Method and System for Liquid Cleaning of Smoke Sensor Heads
A system and method for cleaning the fire detection sensor of a fire detection device, such as a smoke detector, includes flowing halocarbon liquid over the fire detection sensor. A pump continuously recirculates the halocarbon liquid between a sensor holder and a reservoir, while a cleaning action is applied by an agitator to the fire detection sensor while it is under a stream of the liquid or in a bath of the liquid. The halocarbon liquid is typically an industrial electronics cleaner such as Novec™, which removes dirt, dust, grease and oil from the fire detection sensor without harming electronic components.
