Scantronic DET-2R-GB | Wireless Break Glass Detector | 360° Acoustic Detection, Grade 2

FAQs

How does the 360-degree detection pattern work and where should I position the detector?

The DET-2R-GB’s 360-degree acoustic detection capability means the device monitors sound from all directions within its 6-metre detection radius, eliminating the need for precise aiming toward specific windows. This omnidirectional pattern allows the detector to be positioned centrally in a room to monitor multiple windows or glazed doors simultaneously. Optimal placement is typically on a wall or ceiling location that provides clear acoustic paths to all protected glazing within the 6-metre range. The detector should be installed in relatively quiet environments where glass break sounds will be clearly distinguishable from normal background noise. Avoid positioning near sources of loud or sudden sounds such as speakers, telephones, or mechanical equipment that might generate false alarms.

What types of glass can the DET-2R-GB detect and are there any limitations?

The DET-2R-GB uses pattern recognition technology designed to detect the breaking of standard glazing types including plate glass, tempered glass, and laminated glass commonly found in residential and commercial windows and doors. The detector analyzes both the initial impact sound and the characteristic high-frequency acoustic signature produced when glass fractures. However, the detector is optimized for quiet environments and may not perform reliably in locations with high ambient noise levels, constant background sounds, or frequent loud noises that could mask glass break signatures or trigger false alarms. Very thick or specialized glazing types such as bullet-resistant glass, certain types of safety glass, or glass with acoustic damping properties may produce different acoustic signatures that could affect detection reliability.

How long does the battery last and how will I know when it needs replacing?

The DET-2R-GB operates on a single 3V CR123 lithium battery, providing approximately 24 months of typical service life under normal operating conditions. Battery longevity depends on factors including detection frequency, ambient temperature, and wireless communication activity. The detector’s Scantronic Secure Radio (SSR) technology continuously monitors battery status and wirelessly reports low battery conditions to the control panel, providing advance warning before battery depletion affects device operation. The control panel will generate a low battery indication allowing timely battery replacement during routine service visits. The wireless supervision feature ensures battery status is regularly communicated, preventing unexpected detector failure due to battery exhaustion.

Can the DET-2R-GB be used with non-Scantronic control panels?

No, the DET-2R-GB is designed specifically for use with Scantronic control panels that support either Scantronic Secure Radio (SSR) wireless technology or legacy 868MHz Scantronic wireless systems. The detector’s dual-mode capability (SSR at 868-868.5MHz or Legacy at 868.6625MHz) enables compatibility across different generations of Scantronic panels, but the proprietary wireless protocol and encryption are not compatible with third-party control panels. The advanced SSR features including AES128 encryption, bidirectional communication, over-the-air updates, and rapid event notification require compatible Scantronic panel electronics and firmware. Installers must verify that the control panel supports wireless glass break detectors and is configured for the appropriate operating mode (SSR or Legacy) during system enrollment.

Does the glass break detector require any special programming or walk testing?

Yes, the DET-2R-GB must be enrolled with the Scantronic control panel during installation following the procedures in the panel’s installation manual. After enrollment, thorough walk testing is essential to verify proper detection performance. Testing should include simulated glass break sounds at various locations within the protected area to ensure the detector reliably responds to glass break signatures at the expected 6-metre range. Many installers use commercial glass break simulators or test applications that generate standardized glass break acoustic signatures for consistent testing. The detector should not activate in response to normal environmental sounds, loud voices, door slams, or other benign acoustic events. Testing in the actual installation environment ensures the detector’s sensitivity is appropriate for the acoustic characteristics of the protected space.

What is the difference between SSR mode and Legacy mode operation?

SSR (Scantronic Secure Radio) mode represents the advanced wireless technology featuring AES128 encryption, true bidirectional communication, over-the-air firmware updates, and optimized battery efficiency through shortened response times. Legacy mode provides compatibility with older Scantronic 868MHz wireless systems that predate SSR technology, operating at 868.6625MHz with traditional wireless communication protocols. SSR mode offers enhanced cybersecurity through proper encryption (not just encoding), future-proofing through remote firmware updates, and improved system responsiveness. The detector automatically operates in the mode appropriate for the control panel it’s enrolled with. New installations with SSR-capable control panels should use SSR mode to benefit from the advanced features, while Legacy mode enables the detector to integrate with existing older Scantronic wireless systems during upgrades or expansion of established installations.
