How the system works:

1. Fire Detectors sense fire heat in work area, plenum or duct... A signal is sent to the Control Panel
    

2. Control Panel electrically activates Cylinder Control Head, which open cylinder valve.
    

3. Dry Chemical is propelled by stored pressure through Discharge Pipes and Nozzles into the protected area.
    

4. Fire is suppressed as Control Panel sounds alarm, notifies fire authorities and shuts down airflow in hazard area.

How the system works:

1. 
   A SPILL FIRE BEGINS - Spill fires can be caused by careless handling of the hose and nozzle, combined with mechanical or electric sparks, smoking or any open flame. Even driving away from the pumps with nozzle still in the tank can cause a spill and provide the spark for the ignition.
    

2. FIRE DETECTORS SENSE THE FIRE - Strategically placed heat sensors pick up the heat of the spill fire and promptly send a signal to the fire system for immediate actuation.
    

3. THE SYSTEM ACTUATES - Dry Chemical fire suppression agent is stored in steel containers connected by pipe to nozzles aimed at the hazard area. Immediately upon actuation, the chemical envelops the area of the spill fire, allowing vehicle occupants TIME to exit their vehicles and leave the vicinity of the fire.
    

4. MANUAL BACKUP - As a backup of the automatic detection, manual actuation stations are located where station attendants can actuate the system at the first sign of the spill fire
