20-PIN distributor adapter cable wiring harness plug & play for VW Audi Seat factory radios
VAT plus ShipmentItem description
Original Alpine glass break sensor with very high false alarm security
A hidden microphone analyzes the frequency, intensity and timing of all sounds in the vehicle. The spectral properties of a recorded sound are evaluated by a microprocessor. If typical characteristics of the bursting noise of glass are detected, an alarm is triggered. This technology works absolutely without false alarms!
Inexpensive sensor
Easy installation
Minimal wiring costs
Very high false alarm security
Important NOTE:
If you want to connect multiple alarm sensors to one alarm input on the alarm system, you must decouple each alarm line with a blocking diode (sold separately). Otherwise false alarms may occur.
Red: Connect the red wire of the 3-pin plug to permanent 12V
Blue: Connect the blue cable of the 3-pin plug to the (-) alarm input of your alarm system
Choose a good installation location, e.g. B. under the headliner or opposite the window to be monitored, for optimal function of the sensor. Avoid proximity to loud motors, compressors or fans. Determine the exact position and orientation of the glass breakage sensor so that the microphone side of the sensor has an unobstructed view of the monitored windows. No objects or wiring harnesses may obscure the detection angle of the sensor.
