Notes
The extension terminal forms a closed loop with the device
connected to it. when the loop is opened (the device is triggered),
the door contact is activated.
The device connected to the extension terminal is in series with
the internal magnet switch: both can work together
simultaneously.
You can choose to use the extension terminal alone with the
internal magnet switch bypassed or to use both together.
If both the internal magnet switch and extension terminal operate
together, then:
o When the protected door is opened/closed or the external
device is triggered, the door contact activates and transmits a
signal immediately.
o However, the door contact will only transmit a (door closed) or
(restored signal) after the protected door and the external
device are restored for 3 seconds.
