Jablotron DIGITAL TILT SENSOR

The CA-550 tilt detector detects movement of the car in two axes (x and y). Detection is achieved through electronic acceleration metering. The digital analysis used in this detector ensures high resistance against the false alarms. When the alarm is armed (power supply connected) the reference position of the detector is stored in the memory after which the position of the detector is continuously checked, compared and updated. If the tilt of the car is changed by more than 1°, the detector will be triggered.

Specification: Power 9 - 16V (DC) Power consumption typ.1 mA Operating temperature -40 °C to +85 °C Maximum sensitivity (for both axes) 1° (built-in digital filter) Angle of operation with max. sensitivity preservation ± 45° from reference (horizontal) position Installation position of the detector ± 15° from horizontal (both axes) Output negative pulse with a duration of 0.5 s Maximal output load 80 mA

Wiring: Red Power supply + 12V. It can be connected either permanently to +12V, or to the switching output of the alarm (where +12V is present when the alarm is armed). Black GND – connect to the original grounding of the car. White Output - if the detector is triggered the output will be connected to GND for 0.5 sec. It is short-circuit protected. The output should be connected to the external detector input of the car alarm.

Function: When the alarm is armed (power supply connected) the reference position of the detector will be stored in the memory (max 30 seconds). The position of the detector is continuously checked, compared and updated. If the tilt changes by more then 1°, the output will be switched to ground for 0.5 sec. Default parameters are re-set after detector activation. A built-in digital filter ensures that the detector will not be triggered by a short tilt of the car, caused, for example, by sudden burst of wind after which the car will return to its original position.
