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 functions 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.
