Wired Glass Break Sensor — Smart Home Security Detection
Upgrade your home or business security with this high-sensitivity wired glass break sensor. Designed to instantly detect the distinct frequency of breaking glass, this compact detector sends an immediate signal to your alarm system's main unit — giving you fast, reliable protection for windows and glass doors of any size.
⚠️ Important: This wired glass break sensor must be used in conjunction with a compatible wired alarm system main unit. It does not operate as a standalone alarm.
Key Features
- Advanced Digital Signal Processing: 8/12-bit microprocessor running at 8MHz precisely distinguishes glass-breaking frequencies from everyday sounds.
- Pet-Immune Technology: 7-frequency digital filters prevent false triggers from pet movements, ambient noise, or other non-glass sounds outside its detection range.
- Adjustable Sensitivity & Coverage: Set to high for up to 9 meters (30 ft) of coverage, or lower for up to 4.5 meters (15 ft) — ideal for various room sizes.
- Flexible Installation: Mount on ceiling or wall near windows. Covers windows of any size.
- High Immunity to Interference: Built-in RFI and EMI shielding ensures consistent, dependable performance.
- Visual Status Indicators: Green LED glows during active detection; Red LED flashes for 3 seconds upon triggering an alarm event.
- Tamper-Resistant Design: Normally-closed tamper switch signals if the cover is removed, adding an extra layer of security.

Frequently Asked Questions
Q: Does this wired glass break sensor work as a standalone alarm?
A: No. This glass break sensor is designed to work as part of a wired alarm system. When it detects the frequency of breaking glass, it sends a signal to your alarm system's main unit, which then triggers the alarm. You must have a compatible wired alarm panel for it to function.
Q: What is the maximum detection range of this glass break sensor?
A: When sensitivity is set to high and the sensor is installed on the ceiling or a high wall position near the window, coverage extends up to 9 meters (approximately 30 feet). At a lower sensitivity setting, the range is up to 4.5 meters (approximately 15 feet).
Q: Will this sensor trigger false alarms from pets or loud music?
A: No. The 8MHz digital processor uses 7-frequency digital filters to specifically identify the unique acoustic signature of breaking glass. Sounds from pets, music, traffic, or other everyday sources outside that specific frequency range will not trigger the sensor.
Q: Where should I install this wired glass break detector?
A: For best results, mount the sensor on the ceiling or on a wall close to the windows you want to protect. The sensor covers windows of any size, and one unit can protect a broad area when set to maximum sensitivity.
