (1) Such windows shall be openable from the inside without the use of tools and shall provide a clear opening of not less than 20 in.

Exception No. 1: This requirement shall not apply to buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy Corridors. Every interior corridor shall be constructed of walls having not less than a 1-hour fire resistance rating in accordance with Exception No. 2: In buildings protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7, corridor walls shall not be required to be rated, provided that such walls form smoke partitions in accordance with “What about Detection, Alarm, and Communications Systems or Extinguishment Requirements?”

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy Detection, Alarm, and Communications Systems. General. Day-care occupancies, other than day-care occupancies housed in one room, shall be provided with a fire alarm system in accordance with Section 9.6. Initiation. Initiation of the required fire alarm system shall be by manual means and by operation of any required smoke detectors and required sprinkler systems. (See ) Occupant Notification. Occupant notification shall be in accordance with Positive alarm sequence shall be permitted in accordance with Emergency Forces Notification. Fire department notification shall be accomplished in accordance with Detection. A smoke detection system in accordance with Section 9.6 shall be installed in day-care occupancies, other than those housed in one room. Detectors shall be installed on each story in front of the doors to the stairways and in the corridors of all floors occupied by the day-care occupancy. Detectors also shall be installed in lounges, recreation areas, and sleeping rooms in the day-care occupancy.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY NFPA Life Safety Code Chapter 16 - New Day Care Occupancy Extinguishment Requirements. Any required sprinkler systems shall be in accordance with Section 9.7. Neither of these sections require the automatic sprinkler system to be supervised - this is an example of why you need to have a better understanding of the codes as a whole! Code Savvy!

Waterflow & tamper devices
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY What if the building is not required to have a fire alarm system in accordance with the _.3.4 section of the occupancy chapter, but the building owner wishes to utilize a supervised automatic sprinkler system to enhance an architectural feature, what would be the minimum equipment to satisfy this requirement? The State Fire Marshal’s Office views these “supervised automatic sprinkler systems” as required fire alarm systems not providing occupant notification at the protected premise. Therefore, the following equipment would be required: Control Panel - Listed for the appropriate signaling system type, sprinkler supervision and waterflow. Manual pull station - See 101: , required when the sprinkler system is down due to maintenance. Waterflow & tamper devices Smoke detector - See 72:1-5.6, required if the control panel is not located in a continuous occupied area. These systems can be submitted on the Fire Alarm Exemption Request Form pursuant to State Fire Marshal Memorandum 99-2.

“How does the sprinkler system affect my fire alarm system design?”
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY “What is the difference between an approved automatic sprinkler system and approved supervised automatic sprinkler system?” Supervised sprinkler systems are monitored for integrity by the fire alarm control panel, which transmit signals (supervisory, trouble and alarm) to a monitoring facility. “How does the sprinkler system affect my fire alarm system design?” The supervisory requirements of NFPA 101 would prohibit the fire alarm signaling system type to be a protected premises or local. “How do I know that the sprinkler is required to be supervised?” Get a copy of the architectural review or ask the design professional.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY “Is it acceptable to chain open the main supply valve as prescribed in NFPA 13 and meet the intent of a supervised system?” No! The requirements of 101: stipulates that the where a supervised automatic sprinkler system is required by another section of the code, the supervisory attachments shall be installed and monitored in accordance with NFPA 72. “If my fire alarm system is connected to the building sprinkler system, is it then automatically required to transmit off site to a monitoring facility?” No! Only if other sections of the code require the sprinkler system to be supervised.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Louisiana Automatic Fire Alarm Western Region Meeting Lafayette 9/28/01 Questions and Answers

