Wiring

NOTE: Complete all wiring to the control panel before applying battery or AC power.

Burglary Zone Wiring

Burglary zone definition, (for example, Delay, Instant, 24-Hour, and so on) is programmed using the keypad.
Refer to Programming Guide Section [1].

Auxiliary Power Connection

The Auxiliary Power Supply can be used to power motion detectors and other devices that require 12 V
total load for the Auxiliary Power Supply 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
800 mA.

PGM Terminal Connections

The PGM terminal is a switched negative output which can be controlled by various programming options; refer
to Programming Guide Section [4]. Devices controlled by the PGM output must be connected between the PGM
terminal and the AUX+ terminal.

AC Power Wiring

Complete all wiring to the control panel before connecting AC power or the battery. The transformer should
not be connected to an outlet that is controlled by a switch.

Battery Connection

If the battery is connected in reverse, the 5 A battery fuse will open and will need to be replaced. The battery
charging voltage is factory set and normally needs no adjustment.
If AC power is OFF and the battery voltage drops to approximately 9.5 V or lower, the battery will be automatically
disconnected and the panel will power down. To power up again, AC power will have to be re-established. This
feature is designed to prevent damage to the battery due to prolonged discharging.

KEY Terminal Connection

The KEY terminal may be programmed for keyswitch operation or for use as a tamper zone. Refer to the
Hook-up Diagram for instructions on wiring the KEY terminal.
