Installation Wiring Guidelines
All wiring must be installed in compliance with the
National Electrical Code and all applicable local codes and
any special requirements of the authority having jurisdic-
tion, using the proper wire size. 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.

devices should be color-coded to reduce the likelihood of

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 AWG 18. However, the screws and clamping plate can
accommodate wire sizes up to AWG 12. The use of twisted
pair wiring for the power (+ and –) loop is recommended
to minimize the effects of 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 control panel being used
before wiring the detector loops.

NOTE: Break the wire at each terminal to ensure that the
connections are supervised. Do NOT loop the wire

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

Tamper-resistant Feature
This detector includes a tamper-resistant feature that effec-
tively prevents removal of the detector without the use of
a tool. To make the detector tamper-resistant, break off
the smaller tab at the scribed line on the tamper resistant
tab, on the detector mounting bracket (see Figure 2), then
install the detector. To remove the detector from the bracket
once it has been made tamper resistant, use a small screw-
driver to depress the tamper-resistant tab located in the
slot on the mounting bracket and turn the detector coun-
terclockwise for removal.
