Description
GRI 2500 Water Sensor with Relay Contact, Open Loop 12V DC, Gray
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.
