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 for 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 condi-
tion, de-energizing the ORN conductor.
• 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.
HIGHLIGHT C
24-v power signal via ORN lead is removed at Smoke Detector in-
put on CTB (Control Terminal Board); all unit operations cease
immediately.
PREMIERLINK AND RTU OPEN CONTROLS
Unit operating functions (fan, cooling and heating) are terminated
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
GRA lead at Smoke Alarm input on CTB provides 24-v 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 24-v signal is conveyed to the 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. 46) for additional annunciation functions.
ADDITIONAL APPLICATION DATA
Refer to Factory-Installed Smoke Detectors for Small and Medi-
um Rooftop Units 2 to 25 Tons for discussions on additional con-
trol features of these smoke detectors including multiple unit coor-
dination. See Fig. 46.

Sensor and Controller Tests

SENSOR ALARM TEST
The sensor alarm test checks a sensor's ability to signal an alarm
state. This test requires the use of a field provided SD-MAG test
magnet.
NOTICE: OPERATIONAL TEST NOTICE
Failure to follow this NOTICE may result in an unnecessary
evacuation of the facility.
This test places the duct detector into the alarm state. Unless
part of the test, disconnect all auxiliary equipment from the con-
troller before performing the test. If the duct detector is connect-
ed to a fire alarm system, notify the proper authorities before
performing the test.
Sensor Alarm Test Procedure
1. Hold the test magnet where indicated on the side of the sensor
housing for seven seconds.
2. Verify that the sensor's Alarm LED turns on.
3. Reset the sensor by holding the test magnet against the sensor
housing for two seconds.
