Model GPL+GLU limited service fire pump controllers are designed to start an electric motor driven fire pump. It can
either start the fire pump manually through the local start pushbutton or automatically through the sensing of a
pressure drop in the sprinkler system. The fire pump controller is supplied with a pressure transducer. The fire
pump can be stopped manually with the local stop pushbutton or automatically after the expiration of a field
programmable timer. In both cases, stopping is only allowed if all starting causes have disappeared.
