(4 Pcs)Indoor Glass Broken Sensor Wired Vibration Detector PA-456 Home security Alarm NC output relay alarm system accessories |

Functions:
1. Mollusk drive, digital signal process 8/12 bit microprocessor (8MHZ).
2. High frequency sound pressure detection.
3. All sound frequency 7 kinds frequency signal and impact analysis include inferior sound press analysis.
4. Digital filtration RFI/EMI rejection.
5. Particular mike design.
6. Adjust the sensitivity by hand can avoid the false alarm.
Choose the installation place:
The right place is the key element to the detector.
It can install on the ceiling, near the glass and opposite the glass, forbid installation the things which have noice such as bell, fan, compressor and machine.
Make the mike be opposite to the glass with no obstruction and in the best angle. Don\'t install

2) Connect the Transformer.
3) Adjust the sensitivity
4) Check the detector
Adjust the sensitivity
The detector with the perticular yellow LED, when the noice is up to the alarm level, the yellow
LED will flash, which means adjust the sensitivity to the low level. The setting method as follow:
Use a plastic ruler to flap the glass, then the yellow LED will be light, but the red light will
not. If the red LED is bright, it means the sensitivity is too strong, you revolve VR cathode to

night, when set it please put down the curtain. Notice: Don\'t adjust the sensitivity too high in
case of false alarm.
Test by glass frequency rate:
Take the tested glass in the far place, press “ PUSH” to enable to have glass broken frequency.The red LED lights, if not, please adjust the sensitivity in high position.(revolve VR cathode clockwise)
