System overview RADION contact SM provides a magnetic reed switch contact for monitoring doors and windows.

The internal reed contact is activated by an external magnet assembly which can be placed on either side of the transmitter. It also has a built-in wall and cover tamper switch that transmits a tamper signal when someone removes the device from its base or pulls away from the wall. Functions Reed Contacts There is a reed contact on either side of the device, so the magnet assembly can be mounted within 20 mm (0.78 in) of the device on either side. When the distance between the magnet and the internal reed switch of the contact exceeds 20 mm (0.78 in), an alarm signal is sent to the receiver, and from there, to the compatible control panel.
