System Sensor sprinkler monitoring devices provide the peace of mind property owners need. Our products can expertly monitor fire sprinkler systems and control valves to enable personnel to respond quickly to changes in fire sprinkler system status. Waterflow detectors monitor the flow of water to sprinkler heads. Supervisory switches help prevent tampering or incorrect setting of valve controls. Pressure switches indicate a discharge from a sprinkler. All three also come in explosion-proof versions for hazardous environments.
