This is an air distribution system that will alarm when the supplied air falls below a preset air pressure setting. When the inlet air pressure falls below the preset level specified in the model number, a pressure switch connects the internal 9 volt transistor battery to the alarm (rated 119dB(A). The alarm will continue to operate until the pressure in the system exceeds the preset level.
