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, please refer to CAN4-S524, Standard

for the Installation of Fire Alarm Systems and CEC Part 1,

General Description

The model B116LP plug-in detector base is used with

System Sensor model 1151, 1151A, and 1151E ionization

detector heads and model 2151, 2151A, and 2151E photo-

electronic 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.

D150-01-00 2 I56-599-03R

The B116LP base is intended for use in 2-wire systems,

with screw terminals provided for power and relay contact

connections. These bases MUST be current limited by the

system control panel in the alarm state.

Mounting

This detector base mounts directly to 3-1/2-inch and 4-

inch octagon boxes, and 4-inch square boxes (with or with-

out plaster rings). To mount, remove decorative ring by

turning it in either direction to unhook the snaps, then sep-

arate 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 con-

ductors used to connect smoke detectors to control panels

and accessory devices should be color-coded to prevent

wiring mistakes. Improper connections can prevent a sys-

tem from responding properly in the event of a fire.

For signal wiring (the wiring between inter-connected

detectors), it is recommended that the wire be no smaller

than 18 gauge. Wire sizes up to 12 gauge may be used with

the base. For best system performance, the power (+) and

(–) loop wires should be twisted pair and installed in sep-

arate 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.

Locate installations where normal ambient temperatures do

not exceed 100°F.

Wiring Instructions

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 gauges molded into the inside

CAUTION

and underside of the base for ease of wiring to terminals 1

through 5, and to terminals 12 through 14, respectively.

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 prod-

uct. 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.

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 short-

ing 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 tem-

porary connection shorts the positive-in and positive-out

leads and permits the wiring of the loop to be checked for

continuity.

CAUTION

Once all the detector bases have been wired and mounted,

and the loop wiring has been checked, the detector heads

may be installed in the bases. The shorting spring in the

base will disengage automatically when the detector head

is removed from the base. DO NOT remove the shorting

spring since it reengages as the detector head is fully

turned into the base, completing the circuit.

Tamper-resistance Feature

Do NOT use the tamper-resistance feature if the XR2

Removal Tool will be used.

This detector base includes a tamper-resistance feature that

prevents removal of the detector without the use of a tool.

To activate this feature, break off the tab on the detector

base shown in Figure 3A, then install the detector. To

remove the detector from the base once the tamper-resist-

ance feature has been activated, place a small-bladed

screwdriver into the small hole on the side of the base and

push plastic lever away from the detector head (see Figure

3B). This will allow the detector to be rotated counter-

clockwise for removal.

NOTE: Head removal after the tamper-resistance feature

has been activated requires removal of the decora-

tive ring.

The tamper-resistance feature can be defeated by breaking

and removing the plastic lever from the base, however this

prevents using the feature again.
