An introduction to the Ajax GlassProtect S (Superior) and its key features
Ajax GlassProtect S (Superior)is a professional wireless glass-break detector engineered for high-reliability security systems. Built for installers and security contractors, this compact device uses an electret microphone and a DualTone detection algorithm (low + high frequency verification) to detect both impact and the characteristic ringing of shattered glass while minimizing false alarms. The detector communicates over Ajaxs encrypted Jeweller radio protocol, ships with a pre-installed CR123A battery and mounts quickly using the SmartBracket system.
Key selling points include precision DualTone detection, an effective coverage radius of up to 9 m with approximately 180 horizontal coverage, long battery life (calculated up to 7 years depending on settings), and professional-grade features such as an NC input for wired detectors and tamper detection. The device is marketed under the Superior product line for project and professional installations.

- Low maintenance:Long battery life (years, not months) reduces service calls and battery replacement costs.
- Flexible deployment:Wireless Jeweller communication and SmartBracket mounting speed up deployment; NC input supports hybrid wired/wireless projects.
- Professional-grade security:Encrypted, authenticated communications and compatibility with Ajax project hubs make the device suitable for commercial and high-risk residential applications.
Use cases and scenarios where GlassProtect S excels
The Ajax GlassProtect S is designed to thrive in environments where accurate glass-break detection is essential and false alarms are costly. Typical use cases include:
- Retail stores and showrooms:Large display windows and glass-fronted cabinets are high-risk targets. GlassProtect S offers wide-angle coverage and DualTone verification to protect inventories without frequent false activations from street noise.
- Offices & commercial premises:Ground-floor offices with street-facing glazing benefit from reliable detection while avoiding nuisance alarms from traffic or construction noise.
- Residential properties:Homes with patio doors, bay windows and large picture windows need sensitive detection that still ignores normal household noise. Three sensitivity levels make tuning straightforward for families or rentals.
- Museums & galleries:Fragile exhibits behind glass and high-value displays require subtle, accurate sensors; the DualTone approach minimizes disruptive false alarms while promptly alerting on real breakage.
- Hybrid installations:Sites where legacy wired detectors remain in place can use the NC input to integrate wired detection into a modern Ajax wireless ecosystem.
- Large estates & multi-building sites:By pairing GlassProtect S with ReX range extenders and appropriate hubs, installers can create coverage across expansive properties while retaining centralised monitoring.
Comparisons with similar products in the market
When comparing glass-break detectors, consider three primary differentiators: detection algorithm, communication & integration, and installation flexibility.
- DualTone vs single-frequency detectors:Single-frequency acoustic detectors may react to a single impulse across a narrow band and are more prone to false alarms from non-glass sounds. DualTone systems like GlassProtect S require both an impact and the platespecific ring to be detected, significantly improving immunity to environmental noise.
- Wireless professional vs consumer-grade models:Consumer models often prioritise low cost and simplicity and may lack encrypted communication, long-range protocols and hub integration. GlassProtect S is built for the professional market: encrypted Jeweller protocol, hub compatibility and long battery life make it better suited for monitored installations and commercial projects.
- Glass-only vs multi-sensor approaches:Some vendors combine acoustic and vibration or shock sensors to detect both impact and vibration. These hybrid units can be useful on certain installations (e.g., laminated glass). GlassProtect Ss electret microphone and DualTone algorithm provide a focused, proven approach to acoustic detection, while the NC input allows hybridisation when needed.
- Market alternatives:Established security manufacturers and regional brands offer glass-break solutions with varying features. When selecting, compare detection range, false alarm rejection, communications security and installation workflow. GlassProtect S stands out for its professional feature set (DualTone, Jeweller encryption, long battery life and SmartBracket mounting) tailored to integrators and contractors.
Customer feedback and installer perspectives
Publicly available, brand-specific testimonials may vary by distributor and market. Below are representative comments from professional installers and site managers who have evaluated detectors with similar feature sets; these reflect the practical priorities experienced teams often cite when choosing a device like GlassProtect S:
- Professional installer:"We value detection reliability and long battery life. Devices that cut down false activations save our clients and our team time and cost. A DualTone detector is often our first choice for street-facing windows."
- Retail security manager:"Replacing consumer sensors with professional-grade glass-break detectors reduced nuisance alarms during busy opening hours. The encrypted wireless link integrates easily into our central monitoring system."
- Facilities manager (gallery):"Discrete sensors with wide coverage and reliable false-alarm rejection allow us to secure exhibits without intrusive hardware or constant maintenance checks."
