Outdoor Telecom Cabinet Shock Sensor 12VDC Digital Vibration Detector
With Alarm Relay Output And Microprocessor Control
Model: EA8016001
Function
The digital vibration inductive detector, equipped with microprocessor control, alarm triggering can be achieved by a single vibration amplitude, or by accumulating multiple vibration signals of different sizes within the time limit. The weak vibration signal will be shielded, but not accumulated to generate alarm. Only strong vibration or multiple times vibration will be considered as effective signal and stored in pulse counting memory. At the same time, it can set the sensitivity manually to ensure that the best working point can be set according to the environmental conditions - to prevent false alarm without reducing the sensitivity.
Wiring
Power terminal connected to 12V DC power supply
Alarm output connected to normally closed zone of alarm host
Anti disassembly output connected to normally closed zone of alarm host
Adjust sensitivity
First, turn the sensitivity potentiometer anticlockwise to the end. At this time, the sensitivity is the lowest. Slowly rotate VR clockwise to increase the sensitivity. Knock the protected surface (simulated attack force) at each sensitivity setting point, and pay attention to whether notice if the red light is on. If the red light is on for two seconds, it indicates an alarm. This sensitivity point is the correct setting point, and then try again knock with less force to test whether the sensitivity is too high.
The jumper cap on the circuit board of the detector is a high and low sensitivity regulator, which is high sensitivity when closing and low sensitivity when opening.

Fixing and installation
Disassembly and combined installation
1. Remove the panel
Insert a small paper cutter or screwdriver to the gap beside the screw cover (see Figure 1), gently pry up the screw cover, loosen the screw, and then separate the surface cover and the bottom cover (see Figure 2)
2. Combination cover
Place the screw in the screw pit, then tighten the screw and carefully close the cover.
3. Installation
Fix the vibration detector to the protected surface.
