All wiring must be installed in compliance with applicable
codes and the authority 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 intercomected de-
tectors), 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
+IN/OUT ,-IN and -OUT 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 control panel being used
before wiring the detector loops.
CAUTION:Do not loop wire under terminals. Break wire
run to ensure supervision of connections.
Wire connections are made by stripping about 3/8" of
insulation from the end of the wire (use strip gauge
molded in base), sliding the bare end of the wire under the
clamping plate, and tightening the clamping plate screw.
Two-wire initiating devices receive their power from the
initiating circuit of a control panel. Electrical specifica-
tions of the control panel and the detector-base combina-
tion must be compatible for the system to function
properly.
The zone wiring of the detector bases should be checked
before the detector heads are installed.
Tamp®rLres[stanl: F®atur®
This -detector include-s---in optional tamper-resistant fea-
ture that prevents its removal from the base without the
use of a tool.
To make the detector tamper-resistant, remove the smaller
tab by breaking it at the scribed line on the tamper-
resistant tab before installing the detector (see Figure 3).
The tamper-resistant tab is on the detector mounting base.
To remove a tamper-resistant detector from the base, use a
pocket screwdriver, or similar tool, to depress the tamper-
resistant tab and turn the detector counterclockwise. The
tab is accessible through the slot on the mounting base
The tamper-resistance feature can be defeated by breaking
and removing the plastic lever from the base. However,
this permanently disables the tamper-resistance feature.