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 1. NFPA (2000) exception no. 1 states areas not subject to occupancy by persons who are hearing impaired shall not be required to comply with the provisions for visible signals. A. Does this mean strobes would only be required in the Lobby/Public Restrooms of a business occupancy, if none of the employees were hearing impaired? No. When a fire alarm system is required by the 101 Life Safety Code occupancy chapter, the alarm system notification is required to be accessible (audible and visual). ADAAG Section states that at a minimum, visual signal appliances shall be provided in buildings and facilities in each of the following areas: restrooms and any other general usage areas (e.g., meeting rooms), hallways, lobbies, and any other area for common use. Common use spaces are defined as spaces used by employees for common use (such as copy and file rooms) and as spaces used by the public for common use. The ADA requires accessible facilitation in anticipation of the hiring of disabled persons to prevent discrimination.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY B. If the business has a hearing impaired employee, is only their work area required to have visual notification, or would the complete building? When a fire alarm system is required by the 101 Life Safety Code occupancy chapter, the alarm system notification is required to be accessible (audible and visual) in all common use spaces throughout the building regardless of whether or not hearing impaired individuals are employed. Title I of the ADA addresses the requirements of accommodation for disabled individuals within individual workspaces.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY C. Does the fact that the system is non-required have any bearing on questions above? Yes, visual notification is not required when the system is a non-required system. If the fire alarm is a non-required system, the Fire Marshals Office requires only that the Professional of Record or the Owner of the facility file a Non-Required Fire Alarm System Request for Exemption form with this office.

No. Please read further in the section:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 2. In reading requirements of for assembly occupancies (more than 300), I am confused with wording of It states occupant notification shall be by means of voice announcements, either live or pre-recorded, initiated by the person in the constantly attended location. A.Does this mean automatic voice announcements are not permitted? No. Please read further in the section: Where the authority having jurisdiction determines that a constantly attended location is impractical, a fire alarm system in accordance with Section 9.6 shall be used that meets the following criteria: (1) It shall be initiated by manual fire alarm boxes in accordance with (1) or other approved means. (2) It shall automatically provide prerecorded evacuation instructions in accordance with

No. 101:13.3.4.3.4(2) specifically refers to 101:9.6.3.10.
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY B. Doesn’t this conflict with “automatically transmitted or live voice evacuation” to occupants shall be permitted and shall be in accordance with NFPA 72? No. 101: (2) specifically refers to 101:

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 3. We talk often about the IRS tax code being overly complex and not understood by their own employees. I would venture to say the same about NFPA 101 and 72. Personally, I feel there are too many back and forth references, between chapters of NFPA 72 and 101 concerning requirements and exceptions. It is clear to me that the Sprinkler Industry has garnered numerous exceptions, that would be equally served by an equivalent exception for an automatic fire alarm system, especially in areas covering exiting requirements. A. Why is it assumed that installation of a “supervised sprinkler system” can be equivalent to enclosed escape routes ( exception no. 5)? I am of the understanding your reviewer would not give equivalency to use of an automatic detection system with off-premise monitoring. (This was an existing historic structure, being converted to a small museum building. Sprinklers operate at 165oF, at which time the building would be filled with smoke.)

