FIOP Smoke Detector Wiring and Response
All units: The FIOP smoke detector is configured to automati-
cally shut down all unit operations when a smoke condition is
detected. See Fig. 35 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 Smoke
Detector input on Central Terminal board (CTB); all unit oper-
ations cease immediately.
PREMIERLINK™ AND RTU-OPEN CONTROLS
Unit operating functions (fan, cooling and heating) are termi-
nated as described above.
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 LCTB provides 24-v sig-
nal to FIOP DDC control.
PREMIERLINK
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 the RTU-OPEN J1-10 input ter-
minal. This signal initiates the FSD sequence by the RTU-OPEN
control. FSD status is reported to connected BAS network.
USING REMOTE LOGIC
Five field use conductors are provided for additional annuncia-
tion functions.
