Digital Key Switch  (490-0535A)      Features          Faxback Doc. # 6861

The RADIO SHACK Digital Key Switch is a high quality, UL approved security
device designed and manufactured in Tandy Corporation's own factories.
It eliminates the need to carry a key for arming/disarming your alarm
system.  Instead, you simply enter your personally selected 4-digit code.
The unit's micro-processor allows you to select from 10,000 possible
codes.

Note:  You can change the code as often as you like.

Other features available with the Digital Key Switch are:

  Selectable arm/disarm switch mode (latching or momentary).

  ARM indicator shows alarm status if your system provides connections for
  remote arm indicators.

  LOOP indicator shows perimeter loop status if your system provides
  connections for remote loop indicators.

  Panic circuit for manual activation of the alarm from the Digital Key
  Switch.

  Built-in tamper switch to prevent unauthorized entry into the switch
  box.

  Wrong number lock-out to discourage random code number entries by
  unauthorized persons.
