REQUIRED MAINTENANCE CONTINUED...
Check and inspect the system in accordance with steps 1 – 7 of semi-annual maintenance
1
instructions.
Disconnect the Systems Releasing Module from the cylinder valve by removing the four screws
2
securing the SRM to the top of the valve and separate. DO NOT lose or damage the Interface
Gasket because it will be required to reconnect the SRM. If the SRM is mounted remotely,
remove all Model BFR-CAP(s), Valve Cap Assembly from each of the cylinder valve(s) by
unscrewing the four mounting screws and remove them from the cylinder valve(s).
Reinstall the Nitrogen Activation Cartridge. To check the satisfactory operation of the fusible link
3
system, cut the terminal link or the “S” Hook attached to the terminal link. This will release
tension on the fusible link line causing the following to occur:
The Systems Releasing Module will operate, causing the detection arm assembly to move
1
back to the left, disengaging the trigger, and allowing the actuation lever to operate. The
actuation pin will puncture the nitrogen cartridge and allow the nitrogen gas to discharge
through the bottom of the SRM or BFR-CAP(s).
The pressurization indicator of each Test Valve Assembly (when used) will be fully extended
2
and there are no leaks in the copper tubing.
The gas valve will close, stopping gas flow to any gas fueled appliances.
3
All auxiliary devices connected to the miniature electrical switch(s) provided in the Systems
4
Releasing Module will have operated.
Remove the used nitrogen cartridge and discard immediately.
4
Replace all fusible link detectors.
5
After testing the fusible link line, repair the terminal link and re-set the control head.
6
Once the Systems Releasing Module is reset, the mechanical pull station must be checked. To
7
do so, pull the handle on the remote pull station and make sure that the following occurs:
The Systems Releasing Module will operate, causing the detection arm assembly to move
1
back to the left, disengaging the trigger, and allowing the actuation lever to operate.
All auxiliary devices connected to the miniature electrical switch(s) provided in the Systems
2
Releasing Module will have operated.
Disconnect the discharge piping from the cylinder valve. Using air or nitrogen, blow out the
8
discharge piping and make sure all the nozzle caps have blown off. If any nozzle cap(s) fails to
blow off during test, carefully examine piping system and nozzle(s) to determine cause and take
appropriate corrective action. Repeat test to assure both piping system and nozzles are
unobstructed.
Reconnect the discharge piping to the cylinder valve and check that all nozzle caps are
9
installed properly.
Reconnect the Systems Releasing Module or Valve Cap Assembly(s) to the appropriate
10
cylinder valve(s) and secure each with the four provided screws.
Before installing the Nitrogen Cartridge it is necessary to make sure that the Actuating Pin is
11
moving freely. Insert the Actuation Pin Resetting Tool into the threaded hole of the Manifold
Mounting Block where the Nitrogen Cartridge is installed.
Install a new Nitrogen Actuation Cartridge by completely screwing the cartridge into the
12
manifold block.
Write the current date on the gray band of a new Nitrogen Actuation Cartridge so that it can be
13
seen in the viewing window of the SRM.
Re-install the Systems Releasing Module cover. Verify that the date on the cartridge is visible in
14
the viewing window.
