Specifications
Door connector
One 4-pin terminal block 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 .
Function
DC ground
Input
Important
The qualified cable length is up to 30 m (98.4 ft) if the following cable requirement is met: AWG 24.
Relay connector
One 4-pin terminal block for form C relays that can be used, for example, to control a lock or an interface to a gate.
Function
DC ground (GND)
NO
COM
NC
Relay power jumper
When the relay power jumper is fitted, it connects 12 V DC or 24 V DC to the relay COM pin.
It can be used to connect a lock between the GND and NO, or GND and NC pins.
Pin Notes
1, 3
2, 4
For communicating with door monitor.
Digital input or Supervised input — Connect to
pin 1 or 3 respectively to activate, or leave floating
(unconnected) to deactivate.

Notes
Normally open.
For connecting relay devices.
Connect a fail-secure lock
between NO and DC ground.
The two relay pins are
galvanically separated from
the rest of the circuitry if the
jumpers are not used.
Common
Normally closed.
For connecting relay devices.
Connect a fail-safe lock
between NC and DC ground.
The two relay pins are
galvanically separated from
the rest of the circuitry if the
jumpers are not used.
