3.2 Connection
To connect the blocking device you can use the armed or not armed output of a burglary alarm
center or a timely limited release signal for the entrance control applications.
When activating the input, the blocking device will close, when deactivating, the blocking device
will open.
A)
Signal behavior and example for switching on with “0 V-activated“-“armed“signal:

Illustration 3.4 - Ext. armed 0 V-active
The input of the blocking device requires very little
current – on average 3...4 µA. If the used control output
to activated the Input voltage may have a residual
current of a view µA (e.g. due to the corresponding
burglary alarm center protective circuit – varistors,
transildiods, etc) it may occur that the blocking device
will not correctly react when changing over the output
from “active“ to "inactive“. In order to work properly, a
pull-up resistance can be put between the input and
+12 V. The amount of resistance shall not exceed 1 M
Ω
.

Attention: When using a pull-up resistance the quiescent current consumption of the status
“closed” will increase according to the distribution voltage and to the used amount of
resistance!
Calculation example: U = 12V, R = 100K
I
R
= 120µA
B)
Example of switching on with “+12 V-activated”-“not armed“-signal:
When activating the input via a p-n-p transistor a
resistance needs to be put between the input and 0 V.
The amount of resistance must not exceed 33 k
Ω
