WS-688-01—Digital vibration sensor detector, adopting the international advanced photoelectric vibration sensing principle, integrating vibration sensor and vibration analyzer, with CPU processing technology, suitable for various types of ATM automatic teller machines and different sizes Preventing equipment such as safes, etc., effectively prevent the occurrence of destructive behaviors such as smashing, drilling, and prying of equipment. WS-688-01 is a normally closed output, which can be used with all brands of wired alarm hosts. It can also be used with hard disk video recorders and matrix controllers. The sensitivity of the detector can be double-adjusted, and it has a vibration accumulation alarm effect, which effectively prevents the occurrence of false alarms. This product is small in size, simple to install, stable in performance, and widely used. It has been used for the prevention of ATM automatic teller machines and other equipment in major banks across the country.
WS-688-01 digital vibration detector, equipped with microprocessor control, alarm trigger can be achieved by a single vibration amplitude, or by accumulating multiple vibration signal bombs of different sizes within a time limit. The weak vibration signal is shielded, and will not accumulate to generate an alarm. Only strong vibration or multiple vibrations will be considered as a valid signal and will be stored in the pulse count memory. At the same time, it can manually set the sensitivity to ensure that an optimal operating point can be set according to the environmental conditions-to prevent false alarms without reducing the sensitivity.

Sensitivity adjustment:
Turn the sensitivity potentiometer counterclockwise to the end (S1 jumper cap disconnected), the sensitivity is the lowest at this time, slowly turn the VR clockwise to increase the sensitivity, at each sensitivity set point, hit the protected surface (simulation attack Strength), pay attention to whether the red light is on. For example, if the red light is on, it means an alarm has occurred, and this sensitivity point is the correct set point. Try tapping with a smaller intensity to test that the sensitivity is too high. (Close the S1 route cap and turn it clockwise to the end, sometimes the sensitivity is highest)
