Completing Installation of Return Air Smoke
Detector
Use the following steps to complete the installation of the re-
turn air smoke detector.
1. Unscrew the two screws holding the return air sensor
detector plate (see Fig. 40). Save the screws.
2. Remove the return air smoke sensor module and its detec-
tor plate.
3. Rotate the detector plate so the sensor is facing outwards
and the sampling tube connection is on the bottom (see
Fig. 41).
4. Screw the sensor and detector plate into its operating posi-
tion using screws from Step 1. Ensure the sampling tube
connection is on the bottom and the exhaust tube is on the
top.
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 connecting 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 a smoke condition is detected. See
Fig. 42 for 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 using the ORN lead is removed at the Smoke
Detector input on CTB; all unit operations cease immediately.
RTU-OPEN CONTROLS
Unit operating functions (fan, cooling and heating) are termi-
nated as described in this section.
HIGHLIGHT D
On smoke alarm condition, the smoke detector NO Alarm con-
tact will close, supplying 24-v power to GRA conductor.
HIGHLIGHT E
GRA lead at Smoke Alarm input on CTB provides 24-v signal
to FIOP DDC control.
RTU-OPEN
The 24-v signal is conveyed to RTU-OPEN-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
Five conductors are provided for field use (see Highlight F in
Fig. 42) for additional annunciation functions.
