AXIS A1601 Network Door Controller
Specifications
Configurable (Input or Output)
Important
The recommended maximum cable length is 100 m (328 ft).
Supervised inputs
To use supervised inputs, install end of line resistors according to the diagram below.
UL: Supervised inputs were not evaluated by UL for burglary use. Only door monitor and REX support supervision with end of
line resistors.
Note
It is recommended to use twisted and shielded cables. Connect shielding to 0 V DC.
Door connector
Two 4-pin terminal blocks for door monitoring devices (digital input).
Only door monitor supports supervision with end of line resistors. If the connection is interrupted, an alarm is triggered. To use
supervised inputs, install end of line resistors. Use the connection diagram for supervised inputs. See page 38.
