Digital Key Switch  (490-0535A) Operation and Testing  Faxback Doc. # 6865

IMPORTANT

To prevent false alarms when testing your system, be sure to disconnect
security dialers or any other devices that send a message to a remote
location.  It is also a good ideal to temporarily replace bells or other
sounding devices with a 12-volt bulb that draws less than 1 amp.

Note:  Check the system once a week to be sure it continues to operate and
       refer to the main control unit operation instructions for proper
       test procedures.

SETTING YOUR SECURITY CODE

When power is first connected to the Digital Key Switch, the preset
factory security code will be in effect.  This code is [1 2 3 4 ].

1.  Press [*].

2.  Enter the current security code-the preset factory code ([1 2 3 4 ])
    or any code you have previously selected.

3.  Press [*] again.

4.  Enter your personal code-the code may be any four digits; you may
    repeat a digit as many times as you like, [3 5 6 4], [5 5 5 9], or
    [9 8 2 2 ].

Note:  We suggest you avoid obvious numbers such as your street address,
       birth date, etc.  Also, it is a good ideal to periodically change
       your code.

5.  Press [*] a final time to complete the code entry.

Notes  If you take more than 10 seconds to complete step 2, 3, or 4, the
       Digital Key Switch will automatically reset to the old code.  You
       must begin again with step 1.

       If you make an error before completing step 5, press [#] (clear)
       and begin again with step 1.

       If you realize you made a mistake in the new number after
       completing all steps, you must repeat the process using the
       incorrect code number in step 4.

       If you do not know, or remember, the code number, temporarily
       disconnect power from the Digital Key Switch.  This will reset
       the code to the factory code number ([1 2 3 4 ]).  Then begin with
       step 1.

IMPORTANT!

ONLY PRESS [*] WHEN CHANGING YOUR SECURITY CODE.  [*] IS NOT REQUIRED FOR
NORMAL OPERATION.

ARMING/DISARMING THE ALARM SYSTEM

1.  After your code is selected, enter the number to arm the system, the
    ARM LED indicator should light (if such connections were made during
    installation).

Note:  If the action of the ARM LED is reversed (the indicator lights when
       the system is disarmed), you have probably used wrong REMOTE
       Normally Open/Normally Closed terminals.  Change the connections
       and try again.

2.  Trip the alarm and confirm that it is, in fact, armed.

3.  Enter your code again to disarm the system.

If the Digital Key Switch does not respond to your code, it is possible
that there was a power failure while you were away or that there is a
loose, "intermittent" connection at the POWER terminals.  In either case,
the Digital Key Switch will reset to the factory code ([1 2 3 4])
when power is restored.

IMPORTANT!

IF YOU HAVE ENTERED AN INCORRECT CODE, YOU MUST WAIT 10 SECONDS TO TRY
TO RE-ENTER THE CORRECT CODE.

ARM AND LOOP INDICATORS

The operation of these indicators will vary depending on the type of alarm
system you use.  Some system will use both indicators; others might use
only one or neither.

In most cases, these indicators should respond in the same way as
corresponding indicators on the main alarm unit.

If connections are made and the indicators do not work, check for loose
connections, incorrect polarity, etc.

PANIC CIRCUIT

If the PANIC terminals on the Digital Key Switch are connected to a 24-
hour panic/tamper loop on your alarm system, simultaneous pressing of
[#] and [*] should trip the alarm at any time, whether or not the system
is armed.

On some alarm systems (49-450A, for example) you can reset the alarm by
entering your code at the Digital Key Switch.  If this does not work,
you will have to reset it at the main alarm unit.
