Water Leak Detector

Water splash on surface

Spot Detector for single-point water leak detection. These Spot Detectors are a cost-effective solution when you have an isolated area where a leak can occur. Spot Detectors work with detecting water leaks and other conductive fluid leaks.

These single-point leak sensors work great in drain pans, small mechanical rooms, floor drains, fire pump rooms, riser rooms, and other isolated areas where water will collect.

The RLE line of Spot detectors (SD) can send a leak signal back to a Zone Controller or Distance-Read style panel. Other SD sensors have a relay output and allow users to connect to their Building Monitoring System or other Monitoring platforms.

SD-R02

Spot Detector with Two Relay Outputs

SD-R02 Spot Detector

Water Leak Sensor With Two Relay Output

SD-R02 was is a Spot Detector with two relay outputs for detecting water leaks. Using a Double Pole Double Throw (DPDT) Form C relay output allows integration back to most alarm systems. The two relay outputs are isolated, so you can connect the Leak Sensor to two, independent systems. Both outputs have a Normally Open and Normally Closed contact for third-party system monitoring systems. From BAS, BMS, Remote Annunciator Panels, Security Panels, and other Alarm systems, this water leak sensor has you covered. If you have needs to connect to two different monitoring systems, save money with one leak sensor that does both.
