D100-55-00 3 I56-733-10
Volt D.C. power supply to a 4" square junction box 2-1/8" deep only.
(If necessary, add an extension ring if the selected box does not have
adequate volume.) The power supply may be mounted remotely from
the detector.
• All wiring must be performed by a licensed electrician and installed in
compliance with the National Electrical Code, applicable local codes,
and any special requirements of the local authority having jurisdiction.
• Use only the specified wire gauge. Maximum interconnect bus length
is 5,000 feet, #18 AWG or larger two-conductor stranded cable.
• The detector includes a tamper-resist feature that, when activated, re-
quires a tool for detector removal. The following detector installation
instructions include how to activate this feature.
Installation Instructions
1. Turn off power at main service panel.
2. Using wire connectors, attach either black wire from power supply to
black AC power wire. Attach other black wire from power supply to
white AC neutral wire.
3. Using wire connectors, connect red and gray power supply output
wires to the bus line wires supplying power to the remote detectors.
(See Figure 7.) Use color-coded bus wires.
4. Mount power supply to junction box and cover junction box with a 4"
square box cover, using box mounting screws.
5. Install a junction box where you plan to install the detector. (See type
and size for junction box above.)
6. Install bus line wires from power supply output to junction box. Use
#14-18 AWG wire only. See Figure 7 to determine maximum power bus
length for wire size and number of interconnected detectors.
7. Connect color-coded DC power bus wires to power input screw termi-
nals, located on detector back. If detectors will be interconnected or the
relay used, see following sections for specific installation instructions.
8. Remove detector from mounting bracket by turning the detector
counter-clockwise and pulling the detector away from the bracket.
9. Remove small tab on mounting bracket to activate tamper-resist fea-
ture, if desired. (To release a detector with this feature, push up on
locking tab with screwdriver while turning detector counterclockwise.)
10. Install mounting bracket to junction box.
11. Connect power wires to detector(s) as shown in Figure 8. Be sure to
tighten each terminal screw to secure wire in place. Tug wire to be sure
it is connected properly.
12. Attach smoke detector to mounting bracket by aligning arrows on side
of mounting bracket 1-inch to the right of the nib on the detector. Ro-
tate until the arrow and nib line up. (See Figure 8).
13. After installing all detectors, turn on power at the main service panel.
14. Check for the green LED to flash about once every 30 to 40 seconds.
This means the detector is receiving power. Check all detectors.
Note: If the LED does not flash, power is not getting to the smoke detec-
tor. Check wiring. If LED still does not flash, return the smoke de-
tector to the manufacturer for repair.
15.Test each detector in the system. (See “Testing” below for more de-
tailed instructions.)
