1) Initial Detection
If your unit is equipped with Automatic Fire Suppression, the system is running, and the system is
functioning properly, the fire will be detected by the smoke sensor AND/OR primary heat detector. The
system will block the airflow, shut down the power to the motor controls, activate the strobe/horn, and
stop the valves from pulsing. If the primary heat detector has been activated, then the fire bottle will
discharge after 30 seconds. The activating device should be indicated on the panel display.
2) Secondary Detection
If the smoke sensor has tripped, but not a heat sensor, air flow should stop and heat should build up in
the filter compartment. This will cause the secondary heat sensors to trip.
Caution:
In the case of filter misalignment, the smoke sensor will trip, but the heat
sensor will not. This is due to smoke bypass.
3) Tube Heat Detection
If fire is present in the filter compartment, the temperature will rise and melts the tubing, This will
release the fire suppression agent.
4) Manual Detection
If the unit is still operating, immediately locate the manual fire suppression system Fire Pull. Operate
the switch by pulling the lever downward to engage the fire suppression system. The system will block
the airflow, shut down the power to the motor controls and turbo controller, and fill the filter
compartment with suppression agent after 20 seconds.
5) Alert
For safety, immediately follow your plant specified Fire Plan. The system is NOT tied into the plant fire
protection system by Clean Air Industries . Alert officials! 6) Extinguish
The suppression agent will contain and possibly extinguish a fire. However, due to the volatility of
materials trapped in the filters, they may reignite. It is recommended that Safety Personnel using
personal protective equipment immediately shut down main power to the unit and remove the filters
