Test Procedure - CaptiveAire EWC Installation, Operation And Maintenance Manual

Test Procedure

1. Remove threaded nozzle caps.
2. Remove hood filters. This will expose the Firestat(s) and the duct and plenum drops.
3. Place testing balloons over all nozzles (appliance, duct, and plenum).
4. Turn the Nitrogen Service Cylinder on to pressurize the system.
CAUTION!: Supplied Nitrogen Pressure Must be 25 psig Minimum to 200 psig Maximum.
5. Activation of the fire system may be initiated by two methods.
• Method 1- Use a portable heat source to apply heat to the duct Firestat in accordance with the
manufacturer's instructions. Please refer to applicable detector manufacturer's manual. Heat should
activate the fire system, and nitrogen from the test cylinder should activate all fire system actuators
and begin to fill the service balloons. The use of a torch or flame is strictly prohibited.
• Method 2 - Lift the cover to the manual release station and "push" the manual release station button
to activate the fire system. The manual release station can be re-set by twisting the push button in a
clockwise motion.
6. Verify that the control panel has activated and that the audible alarm is sounding.
7. Ensure the PAK and all SVAs have actuated, with the piston in the fully extended and locked position.
8. Verify that there are no leaks in the actuation line.
9. Verify that the solenoid is in the energized state.
10. Verify that all balloons are filled.
11. Verify fuel to all appliances under the protected hood has shut off.
12. Verify the makeup air supplied internally to the hood has shut off.
13. Verify electric power shutdown.
14. If all of the above is confirmed, reset the control panel per "Reset Overview" on page 53.
15. Turn the Nitrogen Service Cylinder off.
16. Re-install all nozzle seals and caps. Refer to "Nozzles" on page 39.
