HVAC/Air Conditioner Condensate Pan Overflow Detection Alarm

Model RS-097

FloodMaster Air Conditioner Condensate Overflow Detection & Alarm Systems are designed to sound an audible alarm when the sensor puck comes in contact with conductive liquid (such as water). Specifically designed for air conditioning, HVAC, HVACR and water chiller condensate pans, these units feature an elevated (1/2″) sensor puck which will allow for a normal amount of water in the pan, but will activate in a near-overflow situation.

The RS-097 is especially suited for the following applications:

Fan coil heating/cooling units, HVAC units with overflow pans, equipment protection for healthcare and dental facilities, any area requiring leak detection and communication via a building management system
