Low-Voltage 101 Plus more…
Text box Common Terms Tossed Around CM, CMR, CMP, CMX FPL, FPLR, FPLP Riser-Rated and Plenum CL2 and CL3 UL Listed AWG and Conductors CCA, CCS, and BC Reel, Reel-in-box (RIB), Spool Shielded or Unshielded Solid or Stranded Cat5e, CAT6, RG6, and others
Text box Cable Ratings? CM – A general purpose Communications cable rating. Complies with UL CMR – CM cable rating with valuable extras built in. Complies with UL-1666 CMP – Includes traits of the CM and CMR cable ratings plus the ability to run inside air plenums and ducts. Complies with NFPA-262 and UL-910. CMX – Basically the same as the CM rating with the exception of being UV rated. Complies with UL FPL – A general purpose Fire Alarm cable rating. Complies with UL-1424 and UL FPLR – Similar to CMR Communications cable rating but for use with Fire Alarm systems. Complies with UL-1424 and UL FPLP – Shares the same traits as CMP Communications cable rating. Complies with UL-1424 and UL-910
Text box Riser-Rated (CMR) vs. Plenum (CMP) Riser-Rated: Cable that can be ran between floors and not in duct work Plenum: Cable that can be ran through plenum spaces of buildings.
Text box Non-Plenum Airspace
Text box Plenum Airspace
Text box CL2 vs CL3 CL2 (Class 2 Circuit wire): Rated for up to 150 volts. CL3 (Class 3 Circuit wire): Rated for up to 300 volts. Both are types of multi-purpose wire used for security systems, speaker wire, intercom systems, and more.
Text box Who or what is UL? UL is short for Underwriters Laboratories Testing and approving products for safety since service centers in 70 countries Performs safety testing on 18,750 categories of electrical, mechanical, and chemical products
Text box ETL – Extraterrestrial Life??? ETL – Electrical Testing Laboratory ETL is a product certification organization with more than 80,000 listings The ETL Listed Mark is proof of product compliance to North American safety standards The ETL Verified Mark is a symbol of performance integrity ETL provides a competitive advantage in the marketplace
Text box AWG? What? Huh? AWG: American Wire Gauge Wire gauge describes the conductor diameter Small AWG numbers = larger wire diameters Large AWG numbers = smaller wire diameters Conductors? Train? Orchestra? Simply, anything that allows current to flow through it. In a wire and cable setting, the conductor is the copper part of the wire. The conductor is always insulated to prevent electrical shock
Text box Copper Conductor Types BC (Bare Copper): All conductors are 100% copper (Also referred to as Solid Copper) CCA (Copper Clad Aluminum): Core is composed of aluminum and outer is copper. CCS (Copper Clad Steel): Core is composed of steel and outer is copper.
Text box Reel, Spool, and Reel-in-Box Reel or Spool: Round drum-shaped object used to carry various types of cable. Typically constructed out of wood, plastic, or aluminum. Reel-in-Box (RIB): Same concept as the standard reel or spool except this has a set of stands inside the box to support the reel. The box also makes for easier carrying and loading than a regular reel or spool. The stands and reel are typically made out of plastic.
Text box To shield or not to shield… Shielded Cable Shielded - braided strands of copper (or other metal, such as aluminum) or a thin layer of aluminum foil. Applications - security systems provides some protection from power frequency and radio frequency interference, reducing the number of false alarms being generated. Coax cable uses braided strands of copper for shielding. Abbreviations – F/UTP: Foiled Twisted Pair U/FTP: Shielded Twisted Pair Unshielded Cable Unshielded – provides no shielding or protection from interference. Applications – unshielded cable can be used for any application when electrical interference isnt a concern. Abbreviations – U/UTP: Unshielded Twisted Pair
Solid or Stranded Solid Core Cable Solid core cable uses one solid wire per conductor Examples: CAT5e, CAT6, Fire Alarm Cable, Thermostat Cable, and High Voltage Electric Cables Stranded Cable Stranded conductor uses multiple wires wrapped around each other in each conductor Examples: CAT5e and CAT6 patch cords, Security Alarm Cable, and Speaker Cable
Text box Wide, Wide World of Cable Types Cat5e Cat6 RG6 Security Alarm Cable Fire Alarm Cable Thermostat Cable Speaker Cable Siamese CCTV Cable
Text box Cat5e Cable Frequency: Up to 100MHz Maximum cable length: 328 ft (100 m) Standard AWG: Conductor: Solid copper Industry standard for networking and communications
Text box Cat6 Cable Frequency: Up to 250MHz Maximum cable length: 328 ft (100m) Standard AWG: Conductor: Solid copper Built in separator to reduce interference Improved networking abilities over Cat5e.
Text box RG6 Coaxial Cable Recommended for distributing signals from cable TV, satellite dish or from a roof-top antenna Most common types of Coaxial cable include: RG59, RG6 Dual and RG6 Quad Shield
Text box Security Alarm Cables Provides connection between security system components i.e., keypads, door contacts, motion detectors, sirens, etc. Typically the conductors are stranded The most common security cables are: 18AWG/2 conductor, 22AWG/2 conductor, 22AWG/4 conductor, 22AWG/6 conductor
Text box Fire Alarm Cables Provides connection for fire alarm control panels and fire devices i.e., pull-stations, strobes, sirens, smoke detectors, etc. Conductors are always solid core The most common fire alarm cables are: 18AWG/2 conductor, 18AWG/4 conductor, 16AWG/2 conductor, 16AWG/4 conductor
Text box Thermostat Cables Cables designed for residential and commercial heating and cooling controls. Typically 18AWG or 20AWG Multiple solid core conductors (2-12 conductors)
Text box Speaker Cables Provides connection between speakers and audio amplifiers Typically 2 or more stranded conductors 16AWG wire is most common
Text box Siamese Cable Cable designed to connect cameras to recording devices Constructed out of 1 RG59 Coaxial Cable and 1 18AWG/2 stranded conductor cable Convenient cable for camera installations.
