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.

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 12 VDC. See the 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.

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.

The wiring table gives the wire run length from the control

panel to the keypad for various gauges of wire. Wire run

lengths are based on the maximum current drawn by the

keypad. (All lights ON).

If two wires of the same gauge are paralleled, the run length

can be doubled. eg. If 8 #22 AWG wires are used, 2 red, 2

blk, 2 grn and 2 yel, the run length would go from 420’ to 840’

(127 to 254 m).

Wire run distances are in feet/meters from the control panel

to the last device on the loop. Calculations are based on 12

VDC at the panel with a maximum 10% voltage drop at the

last device. Observe polarity when connecting siren drivers,

sirens and polarized bells.
