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
installation in Canada, please refer to CAN4-S524, Standard
for the Installation of Fire Alarm Systems and CEC Part 1,
Sec. 32.)

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 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.
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 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 prevent
wiring mistakes. Improper connections can prevent a system 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 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.
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 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.
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 positive-in and positive-out
leads and permits the wiring of the loop to be checked for
continuity.
