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 annun-
ciator connections. The base also contains a resistor to
provide current limiting in the alarm state.

Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector base to be free from
defects in materials and workmanship under normal use and service for a
period of three years from date of manufacture. System Sensor makes no
other express warranty for this smoke detector base. No agent, represen-
tative, dealer, or employee of the Company has the authority to increase
or alter the obligations or limitations of this Warranty. The Company’s
obligation of this Warranty shall be limited to the repair or replacement
of any part of the smoke detector base which is found to be defective in
materials or workmanship under normal use and service during the three
year period commencing with the date of manufacture. After phoning
System Sensor’s toll free number 800-SENSOR2 (736-7672) for a Return
Authorization number, send defective units postage prepaid to: System
Sensor, Repair Department, RA #__________, 3825 Ohio Avenue, St.
Charles, IL 60174. Please include a note describing the malfunction and
suspected cause of failure. The Company shall not be obligated to repair
or replace units which are found to be defective because of damage,
unreasonable use, modifications, or alterations occurring after the date
of manufacture. In no case shall the Company be liable for any conse-
quential or incidental damages for breach of this or any other Warranty,
expressed or implied whatsoever, even if the loss or damage is caused by
the Company’s negligence or fault. Some states do not allow the exclu-
sion or limitation of incidental or consequential damages, so the above
limitation or exclusion may not apply to you. This Warranty gives you
specific legal rights, and you may also have other rights which vary from
state to state.

Mounting
This detector base mounts directly to 3-1/2- inch and
4-inch 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 detec-
tors), 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 sys-
tem 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.
CAUTION
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 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.
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 turned into
the base, completing the circuit.
Tamper-resistance Feature
NOTE: Do not use the tamper-resistance feature if the XR2
removal tool is to be used.
The tamper-resistant tab, in the detector mounting bracket,
can make the detector tamper-resistant by making it neces-
sary to use a small screwdriver or similar tool to detach the
detector from the bracket.

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 negative-in and negative-out
leads and permits the wiring of the loop to be checked for
continuity.
To make the detector tamper-resistant, use needle-nose
pliers to break the smaller tab at the scribed line on the
tamper- resistance tab. Figure 3A shows the location of this
tab on the detector mounting bracket.
To remove a detector from the bracket after it has been
made tamper resistant, use a small screwdriver or other
similar tool, to depress the tamper-resistance tab in the slot
on the mounting bracket, and rotate the detector counter-
clockwise (see Figure 3B).
NOTE: The decorative ring must be removed before the
smoke detector can be detached from the base
after the tamper-resistant capability is enabled.
