Fig. 23 --Typical SmokeDetector System Wiring
Highlight C: 24--vpower signal via ORN lead is removed
at Smoke Detector input on LCTB; all unit operations
cease immediately.
PremierLink and RTU--MP Controls: 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 24--v
power to GRA conductor.
Highlight E: GRA lead at Smoke Alarm input on LCTB
provides 24--vsignal to FIOP DDC control.
Premier--Link: 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--MP: The 24--v signal is conveyed to RTU--MP’s
J1--10 input terminal. This signal initiates the FSD
sequence by the RTU--MPcontrol. FSD status is reported
to connected BASnetwork.
Using Remote Logic: Five conductors are provided for
field use (see Highlight F) for additional annunciation
functions.
Additional Application Data — Refer to Catalog No.

features of these smoke detectors including multipleunit
coordination. See Fig. 23.

Sensor and Controller Tests

Sensor Alarm Test
The sensoralarm test checks a sensor’s ability to signal an
alarm state. This test requires that you use a field provided
SD--MAG test magnet.
OPERATIONAL TEST HAZARD
Failure to follow this caution may result in personnel
and authority concern.
This test places the duct detector into the alarm state.
Unless part of the test, disconnect all auxiliary
equipment from the controller before performing the
test. If the duct detector is connected to a fire alarm
system, notify the proper authorities before
performingthe test.
CAUTION
!
Sensor Alarm Test Procedure
1. Hold the test magnet where indicated on the side of
the sensor housing for seven seconds.
2. Verifythat the sensor’s Alarm LED turns on.
3. Reset the sensor by holding the test magnet against
the sensor housing for two seconds.
4. Verifythat the sensor’s Alarm LED turns off.
ControllerAlarm Test
The controller alarm test checks thecontroller ’sability to
initiate and indicate an alarm state.
