Installation instructions / ACS-2 plus
15.4 Connecting a door strike
15.4.1 Connecting a fail secure door strike
Fail secure door strike = strike with load current function: The door is released if the coil is
energized
Tamper monitoring for the strike with load current function is possible. For this, a DC door strike must be
connected as shown above.
This function is not possible with a no-load current door strike and a door strike supplied with alternating
voltage or supplied by an external voltage source - not by the voltage source which supplies the ACS-2 plus.
The tamper monitoring for "door strike 1" and "door strike 2" must be deactivated (otherwise a board failure
of the ACS-2 plus is caused).
ACS-2 plus terminal assignment:
With tamper monitoring
for relay 1:
jumper ST6 = 4 - 6
for relay 2:
jumper ST6 = 3 - 5
Without tamper monitoring (= standard)
for relay 1:
jumper ST6 = 2 -4
for relay 2:
jumper ST6 = 1 - 3
