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.
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 allowable loop resistance. Consult the control panel manufacturer’s specifications for the total loop resistance allowed for the particular model control
panel being used before wiring the detector loops.
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 versatile 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 connections.

MOUNTING
The detector base mounts directly to 31/2- and 4-inch octagon boxes and
4-inch square boxes. 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 mounting slots in the base.

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 having jurisdiction, using the proper wire size. The conductors used to connect
smoke detectors to control panels and accessory devices should be colorcoded to reduce the likelihood of wiring errors. Improper connections can
prevent a system from responding properly in the event of a fire.
BOX
(NOT SUPPLIED)
For signal wiring (the wiring between interconnected detectors), it is recommended that the wire be no smaller than 16 gauge (1.5 square mm), and that

WIRING INSTRUCTIONS
NOTE: Refer to the manufacturer’s instructions for releasing device wiring.
To make the base tamper resistant, simply break off the tab on the base (see
Figure 4A), before installing the detector.
NOTE: To ensure that electrical connections are supervised, do NOT loop
wires under terminals 8, 9, 10, and 11. Cut the wire at each terminal.
To remove the detector from the base after it has been made tamper resistant,
insert a small screwdriver (see Figure 4B) into the small hole and press the
plastic lever away from the detector. Rotate the detector counterclockwise and
remove.
To make electrical connections, strip approximately 3/8 inch (1 cm) insulation
from the end of each wire, slide the bare wire end under the clamping plate,
and tighten the clamping plate screw. Use the strip gauges molded into the
inside and underside of the base for ease of wiring to terminals 1 and 4, and
to terminals 6 through 14, respectively.
NOTE: Head removal after activating the tamper-resistance feature first requires removal of the decorative ring.
The zone wiring of the detector base should be checked before installing the
smoke detector heads. The base contains a built-in shorting spring to make
this possible. After the detector base is wired and mounted to an electrical
box, position the shorting spring against terminal 3. This temporary connection energizes the supervisory relay and permits the wiring of the loop to be
checked for continuity.