NFPA 101:38:2.4.2 Exception No. 5 states the following:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Personally, I would much rather be notified by an early warning smoke detection system. Can you explain why the Life Safety Code and the AHJ community feels a sprinkler system in this situation is better life safety than a fire detection system with early warning smoke detectors? NFPA 101:38:2.4.2 Exception No. 5 states the following: “A single exit shall be permitted for a maximum two-story, single-tenant space/building protected throughout by an approved, supervised automatic sprinkler system in accordance with Section 9.7 where the total travel to the outside does not exceed 100 feet.” Exception No. 5 provides some relief from the requirement that mandates two separate exits on every story. The exception offers any single-tenant space in a supervised, automatic sprinklered building with a maximum of two stories the option of providing only one exit if the total travel distance to the outside does not exceed 100 feet.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Automatic sprinkler systems remain the single most effective means of controlling fire spread for the widest range of buildings and areas. It is for this reason that the Code contains numerous exceptions to requirements based on the equivalency of a supervised automatic sprinkler system. This equivalency has been acknowledged through historic fire data, with and without sprinklered building cases. Initially, when a project is submitted to this office for plan review, our office cites deficiencies based on requirements of the codes adopted by the state legislature. The initial plan review will allow equivalencies and exceptions only as specifically published in the code. Any proposed equivalencies shall be made by the P.O.R. or the building owner. Such proposals shall be submitted with an Equivalency Appeal Request Form and $100 review fee. If this office determines that the equivalency presented meets or exceeds the code, then a letter will be published granting the equivalency.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 4. State Fire Marshal rules and regulations allow for delegation of inspection duties to other entities, i.e., City of New Orleans, Baton Rouge Fire Prevention. Can you elaborate on exactly which of your offices duties are delegated, and whether or not these agencies are supposed to furnish inspection of completion projects, in the same manner and professionalism of your office? In accordance with R.S. 40:1563.1(C) Certified Fire Prevention Bureaus are responsibly for conducting fire inspections within their local jurisdiction except for facilities requiring State or Federal Licensure. Facilities requiring State or Federal Licensure are listed below by occupancy type: Health Care (hospital, nursing homes, Limited Care, ambulatory health care, residential board & care), day care centers, group homes/residential board&care, physical therapy, universities/colleges, state owned, state leased, detention, child family day care home.

1) All inspections except Licensed Facilities:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY In addition to the previous slide, upon request from the Certified Fire Prevention Bureau the State Fire Marshal's Office will conduct inspections in the following occupancies: Final Inspections( all types of occupancies), annual inspections of existing schools. Listed below are the Certified Fire Prevention Bureaus and the type of inspections conducted for the State Fire Marshal Office: 1) All inspections except Licensed Facilities: Alexandria F.P/ Baton Rough F.P/ Bossier City F.P/Central F.P. Dist. #4 in B.R./Lafayette F.P/Lake Charles F.P/Monroe F.P/Pineville F.P/ Shreveport F.P/ St. Tammany F.P. Dist. #1/ West Monroe F.P 2) All inspections except Licensed Facilities and Final Inspections (all types of occupancies*) Bayou Cane F.P/ Harvey F.P Dist.#2/Jefferson Parish F.P-East Bank Consolidated Dist./ Kenner F.P/ New Iberia F.P./St. Geoge F.P.Dist. in EBR Parish/ *When a Final Inspection is completed Certified Fire Prevention Bureaus conduct annual inspections except in Licensed Facilities. 3) All other Certified Fire Prevention Bureaus not listed above conduct annual inspections in existing buildings except in Licensed Facilities and schools. Beginning July 1, 2001, F.P. Bureaus who conduct F.I. for the Fire Marshal are suppose to submit the reports to this office. Also, they are suppose to inspect in accordance with the codes enforced by the SFM Office, however if the local F.P. Bureau has a more stricter code requirement then they can enforce the stricter requirements.

Sure! Anything to make y’all code savvy!
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 5.Would your office be willing to work with this Association to develop a matrix of NFPA 101 fire alarm system requirements for various occupancies? It seems that this would help to indicate the general requirements for fire alarm systems, of course subject to final submittal of the specific system to your office for review. Sure! Anything to make y’all code savvy!

3.3.134.8.2* Occupancy, Industrial, High Hazard.
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 6. Reference Please define High Hazard Industrial Occupancy, operation or process. * Occupancy, Industrial, High Hazard. An industrial occupancy in which industrial operations that include high hazard materials, processes, or contents are conducted. A Occupancy, Industrial, High Hazard. A high hazard occupancy includes occupancies where gasoline and other flammable liquids are handled, used, or stored under such conditions that involve possible release of flammable vapors; where grain dust, wood flour or plastic dusts, aluminum or magnesium dust, or other explosive dusts are produced; where hazardous chemicals or explosives are manufactured, stored, or handled; where cotton or other combustible fibers are processed or handled under conditions that might produce flammable flyings; and where other situations of similar hazard exist. Chapter 40 and Chapter 42 include detailed provisions on high hazard occupancy.

