Before Installing

Please thoroughly read the System Sensor manual I56-407,
Guide for Proper Use of System Smoke Detectors, which pro­vides detailed information on detector spacing, placement,
zoning, wiring, and special applications. Copies of this
manual are available at no charge from System Sensor. (For
installations in Canada, please refer to CAN4-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.

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 B110RLP plug-in detector base is used with System
Sensor model 1151 and 1151A ionization detector heads and
model 2151 and 2151A photoelectronic 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 detector bases.

This base is intended for use in 2-wire systems, with screw
terminals provided for power, ground, and remote annun­ciator connections. The base also contains a resistor to pro­vide current limiting in the alarm state.

Mounting

This detector base mounts directly to 3-1/2- inch and 4­inch octagon boxes, and 4-inch square boxes (with or with­out plaster rings). To mount, remove decorative ring by
turning it in either direction to unhook the snaps, then sep­arate the ring from the base. Install the base to the box
using the screws supplied with the junction box and the
appropriate mounting slots in the base. Place decorative
ring onto base, then turn in either direction until the ring
snaps in place (see Figure 1).

Installation Guidelines

All wiring must be installed in compliance with the
National Electrical Code and the local codes having juris­diction. Proper wire gauges should be used. 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 recommended that the wire be no smaller
than 18 gauge (1.0 square mm). Wire sizes up to 12 gauge
wire (2.5 square mm) may be used with the base. For best
system performance, the power (+) and (–) loop wires
should be twisted pair and installed in separate grounded
conduit to protect the loop from extraneous electrical inter­ference.

Smoke detectors and alarm system 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.

For system supervision — For terminals 2, 3, and 5 do not
use looped wire under terminals. Break wire run to provide
system supervision of connections.

Wire connections are made by simply stripping insulation
from the end of the wire, sliding the bare end of the wire
under the clamping plate, and tightening the clamping
plate screw. Use the strip gauge molded into the base for
ease of wiring to terminals 1 through 5.

System Sensor smoke detectors and mounting bases are
marked with a compatibility identifier located as the last
digit of a five digit code stamped on the back of the prod­uct. Connect detectors/mounting bases only to compatible
control units as indicated in System Sensor’s compatibility
chart which contains a current list of UL listed control units
and detector head/base combinations. A copy of this list is
available from System Sensor upon request.

CAUTION

A78-1175-01

The zone wiring of the detector base should be checked
before the detector heads are installed in them. To make
this possible, this base contains a special spring-type short­ing jumper. After a detector base is properly wired and
mounted on an electrical box, make sure that the jumper
spring is in contact with the base of Terminal 3. This tem­porary connection shorts the negative-in and negative-out
leads and permits the wiring of the loop to be checked for
continuity.
