Undetected water damage, such as that caused by leaking pipes or corroded water heaters, cost homeowners tens of thousands of dollars each year.

Such repairs are time consuming and costly to correct. Applications could include computer room sub-floor areas, telephone equipment rooms, bathrooms, laundry rooms, any areas adjacent to a water storage tank or piping.

Also evaporative air conditioners, drip pans, overflows and/or drains. Using no mechanical parts, the GRI Water Sensors are triggered by a moisture bridge across the sensor contacts.
The GRI Water Sensors can be installed to detect a layer of water as minute as 1/16 of an inch in depth.

The 2600 Closed Loop Sensors use an external power source to energize a built-in relay contact so battery power is not recommended.

Used in a closed loop configuration, an alarm condition will occur when moisture is detected, or if power to the sensor is lost, and if the sensor should fail.

The relay output can be wired directly to any alarm panel or can be used to actuate an external device, i.e. transmitter, annunciator, etc.

The 2500 Open Loop Sensors use an external power source which will energize a built-in relay contact when water is detected.

With this configuration the sensors are not fail safe.

The relay output can be wired directly to any alarm panel or can be used to actuate an external device, i.e. transmitter, annunciator, etc.
