Completing Installation of Return Air Smoke
Sensor
1. Unscrew the two screws holding the Return Air Sensor
detector plate. See Fig. 28. Save the screws.
2. Remove the Return Air Sensor and its detector plate.
3. Rotate the detector plate so the sensor is facing outwards
and the sampling tube connection is on the bottom. See
Fig. 29.
4. Screw the sensor and detector plate into its operating posi-
tion using screws from Step 1. Make sure the sampling
tube connection is on the bottom and the exhaust tube is
on the top. See Fig. 29.
5. Connect the flexible tube on the sampling inlet to the sam-
pling tube on the basepan.
6. For units with an economizer, the sampling tube is inte-
grated into the economizer housing but the connection 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. 30, 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 con-
dition, de-energizing the ORN conductor.
HIGHLIGHT C
24-v power signal via ORN lead is removed at Smoke Detector
input on CTB; all unit operations cease immediately.
PREMIERLINK CONTROL
Unit operating functions (fan, cooling and heating) are termi-
nated as described above.
HIGHLIGHT D
On smoke alarm condition, the smoke detector “NO Alarm”
contact will close, supplying 24-v power to GRA conductor.
HIGHLIGHT E
WHT lead at Smoke Alarm input on CTB provides 24-v signal
to FIOP DDC control.
PREMIER-LINK
This signal is conveyed to PremierLink FIOP’s TB1 at terminal
TB1-6 (BLU lead). This signal initiates the FSD sequence by
the PremierLink control. FSD status is reported to connected
CCN network.
RTU-OPEN
The 24-v signal is conveyed to RTU-Open’s J1-10 input termi-
nal. This signal initiates the FSD sequence by the RTU-Open
control. FSD status is reported to connected BAS network.
USING REMOTE LOGIC
Six conductors are provided for field use (see Highlight F in
Fig. 30) for additional annunciation functions.
