UL: Supervised inputs were not evaluated by UL for burglary use. Only door monitor and REX
support supervision with end of line resistors.
Note
We recommend using twisted and shielded cables. Connect shielding to 0 V DC.
Door connector
Two 4-pin terminal blocks for door monitoring devices (digital input).
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 .
