Radio reed contact 45 x 28mm Sensor for alarm systems

This radio reed contact is an extension of the OBD alarm system. The sensor can be taught-in at the control unit and programmed to 2 different alarm lines. An alarm line is always active when the system is sharpened. The 2nd alarm line can be switched off if required. This option is very useful in motorhomes. The installation effort is reduced to a minimum as no cables are laid. Simply glue the contact to the flap, roof hatch or door to be monitored - done.

If both parts are more than 3 cm apart, a radio signal is sent to the alarm system. The contact draws its operating voltage from a button cell, which should be replaced after approx. 2 years. The extremely small dimension of 45mm x 28mm allows an inconspicuous mounting and results in a multitude of application possibilities.
