Firestat Test Procedure
NOTE: The following should be tested with battery power only (A/C power disconnected) and then tested
with A/C power connected.
ATTENTION: You do not need nitrogen for this test.
CAUTION!: The use of a torch or flame is strictly prohibited.
Figure 56 - Firestat Riser Location
Use a portable heat source to apply heat to the duct Firestat in accor-
dance with the manufacturer’s instructions. Please refer to applicable
detector manufacturer’s manual. Refer to Figure 56.
When the Firestat’s heat set point is reached, the fire system will acti-
vate. Some residual nitrogen from the test cylinder may release.
- When performing this test with battery power only, check the CORE-
board fire status light.
- When performing this test with A/C power, the exhaust fan will acti-
vate. Depending on the hood lights activation setting, they will turn
on or off.
Check all Firestats in the system.
After the system is tested, install nozzle caps, and install hood filters.
Disconnecting Service Cylinder Tank
Place the TANK fire system into “Test” mode.
Relieve pressure from the Nitrogen Cylinder.
• Cylinder assemblies with one Schrader valve:
- Slowly disconnect the inline filter from the PAK hose.
• Cylinder assemblies with dual Schrader valves:
- Check all cylinder gauges to confirm proper pressure is within the “green” range. If pressure is low, refer
to “Adding Nitrogen to Tank(s)” on page 68.
- Slowly disconnect the test hose with inline filter from the tank cylinder.
Relieve pressure in the actuation line. Slowly disconnect the test hose from the PAK service valve.
Disconnect the test hose from the fire system distribution piping service port. Remove low-loss fitting adapter.
Re-arming System
Reset each PAK and any SVAs by pushing the spring-loaded pin on the piston. Press the piston into the body
of the actuator.
Verify residual pressure is relieved at Schrader valve.
NOTE: If a PAK/SVA fails to operate or cannot be properly reset, the unit must be replaced. Refer to
page 67 for replacement procedures.
Verify all of the actuation lines between the PAK and SVA(s) are secure and tight. Place Schrader valve cap on
the fire system distribution piping service port.
Check all cylinder gauges to confirm proper pressure is within the “green” range. If pressure is low, add nitro-
gen. Refer to “Adding Nitrogen to Tank(s)” on page 68.
Re-arm the control panel by placing the package in “Armed” mode.
