Before Installing
Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors, which pro-
vides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies of this
manual are available at no charge from System Sensor. (For
installation in Canada, refer to CAN/ULC-S524, Standard
for the Installation of Fire Alarm Systems and CEC Part 1,
Sec. 32.)
NOTICE: This manual should be left with the owner/user
of this equipment.

at least once a year.
General Description
The Model B112LP detector base is designed for use with
System Sensor model 2151 photoelectronic and 1151 ioniza-
tion detector heads. This four-wire base is equipped with
screw terminals for the connection of power, ground, and
an optional remote annunciator.
Mounting
The detector base mounts directly to 3-1/2 inch and 4-inch
octagon boxes and 4-inch square boxes, with or without
plaster rings. To mount the base, remove the decorative
ring by rotating it in either direction to unhook the snaps
before separating the ring from the base. Use the screws
supplied with the junction box to attach the base to the box
through the appropriate slots in the base (see Figure 1).
Position the decorative ring around the base and rotate it in
either direction until the ring snaps into place.