Yes. Please refer to 101:6.1 Classification of Occupancy:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY A) Are there any clear-cut indicators your office uses to determine if an occupancy is a Business Occupancy or an Industrial Occupancy? I see many projects where the Architectural submittal is done as a Business Occupancy, when I feel they are really Industrial Occupancies. Most fire alarm companies will usually follow with using the caption off of the Architectural Plan Review letter. As you know, there is a lot of difference in requirements for fire alarm systems between 39:3.4.1 and 40:3.4.1. Yes. Please refer to 101:6.1 Classification of Occupancy: * Definition — Business Occupancy. An occupancy used for account and record keeping or the transaction of business other than mercantile.

Business occupancies include the following:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY A Business Occupancy. Business occupancies include the following: (1) Air traffic control towers (ATCTs) (2) City halls (3) College and university instructional buildings, classrooms under 50 persons, and instructional laboratories (4) Courthouses (5) Dentists’ offices (6) Doctors’ offices (7) General offices (8) Outpatient clinics, ambulatory (9) Town halls Doctors’ and dentists’ offices are included, unless of such character as to be classified as ambulatory health care occupancies as defined in

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Birth centers occupied by fewer than four patients, not including infants, at any one time; not providing sleeping facilities for four or more occupants; and not providing treatment procedures that render four or more patients, not including infants, incapable of self-preservation at any one time should be classified as business occupancies. For birth centers occupied by patients not meeting these parameters, see Chapter 18 or Chapter 19, as appropriate. Service facilities common to city office buildings such as newsstands, lunch counters serving fewer than 50 persons, barber shops, and beauty parlors are included in the business occupancy group. City halls, town halls, and court houses are included in this occupancy group insofar as their principal function is the transaction of public business and the keeping of books and records. Insofar as they are used for assembly purposes, they are classified as assembly occupancies.

6.1.12.1* Definition — Industrial Occupancy.
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY * Definition — Industrial Occupancy. An occupancy in which products are manufactured or in which processing, assembling, mixing, packaging, finishing, decorating, or repair operations are conducted. A Industrial Occupancy. Industrial occupancies include the following: (1) Dry cleaning plants (2) Factories of all kinds (3) Food processing plants (4) Gas plants (5) Hangars (for servicing/maintenance) (6) Laundries (7) Power plants (8) Pumping stations (9) Refineries (10) Sawmills (11) Telephone exchanges

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY In evaluating the appropriate classification of laboratories, the authority having jurisdiction should treat each case individually based on the extent and nature of the associated hazards. Some laboratories are classified as occupancies other than industrial; for example, a physical therapy laboratory or a computer laboratory.

Please refer to the answer to the first part of this question.
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY B) Paragraph 40:3.2 states every High Hazard Industrial Occupancy, operation, or process shall have approved supervised automatic extinguishing system per Section 9.7 and shall operate per paragraph 40: to automatically initiate an occupant evacuation signal. Can you furnish guidelines for what your office deems “High Hazard Industrial Occupancy” in accordance with paragraph 40:1.4.1(c)? Please refer to the answer to the first part of this question.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 7. During the Final Inspection for a project we were recently involved in, the State Fire Marshal Deputy required that the system smoke detectors be installed adjacent to remote annunciators and remote power supplies. A review of NFPA 72:1-5.6 only requires these detectors for protection of control equipment in areas which are not continuously occupied. NFPA 72 defines a control unit as a system component that monitors inputs and controls outputs through various types of circuits. Based on a memo from Jerry Jones dated August 5, 1998, he agrees and states that remote power supplies and remote input/output devices do not require protection with automatic smoke detectors. The fire alarm contractor installed the additional six (6) detectors at a cost of approximately two thousand, five hundred dollars, ($ ) to the owner so that the deputy would not reject him upon re-inspection. The deputy was advised of the referenced memo but was adamant that it did not apply. Please clarify exactly what equipment requires protection by smoke detectors.

