How the WHDR™ Kitchen Fire Suppression System Works
Fire is detected by mechanical links, thermo-bulb detectors, or electric DETECT-A-FIRE® (DAF) heat detectors. The system may also be manually activated via a remote pull station.
The XV™ Control System simultaneously actuates the pressurized agent storage containers, shuts down fuel and electrical power sources, and activates the building fire alarm.
The APC wet chemical agent is discharged through a fixed piping network and strategically positioned nozzles.
The agent suppresses flames and creates a foam blanket over grease surfaces, preventing reflash until the hazard cools.
