• All Installations are to be performed in
  accordance with
• FM-200 Manual
• All appropriate codes and standards
• Local
• State
• Federal
• AHJ (Authority Having Jurisdiction)

4
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.

5
Safety Basics

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

6
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!

7
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.

8
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.

9
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.

General System Design
Modularised approach

• easier system design
• often most economic solution

12
General System Design
Manifolded system

• if containers are positioned remote from the
  hazard
• multi-hazard-system with distribution valves
• higher costs due to larger pipes and longer pipe
  runs

14
Installation
Important!

• Installation drawings must be prepared for the
  hazard.

15
Installation
Important!

• Installation drawings must be prepared for the
  hazard.

16
Container Installation
General

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

17
Container Installation
General
18
Single Container Installation

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

19
Single Container Installation

• The bracket assembly is designed to be mounted to
  a rigid surface with the container assembly
  resting on the floor.

20
Single Container Installation

• Position the container against the back channel
  with the valve outlet pointing left.

21
Single Container Installation

• 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.

22

Multiple Container Installation
Manifold bracket installation

• 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.

26
Pipe Installation
General

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

27
Pipe Installation
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.

33
Pipe Installation
Pipe Hangers

• Hangers must be fixed to a structure capable of
  supporting the pipework.

40
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.

41
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.