It is NOT the intent of this citation to include the following:
LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Pursuant to the letter addressed to this association which originally referenced the 1996 edition of NFPA 72 - National Fire Alarm Code, Section Protection of Control Equipment, defined control equipment as “A system component that monitors inputs and controls outputs through various types of circuits.” This office policy specifically requires a smoke detector to protect a fire alarm control panel if it is not located in a continuously occupied area. It is NOT the intent of this citation to include the following: Booster Panels Annuciator Panels Externally Mounted DACTs Cabinets Storing Secondary Power Supply Transponder Panels Anything else in a red or beige metallic box that isn’t a fire alarm control panel! Mrs. Felicia Cooper, State Fire Marshal Administrator shall be made aware of this problem.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 8. Currently, the exemption request applications as well as the complete submittal application do not require a signature from the N.I.C.E.T. Level III licensed employee when submitted. We have had a situation occur where a company without a license sent in an exemption request with our company information and license number. We fortunately became aware of it and reported it to your office. We believe that all applications should require a signature. Signature of applicant may not relieve this problem. A signature will not prevent an applicant from listing falsified information on the exemption request form. A determination from this office concerning the exemption request will always be mailed to the address of the company listed on the request form. This agency attempts to verify the correct mailing address for the company. If this office’s determination is received by a company for a project which is not to be performed by that company, prompt notification should be made to this office for proper action.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY 9. When a professional of record completes plans for a tenant finish out or a small project that he assumes will add ten devices or less to an existing system and marks them on his plans in that manner. What do we do as fire alarm contractors when we know that the requirements will be greater than ten but the professional of record, general contractor, or electrical contractor instructs us to send the exemption request in anyway? If we send the exemption request to your office your personnel will assume that the project only needs the devices we put on the exemption request form since there is not a set of plans attached. This now is left into the state or local fire marshals hands that inspects the project. The general contractor will show him an approved exemption request form and explain your office approved the project addition. Call one of the Architectural Supervisors or the Staff Fire Alarm Specialist and we will handle these situations on a case by case basis. We will try to work with you within reason.

If an existing building (in this case a school) that already has a Fire Alarm System is adding a new wing that will require the addition of more than 10 devices, will the existing section of the building be required to be brought up to current code? If the addition of the school exceeds 50% of the estimated value of the existing building, then the entire school would be required to be brought up to current code requirements.

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY A) If the existing Fire Alarm System does not have the capacity to handle the new devices and the FACP has to be replaced, also requiring existing smoke detectors to be replaced (for compatibility), would the existing section of the building then be required to be brought up to current code? If the addition of the school exceeds 50% of the estimated value of the existing building, then the entire school would be required to be brought up to current code requirements. The replaced smoke detectors would be required to comply with the code enforced at the time of original installation, be sure the owner or P.O.R. provides that documentation with the submittal.

(Recognizing that the cable must be protected to 7 feet above finished floor) Will the remote control equipment need to be within a 2-hour area provided the connected cable assembly meets the 2-hour rating? Must the 2-hour space be dedicated to the fire alarm system or can it be co-located with other electrical, telephone or data cabling? Is it acceptable to install remote system nodes and or power supplies in an approved stairwell provided that the equipment is dedicated to fire alarm service?

LOUISIANA DEPARTMENT OF PUBLIC SAFETY AND CORRECTIONS OFFICE OF STATE FIRE MARSHAL, CODE ENFORCEMENT AND BUILDING SAFETY Survivability - Notification Appliance Circuitry and Fire Command Center Is a central control station (fire command station) always required in a high rise building? 72:3‑ (99 edition) states that survivability requirements are applicable to notification appliance circuits and any other circuits necessary for the operation of the notification appliance circuitry.
