Requirements of the power supply and charging unit and the battery:
1. Continuous current drain
2. Battery capacity
In this case, the following must be selected:
010690.02
018003
Larger actuators (e.g. door strikes) or devices with higher current consumption can be
supplied from external power supply units (see chapters 18.1 and 18.2: In this case, +12V
DC and 0V are connected to the external power supply unit and not to terminals 45 and 46).
If power supply failure can occur at any time (e.g. on locations occupied 24 hours
a day), then a backup time of 4 hours with 200 lock operations is recommended.
The ACS-8 is controlling one door.
The door is opened 60 times within four hours.
The door release time is 10 seconds per opening (fail secure strike).
