1. Unscrew the two screws holding the Return Air
Sensor detector plate. See Fig. 49. 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. 50.

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. 50.
5. Connect the flexible tube on the sampling inlet to the
sampling tube on the base pan.
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. 51, Typical Smoke
Detector System 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.
Highlight C:
24V power signal via ORN lead is removed
at Smoke Detector input on CTB (Control Terminal
Board); all unit operations cease immediately.
PremierLink Control:
Unit operating functions (fan,
cooling and heating) are terminated as described above. In
addition:
Highlight D:
On smoke alarm condition, the smoke
detector NO Alarm contact will close, supplying 24V
power to GRA conductor.
Highlight E:
GRA lead at Smoke Alarm input on CTB
provides 24V signal to FIOP DDC control.
PremierLink:
This signal is conveyed to PremierLink
FIOPs 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
24V
signal is
conveyed to
RTU--OPEN’s J1--10 input terminal. 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. 51) for additional
annunciation functions.
Additional Application Data —
Refer to Catalog No.
HKRNKA--1XA for discussions on additional control
features of these smoke detectors including multiple unit
coordination. See Fig. 51.
