1.Unscrew the two screws holding the Return Air Sensor detector plate. (See Fig. 23.) Save the screws.

2.Remove the Return Air Sensor and its detector plate.

3.Rotate the detector plate so the sensor is facing out- wards and the sampling tube connection is on the bot- tom. (See Fig. 24.)

4.Screw the sensor and detector plate into its operating position using screws from Step 1. Make sure the sampling tube connection is on the bottom and the ex- haust tube is on the top. (See Fig. 23.)

5.Connect the flexible tube on the sampling inlet to the sampling tube on the basepan.

6.For units with an economizer, the sampling tube is in- tegrated into the economizer housing but the connec- tion of the flexible tubing to the sampling tube is the same.

FIOP Smoke Detector Wiring and Response

All units: FIOP smoke detector is configured to automatically shut down all unit operations when smoke condition is detected. See Fig. 25, Smoke Detector Wiring.

Highlight A: JMP 3 is factory-cut, transferring unit control to smoke detector.

Highlight B: Smoke detector NC contact set will open on smoke alarm condition, de-energizing the ORN conductor.
