The Glassbreak detector TA-456 is designed to distinguish the particular sounds made when perimeter glass is broken, such as plate, laminated and tempered glass, from any other sounds. The complete signal received by the microphone is digitally filtered and analysed by various methods. The digital software uses the data from these methods to complete a thorough analysis of the entire signal to compare to its bank of alarm parameters. Signals originating from common events, such as breaking a glass cup or using a power tool, will not match glass trek's alarm parameters and will be rejected. The detector can also be used to monitor the sounds in the protected area though its audio output.

Features:
1. Frequency distribution
2. Frequency fluctuation assessment
3. Impact and shock wave analysis
4. Digital amplifier gain
5. Signal processing and false alarm elimination
6. Sensitivity settings
7. Alarm LED
8. Audio output
