All Installations are to be performed in accordance with: NFPA 2001 Clean Agent Fire Extinguishing System 2000 Edition All Installations are to be performed in accordance with: FM-200 Manual All appropriate codes and standards Local State Federal AHJ (Authority Having Jurisdiction)

Safety Basics All agents may be and must be considered to be hazardous at concentrations above their normal design levels and may be toxic or create dangerous oxygen levels, e.g. may be very dangerous if released into enclosed room, van or shipping container.

Safety Basics Never rush your work! Safety comes before an early finish. Think before you act.

Safety Basics Before installing any pipework from the system container(s), the container(s) must be secured to an immovable object. If this is neglected and the container accidentally discharges the container will become a dangerous projectile! If this happens there could be a serious injury or worst still someone could be killed!

Safety Basics Do not remove plugs or any part whatsoever from a valve unless you know the principle of operation. Never remove plugs from actuation ports until you are immediately ready to fit actuation components. Do not fit actuators until you have verified they are in the reset position.

Safety Basics Never move a container that is not fitted with an anti-recoil device. Never move a container that is not fitted with a valve protection device i.e. transportation cap. The container protection cap protects the valve during transit and MUST be left with the customer upon completion of the installation. Always use a container trolley to avoid possibility of a container falling over or a lifting injury.

Safety Basics Never use undue force to remove transport caps, anti-recoil devices or valve plugs. Never move a container unless an anti-recoil device and transport cap is fitted. Make sure the containers are well secured in the vehicle for transport.  DANGER !

General System Design Modularised approach easier system design Note: A maximum of 9 slave cylinders are allowed to be released by one master cylinder. easier system design often most economic solution

General System Design Manifolded system Note: A maximum of 9 slave cylinders are allowed to be released by one master cylinder. if containers are positioned remote from the hazard multi-hazard-system with distribution valves higher costs due to larger pipes and longer pipe runs

Installation Important! Installation drawings must be prepared for the hazard. enclosure volumes / agent quantities container data scaled pipe network plan + pipe network isometric pipe diameters, pipe length, drops & rises nozzle data solenoid actuator technical data wiring charts (low pressure switch, pressure switch, actuator) fittings data Installation drawings contain the following information:

Installation Important! Installation drawings must be prepared for the hazard. These drawings should be followed closely in order to ensure that the system meets its design criteria. If for any reason modifications are required the system must be recalculated before proceeding with the installation.

Container Installation General: Container location is identified on the system drawings Containers must be firmly secured to a wall or bulkhead

Container Installation General: No safety outlet and actuation caps should be removed at this stage!

Single Container Installation Fix the back channels of the mounting brackets to the wall at the appropriate hights using suitable anchor type bolts.

Single Container Installation The bracket assembly is designed to be mounted to a rigid surface with the container assembly resting on the floor. Each strap is notched for insertion into the back channel allowing the container to be properly aligned.

Single Container Installation Position the container against the back channel with the valve outlet pointing left. Insert the container straps at top and bottom and secure with the bolts provided.

Single Container Installation Remove the safety outlet cap from the valve outlet adapter With the cap removed from the valve outlet adapter, install a union coupling. Caution. Do not over tighten the container connection. Excessive tightening may cause the valve outlet thread to be damaged. Remove the union and replace the safety outlet cap after the initial pipe run has been installed.

Multiple Container Installation Fix the back channels of the mounting brackets to the wall at the appropriate hights using suitable anchor type bolts.

Multiple Container Installation Position the containers against the back channel with the valve outlet pointing left at the required spacing for the manifold ports.

Multiple Container Installation Manifold bracket installation: cantilever bracket manifold bracket vertical back channel

Multiple Container Installation Manifold bracket installation: Fix the vertical back channels to the wall (appropriate height see table) Locate and secure the cantilever brackets to each channel For safety remove discharge hose and replace safety caps while pipework is installed. Locate manifold brackets in cantilever channel Remove outlet safety cap and attach discharge hose between valve and manifold. Adjust cantilever height as required and secure in position. Hygood manual page 47

Pipe Installation General: The installation should commence at the union elbow (single container) / manifold assembly (multiple containers) and progress along to the discharge nozzles.

Pipe Installation General: Section 5 General: Install the pipework acc. to the installation drawings provided ensuring that the following is adhered to: The piping material must conform to the requirements of BS5306: Part 5 Section 5.1. / NFPA 2001 2-2. The pipe must be reamed, blown clear and swabbed with an appropriate solvent to remove mill varnish and cutting oil before assembly (required by BS / NFPA). PTFE tape is the only acceptable pipe sealant and must be applied to the male threads.

Pipe Installation Pressure test of pipe work depends on standard / local regulation. All open ended pipe shall be pneumatically tested in a closed circuit for a period of 10 minutes at 3 bar. At the end of the 10 minute period the pressure drop shall not exceed 20% of the test pressure i.e. 2.4 bar.

Pipe Installation Pipe Hangers: Hangers must be spaced according to the size of the pipe. Hangers must be fixed to a structure capable of supporting the pipework.

Pipe Installation Pipe Hangers: Hangers must be placed within 300 mm (12") of the discharge nozzle. Hangers must be placed between elbows that are more than 600 mm (24") apart.

Nozzles All nozzles require the installation of a dirt trap comprising 1 side tee, 2 nipples and 1 pipe cap. Fit the nozzle to the nipple of the dirt trap and check the nozzle orifice to ensure proper orientation. maximum

Nozzles A false ceiling comprising loose tiles must have the tiles retained within a 2 m radius of the nozzle to prevent moving during discharge. max. 300 mm Nozzles should be installed a maximum of 300 mm below the ceiling.
