Siemens K44 User Manual

The K44 Duo allows for either using duress or alert. 
The same command is used for different function.
Duress
With the Duress function activated, a user can enter 
a special code if he or she is forced to open the door 
under threat. It is important to have a plan for what 
action to take when a duress code is entered.
NoTE!  If Duress is activated, make sure you have not 

programmed codes with consecutive digits. 
Code 1234 must not exist with codes 1235 and 
1233. Code 5679 must not exist with codes 
5670 and 5678.

The Enter duress code section describes how a user 
should enter the duress code.
Alert
When K44 Duo is delivered, the alarm output is set 
to be activated if the door is open too long or if the 
door is forced open. 
Note that door contacts must be connected and that 
Door monitoring must be activated for this to work.
