Installing Specific Devices
This portion of the manual deals directly with
physical and electrical matters concerning the
installation of the different devices-warnings,
space requirements, physical orientation, setting
switches, connecting wires, integrating the device
into the system, and specific requirements
affecting the various approval agencies.
You should have pulled the required wiring and
verified that any wireless communication will
operate without fault. You may have programmed
the system before installation, or you may do it
near the end of the installation process (before
connecting phone line and sirens).
Figures 2-4 and 2-5 show all terminal strip con-
nections within the cabinet, indicating where all
external wiring connects.
If you connect all of the remote wiring to the
system terminals before installing the main board,
be very careful, since finding a wiring error is
likely to be difficult. Always adhere to state and
local codes, and meet any agency requirements
for any required agency approvals.
Telephone
Jack
Obtain and install an
RJ31X
(or
RJ38X),
or two of
them for 2-line service, in an appropriate place
before the line reaches any telephones, so that
the system can seize the line when it needs to call
the monitoring service.
Refer to Figures 2-4 and 2-5 for connector loca-
tion (if two lines are used, the two-line switcher will
be required-see page 2-l 7).
If the system is to be configured only for local
alarm, and remote programming will never be
used, phone connections may be ignored.

The residential cabinet box may be surface- or
flush- mounted (will not fit between 16” studs). An
optional cabinet is required for commercial UL
applications; it cannot be fully flush mounted
since the door extends around the side of the
cabinet
1/2
inch.
For UL Listing, commercial enclosures must also:
