BEFORE INSTALLING
Please read thoroughly System Sensor’s
Applications Guide for System Smoke
Detectors
(SPAG91), which provides detailed information on detector spacing,
placement, zoning, wiring, and special applications. This is available online
from System Sensor’s web site: www.systemsensor.com.
NOTICE:
This manual should be left with the owner/user of this equipment.
IMPORTANT:
The detector used with this base must be tested and maintained
regularly following NFPA 72 requirements. The detector used with this base
should be cleaned at least once a year.
GENERAL DESCRIPTION
The B114LPBT detector base is designed for use with System Sensor model
2151 photoelectronic and 1151 ionization detector heads. The capability of
plugging these detectors into a variety of special bases makes them more ver-
satile than equivalent direct-wired models. Refer to the System Sensor catalog
for other available plug-in bases. The B114LPBT base is intended for use in
4-wire systems with terminals provided for remote annunciator and relay con-
nections.
MOUNTING
The detector base mounts directly to 3

- and 4-inch octagon boxes and
4-inch square boxes. To mount the base, remove the decorative ring by rotat-
ing 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 mounting slots in the base.
Position the decorative ring around the base and rotate it in either direction
until the ring snaps into place (see Figure 2).

INSTALLATION GUIDELINES
All wiring must be installed in compliance with the National Electrical Code,
all applicable local codes, and any special requirements of the authority hav-
ing jurisdiction, using the proper wire size. 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 connections can
prevent a system from responding properly in the event of a fire.
For signal wiring (the wiring between interconnected detectors), it is recom-
mended that the wire be no smaller than 16 gauge (1.5 square mm), and that
two- or three-conductor wire be no smaller than 18 gauge (1.0 square mm).
For best performance, alarm loop conductors should be installed in separate
grounded conduit or shielded cable to protect the alarm loop from extraneous
electrical interference.
Smoke detectors and alarm systems control panels have specifications for al-
lowable loop resistance. Consult the control panel manufacturer’s specifica-
tions for the total loop resistance allowed for the particular model control
panel being used before wiring the detector loops.
