How to Initiate Silent Duress Alarm in Auditcon Models 252 & 552?

Answer 

This operation is only available if the silent duress alarm feature is installed on your lock and you have purchased and installed an Alarm Interface Kit (P/N 301040). 

The silent duress combination is created by taking your existing combination and adding 10 to the last two digits of the PIN. For example, if the PIN is “526674”, entering “526684” will activate the silent duress alarm. If the PIN is “526694”, entering “526604” will activate the alarm. In this case note that “9” becomes “0” and that the “6” remains unchanged (i.e., no digits are carried over and added to the “6”).

 The silent duress alarm is activated and normal lock operation continues.
