All units: FIOP smoke detector is configured to
automatically shut down all unit operations when smoke
condition is detected. See Fig. 26, 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 condition,
conductor.
Highlight C: 24- - v power signal via ORN lead is removed
at Smoke Detector input on CTB; all unit operations cease
immediately.
RTU Open 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: WHT lead at Smoke Alarm input on CTB
provides 24- - v signal to FIOP DDC control.
RTU Open: The 24- - v 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) for additional annunciation
functions.

features of these smoke detectors including multiple unit
coordination. See Fig. 26.
Sensor and Controller Tests
Sensor Alarm Test
The sensor alarm test checks a sensor's ability to signal an
alarm state. This test requires that you use a field provided
SD- - MAG test magnet.
CAUTION
!
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
performing the test.
