Anti / Jack Sensor

The device is based on two angular transducers. The system is controlled by a built-in microprocessor which automatically adapts to the position of the vehicle. Angular variations are analysed, and any minor disturbances (heavy vehicle vibration or wind-induced movement) are ignored. When genuine third-party intervention is detected (car being lifted or tyres deflated) the sensor outputs an earth on the trigger pin. Digital signal filtering improves sensor performance.
Advanced production techniques have allowed a high degree of miniaturisation. The device comes in the form of a relay capsule, which makes it extremely water resistant and easy to install.
SPECIFICATIONS
  • Sensitivity: 2 degrees in all directions.
  • Check range: better than ±50 degrees in all directions.
  • Reference reset : automatically adjust to what ever the rest angle is.
  • Arming delay : 60 seconds from activation, 34 seconds from one alarm to the next
  • Operating temperature: from –30 to +85 degrees Centigrade (in-car temperature)
  • Operating Voltage : 8 - 20V with protection against reverse polarity.
  • Current consumption : 3.2 mA @ 12V.
  • Output to alarm: - approximately 1 second negative pulse, protected by a 100 Ohm resistor.
  • Connections: 3x6,35 mm spade terminals (standard automotive).
  • Case construction : self-extinguishing plastic, 26x26x25 mm, with screw hole for bulkhead attachment.

N.B. for correct performance, the tilt sensor must be powered only when the alarm is armed.

STANDARDS APPROVAL

  • Manufactured in accordance with the standards UNI-EN-ISO 9002.
