For signal wiring (the wiring between interconnected detectors), it is recom-
mended 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 extra-
neous electrical interference.
Smoke detectors and alarm system control panels have specifications for al-
lowable loop resistance. Consult the control panel manufacturer’s specifica-
tions 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 com-
patibility 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 con-
tains a current list of UL listed control units and detector head/base combina-
tions. 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 spe-
cial 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.
Once all the detector bases have been wired and mounted, and the loop wir-
ing 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 de-
tector tamper-resistant by making it necessary to use a small screwdriver or
similar tool to detach the detector from the bracket.
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 counterclock-
wise (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.

THREE-YEAR LIMITED WARRANTY
System Sensor warrants its enclosed smoke detector base to be free from defects in ma-
terials 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, representative, dealer, or employee of the Company has the au-
thority 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: Honeywell,
12220 Rojas Drive, Suite 700, El Paso TX 79936, USA. 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 consequential 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 exclusion 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.
