George Risk Industries' GRI 2650 - Fluid Sensor 24VAC Circuit are triggered by a moisture bridge across the sensor contacts. The GRI 2650 Sensor can be installed to detect a layer of liquid as minute as 1/16 of an inch in depth. These sensors use an eXternal power source to energize a built-in relay contact (battery power is not recommended.) Used in an active SPDT configuration, an alarm condition will occur when moisture is detected, power to the sensor is lost or if the sensor should fail. The relay output can be wired directly to a control panel or can be used to actuate an eXternal device, i.e. transmitter, annunciator, etc., and can be used to monitor evaporative air conditioners, drip pans, overflows and/or drains.
Note:Using no mechanical parts

INSTALLATION INSTRUCTIONS:
GRI 2650 - is used to detect the presence of fluid and to provide a relay output for signal or control of an external device. The switch operates on 24 Volts AC and functions as a Normally Open or Normally Closed Sensor. The red and black wires power the switch while the brown, white and green wires are the relay output wires. After installation these units should be tested with a damp sponge or paper towel and inspected annually. If there is any corrosion or damage the sensors should be replaced.
