Siemens K44 Manuel D’Utilisation

K44 Duo is equipped with an output that can be activated 
for one of the following reasons:

A user enters a duress code
OR 
The door held warning time expires or the door is 
forced open

Choose which alternative to use. Then connect e.g. a bur-
glar alarm or similar to the output.

To make entrance easier, e.g. during office hours, connect 
an external contact. Then use the contact to activate or 
deactivate zero opening, i.e. opening the door by pressing 
the zero button on the keypad. Note that this is only applies 
to relay output 1.

If the Toggle function is activated, the code can be used to 
unlock the door. The door remains open until a valid code is 
entered once again (see the Toggle on/off section). 

If needed, a door bell can be connected to K44 Duo. To ring 
the bell, the visitor presses the button labelled with a bell 
on the code lock’s keypad.
