Fire Protection Equipment

The Raptor Spark® Detection and Extinguishing System is an FM Approved safety device that is designed to detect and extinguish sparks and glowing embers that are traveling through a duct system. The hazard is detected by infrared sensors and extinguished with water spray nozzles within milliseconds of detection. The Raptor Spark® detection unit module has the capacity to receive hazard alert signals from multiple components (Dust Probes & Thermal Probes) and monitor multiple duct-zones and vessels. The Raptor Spark® Detection and Extinguishing System is an essential Fire Protection, Fire Isolation and Diversion device that is commonly installed with Raptor Gate™ High Speed Abort Gates, FireBreak Shutters, VIGILEX Explosion Vents and explosion certified VDL Rotary Valves. Typical automatic functions include hazard detection, system shut-down, isolation/abort, and extinguish and/or suppression.
