Before Installing
Please thoroughly read the system wiring and installation
manuals, and manual I56-407,
Guide for Proper Use of
System Smoke Detectors,
which provides detailed informa-
tion on detector spacing, placement, zoning, and special
applications. Copies of these manuals are available at no
charge from System Sensor.
NOTICE:
This manual should be left with the owner/user
of this equipment.
IMPORTANT:
The detector used with these bases must
be tested and maintained regularly following NFPA 72
requirements. The detectors should be cleaned at least
once a year.
Mounting
The detector base mounts directly to 3
1⁄2
- and 4-inch octa-
gon and 4-inch square boxes, with or without a plaster
ring.
To mount, remove the decorative ring by rotating it in either
direction to unhook the snaps. Then, separate the ring from
the base. Install the base on the box, using the screws sup-
plied with the junction box and the appropriate slots in the
base. Replace the decorative ring on the base and rotate it in
either direction until the ring snaps in place (see Figure 1).

Installation Guidelines
All wiring must be installed in compliance with all appli-
cable local codes and any special requirements of the local
authority having jurisdiction, using the proper wire sizes.
The conductors used to connect smoke detectors to control
panels and accessory devices should be color-coded to
reduce the likelihood of wiring errors. Improper connec-
tions can prevent a system from responding properly in the
event of a fire.
For signal wiring (the wiring between interconnected detec-
tors), it is recommended that the wire be no smaller than
18 gauge (1.0 square mm). However, wire sizes up to 12
gauge (3.3 square mm) can be used with the base. The
use of twisted pair wiring or shielded cable for the power
(+ and –) loop is recommended to minimize the effects of
electrical interference.
If shielded cable is used, the shield connection to and from
the detector must be continuous by using wire nuts, crimp-
ing, or soldering, as appropriate, for a reliable connection.
Alarm system control panels have specifications for allow-
able loop resistance. Consult the control panel specifica-
tions for the total loop resistance allowed before wiring
the detector loops.
