Access controller and alarm control unit
Dry contacts are connected to Output IN so in TTLock app you can check if the door is open
or closed.
Output short-circuit from GND means that the door is closed.
Opening- the door is open.
Output OUT is used for connection with alarm signaller or control unit. After a front panel of
the controller is disassembled an anti-sabotage button is released. The alarm is set off and the
output state is set to high. In order to connect the signaller use a relay for controlling the
device. You can also connect the alarm control unit and set the action in case of burglary.
