General information
Door strike
The compact door code unit relay output is a potential-free changeover contact. The internal output
voltage or an external voltage supply can be utilised as switching voltage.
This means that any chosen consumer can, in principle, be actuated in this manner, provided the
following conditions are met:
A)
The consumer should be designed for
. Please note the no-load voltage
of approx. 22 V.
In addition, the consumer should be equipped with
(e.g. free-wheeling diode for inductive consumers).
B)
The relay contact rating should be observed when utilising external switching voltage:
or
Door strikes can be connected to the compact door code unit according to load current or no-load
current principles (see connection diagram).
The door strike is

Door locking security is ensured in the event of a power failure.
The door is released for all access
.
The monitoring contact of a door strike (or an other contact) can be connected as a strike or closer,
as the entrance is edge triggered.
