Completing Installation of Return Air Smoke
Sensor
SAMPLE TUBE
C09686
Fig. 44 -- Return Air Detector Shipping Position
1. Remove blower access panel.
2. Locate bracket and secure and secure to fan deck. Se-
cure with #10 screws provided.
3. Remove plastic cover from sensor. See Fig. 44.
4. Mount the sensor to the bracket as shown using two
#8 screws. See Fig. .
5. Install plastic adapter to the smoke sensor.
6. Locate short pick--up tube and EMT to seal--tight as-
sembly. Secure adapter to pick--up tube.
7. Locate seal--tight assembly and secure it to the ad-
apter, Snap seal--tight into the smoke sensor.
8. Remove
⅞
” knockout plug in blower side plate. Refer
to Fig. For location depending on the configuration
of the unit.
9. Snap seal--tight assembly into knockout hole.
10. Route seal--tight assembly to connector and complete
connection. See Fig. . Ensure seal--tight assembly
does not interfere with blower operation. Cut away
any excess seal--tight material.
11. Route 10 ft. (3.05m) cable through opening on lower
right of control box. Route with indoor fan wires se-
curing cable to wires with wire ties provided.
12. Route into sensor through knockout hole and plug end
into theRJ45 connector. Ensure knockout hole is
sealed with grommet mounted to cable.
13. Reinstall plastic cover.
14. Installation is now complete. Refer to Sensor and
Controller section for operation.
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. 46, 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.
S
For units with an economizer, the sampling tube is
integrated into the economizer housing but the
connection of the flexible tubing to the sampling tube is
the same.
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 the
RTU--OPEN 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. 46) 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. 46.
