Firestat, Smoke Detector, Water Detection Sensor

Component Operation and Maintenance

Firestat

The optional firestat is a bimetal operated sensing device with a normally closed switch. This device will shut down the entire unit when the inlet air temperature exceeds a preset point. It is connected between terminals 1 and 2 at plug P39.

Smoke Detector

The optional smoke detector power supply is located on the base of the upflow units, and at the top of downflow units. It is constantly sampling return air through a tube. No adjustments are required.

Water Detection Sensor

! CAUTION

Do not use near flammable liquids or for flammable liquid detection.

The optional water detection devices available are a point leak detection sensor and a zone leak detec- tion kit.

Liquitect Point Leak

Detection Sensor

The point leak detection sensor provides leak detection at a critical point. A simple two-wire connec- tion signals the alarms at a Liebert environmental unit or at a monitoring panel. Run wires to the Liebert unit and connect them to terminals 24 and 51, 55 or 56. Use NEC Class 2, 24V wiring. The sensor contains a solid state switch that closes when water is detected by the twin sensor probes. The sensor is hermetically sealed in all thread PVC nipple and is to be mounted where water problems may occur. The sensor should be located 6-8 feet (2-2.5m) from the environmental control unit in a wet trap or near a floor drain. It should not be mounted directly under the unit.
