The Extinguishing Assembly RS-EXT02 is designed to work in conjunction with the RS-PCUSP1L control unit and RS-SD02 Spark Detectors. When the control module gets a signal that a hazard has been detected, the extinguishing assembly is activated. A water spray is initiated inside the piping system to extinguish sparks or glowing embers that could cause fire or explosion. The Extinguishing Assembly RS-EXT02 is FM Approved and ATEX Certified.
