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 in the back of this manual for instructions on wiring the KEY 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 the battery charging voltage is out of
adjustment, contact your service representative.
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 deep discharging.

Telephone Line Wiring

For proper operation, there must be no other telephone equipment connected between the control
panel and the telephone company's facilities. Also, do not use this equipment on a telephone line
equipped with "call holding" features as the tones generated by these features may interfere with
communicator operation.
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. This
may result in incomplete transmissions from the alarm panel communicator.
