Two-Zone Remote Keypad Burglar Alarm Control Center
(490-0451)                 Operation                  Faxback Doc. # 33424

OPERATING THE SYSTEM

NOTE:  If you installed one or more Cat. No. 490-0484 remote keypads in the
alarm system, also see "Using a 490-0484 Keypad With the Alarm Center" on
Faxback Doc.  # 33427.

ARMING THE SYSTEM

To arm the system, use any connected keypad to enter the pass code while
the system is disarmed.

If you enter the correct pass code and there are no violated or faulted
zones, the ARM indicator on the keypad lights, and the alarm system is
armed.  If you enter the wrong pass code, the system does not arm.

NOTES:  While entering the pass code, if you enter an incorrect digit
        before entering the last digit, you can press # to cancel your
        previous entries, then enter the pass code again.

        If you enter the wrong pass code three times in a row, the alarm
        center locks out all connected keypads for 1 minute.  This prevents
        an intruder from easily determining your pass code by trying random
        combinations.

        When you use a connected keypad, all other keypads are locked out
        for 10 seconds after the last keypress.

DISARMING THE SYSTEM

To disarm the system, use any connected keypad to enter the pass code while
the system is armed.

If you enter the correct pass code, the ARM indicator on the keypad turns
off, and the alarm system is disarmed.  If you enter the wrong pass code,
the system remains, but gives no indication a wrong code was entered.
(The 490-0484 keypad does give an indication when you disarm the system.
See "Using a 490-0484 Keypad with the Alarm Center" on Faxback
Doc.  # 33427).

If the alarm system was violated while it was armed and the alarm sounded,
the ARM indicators on the keypad and the alarm center flash to show that
the alarm had sounded.  To stop the ARM indicators from flashing, press #.

SOUNDING A PANIC ALARM

You can activate the alarm system's panic alarm at any time, even if the
system is not armed.

To sound a panic alarm, press any installed panic button (if you installed
a panic/tamper zone) or press * and # at the same time on any remote keypad
(except the 490-0484 keypad, see "Using a 490-0484 keypad with the Alarm
Center" on Faxback Doc.  # 33427).  The alarm sounds and the system
automatically arms.

LOW POWER MODE

If the alarm system is running on battery power, the remote keypad(s) go
into a low power mode of operation after 1 minute of no keypresses or
change of status such as arming or disarming the alarm system.

The alarm system returns to the full power mode when you press a key or the
status of the alarm system changes.
