🔊 Precise Sound Detection to Eliminate False Alarms
🧠 Detectors typically employ a dual-technology combination, such as "acoustic sensing + vibration" or "infrasound + high-frequency sound." For instance, an alarm is triggered only when the device first detects the low-frequency vibration wave caused by an impact on the glass, followed immediately by the high-frequency sound wave of the glass shattering. This effectively filters out noises like clapping, door slamming, or clashing metal.
🎚️ Multi-scenario adaptability:
Compatibility with various materials: Adjustable settings allow for the detection of common glass types, including float glass, tempered glass, laminated glass, and coated glass.
Adjustable sensitivity: To suit the acoustic environment of different rooms, detectors usually feature multi-level or continuously adjustable sensitivity controls, balancing detection performance with interference immunity.
🔗 Reliable external integration:
⚡ Alarm signal output: Used to trigger sirens or lights, or to send signals to a central alarm control panel.
🔒 Tamper protection: If the detector housing is opened or the unit is forcibly removed from the wall, a tamper signal is immediately issued to prevent malicious interference.
🎯 Optimal installation location:
Install on the ceiling or wall facing or near the protected glass, ensuring a clear line of sight between the detector's microphone and the glass, typically within a range of 3 to 9 meters.
A single detector can protect multiple panes of glass; the ideal installation point is centrally located relative to the windows.
🚫 Areas to avoid:
Keep away from noise sources: Do not install near equipment that generates continuous or sudden noise, such as air conditioner compressors, electric bells, fans, or doorbells.
Avoid obstructions: Heavy curtains and blinds can significantly absorb sound energy. If they cannot be avoided, install the detector on the window frame or ceiling on the inner side of the curtains.
Mind the installation height: For wall mounting, a height of 2.4–3 meters is recommended; for ceiling mounting, 4–6 meters is recommended.
