Mounting Bracket
All 5600 series detectors are equipped with a
mounting bracket that includes mounting slots
to accommodate single-gang, 3

˝ octagonal, and
4˝ octagonal electrical boxes, as well as 4˝ square
boxes equipped with a plaster ring (Figure 1). The
mounting bracket is reversible to accommodate
flush-mount and surface–mount installations (Fig-
ure 2).

Wiring Installation Guidelines
All wiring must be installed in compliance with the
National Electrical Code, applicable state and local
codes, and any special requirements of the local
Authority Having Jurisdiction. Proper wire gauges
should be used. The conductors used to connect
heat detectors to the alarm control panel and ac-
cessory 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.

Flush–mount
The non-polarized screw terminals on the back of
the detector will accept 14–22 AWG wire. For best
system performance, all wiring should be installed
in separate grounded conduit; do not mix fire alarm
system wiring in the same conduit as any other
electrical wiring. Twisted pair may be used to pro-
vide additional protection against extraneous elec-
trical interference.
Wire connections are made by stripping approxi-

wire, inserting it into the proper base terminal, and
tightening the screw to secure the wire in place.
