Setting of DIP switches
DIP switch 1-2
The length of time that the door opener relay is energized after an authorized card was read and/or
the external door strike key was activated is set using the DIP switches 1-2.
DIP switch 3-4
The monitoring time is set using the DIP switches 3-4. If the monitoring contact is still open on expiry
of the monitoring time, the alarm relay is actuated.
If the monitoring contact does not require evaluating, select the position “None”.
DIP switch 5-8
The DIP switches 5-8 must be set at "0". They are only switched for creating the programming card
set.
1 = Switch ON
0 = Switch OFF
After altering the DIP switches, the operating voltage must be interrupted
briefly, as the ACC 50 only reads in the DIP switch position after the operating
voltage has been applied.
