[7] FIELD WIRING; INSTALLATION GUIDELINES

All wiring must be installed in compliance with the National Electrical Code
and the local codes having jurisdiction. Proper wire gauges should be used.
The conductors used to connect smoke detectors to control panels and acces-
sory devices should be color-coded to prevent wiring mistakes. Improper con-
nections can prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between detectors or from detector to auxiliary
devices), it is usually recommended that single conductor wire be no smaller
than 18 gauge. The duct smoke detector terminals accommodate wire sizes up
to 12 gauge. Flexible conduit is recommended for the last foot of conduit; solid
conduit connections may be used if desired.
Duct smoke detectors and alarm system control panels have specifications for
Signaling Line Circuit (SLC) wiring. Consult the control panel manufacturer's
specifications for wiring requirements before wiring the detector loop.
[7.1] WIRING INSTRUCTIONS
Disconnect power from the communication line before installing the D365PL
duct smoke detector.
The D365PL detectors are designed for easy wiring. The housing provides a
terminal strip with clamping plates. Wiring connections are made by sliding
the bare end under the plate, and tightening the clamping plate screw. See
Figure 6 below for system wiring.

[8] VERIFICATION OF OPERATION

[8.1] INSTALL THE COVER
Install the covers making sure that the cover fits into the base groove. Tighten
the seven screws that are captured in the covers. Note that the cover must be
properly installed for proper operation of the sensor.
[8.2] POWER THE UNIT
Activate the communication line on terminals COM + and COM –.
[8.3] DETECTOR CHECK
Standby – If programmed by the system control panel, look for the presence of
the flashing LEDs through the transparent housing cover. The LED will flash
with each communication.
Trouble – If programmed by the system control panel and the detector LEDs
do not flash, then the detector lacks power (check wiring, missing or improp-
erly placed cover, panel programming, or power supply), the sensor head is
missing (replace), or the unit is defective (return for repair).
[8.4] DUCT SMOKE DETECTOR TEST & MAINTENANCE PROCEDURES
Test and maintain duct smoke detectors as recommended in NFPA 72. The
tests contained in this manual were devised to assist maintenance personnel
in verification of proper detector operation.

Before conducting these tests, notify the proper authorities that the smoke
detection system will be temporarily out of service. Disable the zone or system
under test to prevent unwanted alarms.
[8.4.1] TEST THE UNIT
1. M02-04-00 Magnet Test (not included) – This sensor can be function-
ally tested with a test magnet. The test magnet electronically simulates
smoke in the sensing chamber, testing the sensor electronics and connec-
tions to the control panel.
2. Remote Test Accessory – The use of a remote accessory for visible indica-
tion of power and alarm is recommended.
Verify system control panel alarm status and control panel execution of
all intended auxiliary functions (i.e. fan shutdown, damper control, etc.).
Two LEDs on the sensor are controlled by the panel to indicate sensor
status. Coded signals, transmitted from the panel, can cause the LEDs
to blink, latch on, or latch off. Refer to the control panel technical docu-
mentation for sensor LED operation and expected delay to alarm.
[8.4.2] THE DETECTOR MUST BE RESET BY THE SYSTEM CONTROL
PANEL
[8.4.3] SMOKE ENTRY TEST USING AEROSOL SMOKE
This test is intended for low-flow systems (100-500 FPM). If the air speed is
greater than 500 FPM, use a conventional manometer to measure differential
pressure between the sampling tubes, as described in Section 6 Measurement
Tests.
Drill a ¼-inch hole 3 feet upstream from the duct smoke detector. With the air
handler on, measure the air velocity with an anemometer. Air speed must be
at least 100 FPM. Spray aerosol smoke* into the duct through the ¼-inch hole
for five seconds. Wait two minutes for the duct smoke detector to alarm. If the
duct smoke detector alarms, air is flowing through the detector. Remove the
duct smoke detector cover and blow out the residual aerosol smoke from the
chamber and reset the duct smoke detector at the panel. Use duct tape to seal
the aerosol smoke entry hole. Remember to replace the cover after the test or
the detector will not function properly.
Additionally, canned aerosol simulated smoke (canned smoke agent) may be
used for smoke entry testing of the smoke detector. Tested and ap proved aero-
sol smoke products are:

Canned aerosol simulated smoke (canned smoke agent) formulas will vary
by manufacturer. Misuse or overuse to these products may have long term
adverse effects on the smoke detector. Consult the canned smoke agent manu-
facturer's published instructions for any further warnings or caution state-
