## Summary description

Paradox DG-457 is an acoustic glass break detector designed to sense the sound of breaking glass and trigger an alarm. The unit monitors window and glass areas using an acoustic sensor tuned to glass fracture frequencies. It is intended for integration with alarm systems to protect residential or commercial windows, display cases and glass doors by providing audible-break detection and alarm input to control panels.

## Long description

Paradox DG-457 is an acoustic glass break detector that senses and reports the characteristic sound of breaking glass. Designed for integration with wired alarm systems, the DG-457 monitors windows, glass doors and display cases by detecting glass fracture frequencies and sending an alarm input to a control panel. The compact sensor houses an acoustic transducer and internal signal processing that distinguishes glass break events from normal ambient noise.
Advantages
The DG-457 provides focused acoustic detection tuned specifically to the sound profile of glass breaking, minimizing false alarms from ordinary environmental noises. Its compact form factor allows for unobtrusive installation near windows or inside display cases. The detector interfaces with standard alarm control panels and operates as part of a wired security zone, providing reliable alarm input where glass protection is required.
Suitable for
Residential windows and patio doors
Retail display cases and shopfront windows
Office interior glass partitions and doors
Protected showcases in museums or galleries
Key specifications
Detection method: acoustic sensing tuned to glass fracture frequencies
Coverage: designed for single-window or single-glass-area monitoring (coverage depends on installation location and glass type)
Output: alarm input compatible with wired security control panels
Power: powered from the alarm system wiring (consult control panel for supply specifics)
Mounting: surface mount near the protected glass area
Operating environment: indoor use; avoid direct exposure to water and extreme weather
How to use
Mount the DG-457 on a stable surface near the centerline of the window or glass area to be protected, following the manufacturer’s recommended distance and angle for optimal acoustic coupling. Connect the detector wiring to the alarm panel’s designated input and power terminals according to system installation guidelines. Configure the control panel to recognize the detector’s zone and set appropriate alarm response parameters. After installation, test the detector using approved test methods to verify detection and correct alarm signaling.
Usage recommendations
Position the acoustic sensor so that its acoustic pathway faces the glass unobstructed and keep it away from sources of repetitive mechanical noise or strong airflows. Use proper calibration and system-level testing after installation to confirm sensitivity and to reduce false alarms. For environments with high background noise or unusual glass types, consult installation documentation or a security professional to adjust placement and settings.
