K44 Duo Installation & User manual

What is K44 Duo?

K44 Duo is a compact code lock with two relay outputs. This makes K44 Duo capable of controlling two doors – or one door and an optional function, e.g. a light switch. Either

a four- or a six-digit code can be used to open connected doors. All programming is done from the keypad.

Open two doors using one code

The advantage of using two relay outputs is that two func- tions can be activated at the same time, using only one code. For example, the code can open the lock and turn on a light switch at the same time.

Another setup is to connect the code lock to two doors. One code is programmed to operate both doors, while the other only opens one of the doors.

If the code is programmed to open both doors, you can set K44 Duo so that the other door does not open until the first door has been opened and closed (see the Delay section).

For each code, choose whether to activate both relay outputs, only one or only the other.

Disable the codes whenever needed

K44 Duo offers the possibility to disable codes at certain times. For example, the cleaning staff’s access to the build- ing can be limited to certain hours, while tenants/staff can have access to the door 24 hours a day.

By connecting two time clocks to K44 Duo, three different time zones can be used to control the codes: one controlled by time clock 1, one controlled by time clock 2 and one that is valid 24 hours a day, i.e. no time control.
