Specifications: Ajax Glassprotect - White SMART
| SKU | 7185 |

The white Ajax GlassProtect is a compact, wireless glass break sensor specifically designed for early detection of break-ins through windows. The sensor is battery-powered and immediately sends a notification to the Ajax SMART alarm system upon detection. Thanks to intelligent sound analysis, the GlassProtect distinguishes actual glass breakage from ambient noise, significantly reducing false alarms.
The sensor is suitable for homes, shops and business premises where windows, glass doors or display cases require additional protection against impact.
Glass breakage detection with dual analysis
The Ajax GlassProtect uses a sensitive microphone that analyzes two sound signatures. First, it recognizes the low-frequency sound of a blow or impact, followed by the high-frequency sound of breaking glass. Only when both signals are detected in the correct sequence does the sensor send an alarm.
This dual detection prevents normal sounds such as thunder, barking dogs or traffic from triggering an alarm.
Reach and placement
The glass break sensor can detect broken glass up to a distance of approximately 9 meters. For reliable operation, you typically mount the GlassProtect on a wall or ceiling, pointing it at the window or glass surface you want to protect. The sensor doesn't need to be mounted directly on the window and also works on single- or double-glazed windows.
It's important that the sensor listens freely to the glass and isn't obscured by curtains or heavy objects. In the Ajax app, you can use the sensitivity and test functions to check placement.
Always-on security
The Ajax GlassProtect is designed for continuous monitoring. Glass breakage can occur even when the alarm system is not active, so the sensor remains alert and sends an immediate notification as soon as glass breakage is detected.
Wireless communication and security
The sensor communicates wirelessly with the Ajax Hub via the secure Jeweller protocol. The connection is encrypted and continuously monitored for interference and tampering. This ensures reliable operation, even over long distances.

Frequently asked questions about the Ajax GlassProtect
What exactly does Ajax GlassProtect detect?
GlassProtect detects glass breakage by analyzing both the impact on the glass and the sound of breaking glass. Only when both signals are recognized will an alarm be triggered.
Does the sensor go off when there are thunderstorms or dogs?
No, thanks to the double sound analysis, GlassProtect ignores sounds such as thunder, barking dogs and traffic noise outside the window.
How far from the window can I install GlassProtect?
The sensor can detect glass breakage up to approximately 9 meters away. Ideally, position the sensor facing the window, with no obstacles blocking the sound.
Does the Ajax GlassProtect also work when the alarm system is not armed?
Yes, the glass break sensor is designed for continuous monitoring and also sends a notification when the alarm system is not active.
How long does the GlassProtect battery last?
The CR123A battery has a lifespan of up to approximately 7 years, depending on usage and settings. You'll receive a prompt notification via the Ajax app when a replacement is needed.
