The wireless door/window contact secures your windows and doors against unauthorized opening. The window/door contact consists of a sensor and a magnet. If the magnet is separated from the sensor, an alarm is triggered. You can also use the sensor as a doorbell (Q Series) - when the door is opened you hear an acoustic signal.

The Blaupunkt wireless door/window contact repels intruders.
With door/window sensors (DC-S4) you ensure optimal surveillance. This ensures that burglars cannot even enter the house unnoticed. Security with door/window contacts is therefore particularly important and superior to security with motion detectors. The material of the compact sensor is of high quality, the design modern and simple - it fits perfectly into your room. If the distance between the magnet and the sensor increases due to forced opening, the armed detector activates an alarm. You can act immediately at any time, because you are also notified on your mobile phone via SMS or voice message. The built-in tamper contact protects the sensor against manipulation. If someone tries to remove the sensor without permission, an alarm is also triggered.
