Installation

Mounting the Panel

Select a dry location close to an unswitched AC source and close
to the telephone line connection. Remove the printed circuit board,
the mounting hardware and the keypad from the cardboard retainer
inside the cabinet. Before attaching the cabinet to the wall, press
the four white nylon printed circuit board mounting studs into the
cabinet from the back. Once the cabinet is mounted to the wall, pull
all the cables into the cabinet and prepare them for connection. Use
a meter to test the wiring for opens, shorts and grounds. Press the
circuit board onto the white nylon mounting studs. Complete all
wiring to the control panel before applying AC power or connecting
the battery. Do not plug the transformer into an outlet that is
controlled by a switch.
NOTE: See Control Panel Wiring Diagram inside the back cover
for more information.

Mounting the Keypad

Keypads should be located close to the designated "Entry-Exit"
door(s) and mounted at a height convenient for all users.
NOTE: Complete all wiring to the control panel before applying AC
power or connecting the battery.
Auxiliary Power
Connection
The auxiliary power supply can be used
to power keypads, motion detectors and
other devices that require 11 V
Fire Zone Wiring section for the
connection of 4-wire smoke detectors.
The total load for the auxiliary power
output must be calculated for all devices
connected across the AUX +/- terminals
and for devices connected between the
AUX + and PGM terminals. The output
current cannot exceed 475 mA. Allow 35
mA for each PC1500RK keypad
connected to the panel.

PGM Terminal Connections

The PGM terminal is a switched negative output which can be
controlled by various programming options (See Programming
Guide section [24]). Devices controlled by the PGM output must be
connected between the PGM terminal, which is (-) and the Aux. (+)
terminal.

Bell/Siren Connection

Observe polarity when connecting siren drivers, sirens and polarized
bells.

Keypad Wiring

Up to three keypads may be connected in parallel. Do not connect
multiple keypads on the same keypad wire run. For Standby
Loading purposes, use a current draw of 35 mA per keypad. This
represents the panel in the disarmed state with two zones open.

Fire Zone Wiring

Any one of the 6 zones may be programmed as a Fire Loop. See
Programming Guide section [11].
Smoke detectors should be the latching type and have Normally
Open (N.O.) alarm initiating contacts. Power wiring from the AUX +
/ PGM terminals should be supervised using an RM-1 relay after the
last smoke detector. The RM-1 N.O. contacts (closed with power
applied) should be wired in series with the alarm initiating end-of-
line resistor so that should power to the detector(s) fail, a fire loop
trouble will be initiated.

Burglary Zone Wiring

Burglary zone definition, (eg. Delay, Instant, 24 Hr. etc.) is
programmed via the keypad. See the Programming Guide, section
[11].

Battery Connection

If the battery is reverse connected, the 5 A fuse will blow. The
battery charging voltage is factory set and normally needs no
adjustment. If the battery charging voltage is out of adjustment,
contact your service representative.
If AC power is OFF and the battery voltage is approximately 9.5V or
lower, the battery will be disconnected and the panel will power
down. To power up again, the AC will have to be re-established.

Telephone Line Wiring

NOTE: Ensure that plugs and jacks meet the dimension, tolerance
and metallic plating requirements of 47 C.F.R. Part 68,
Subpart F.
WARNING
FCC restricts using this equipment on certain types of telephone
lines. Also, do not use this equipment on a telephone line equipped
with a "call holding" feature, as the tone generated may interfere
with the communicator operations.
Do not connect the alarm panel communicator to telephone
lines intended for use with facsimile (FAX) machines. These
lines may incorporate a voice filter which disconnects the line
if other than FAX signals are detected, resulting in incomplete
transmissions.
