Honeywell Home 5853 Wireless Glassbreak Detector offers uncompromised performance and unmatched false alarm immunity. The FlexCoreTM signal processor utilizes an Application Specific Integrated Circuit (ASIC) - processing sound data in parallel rather than sequentially. This permits sound frequency, duration and amplitude to be analyzed 50% faster to minimize false alarms while maintaining the highest possible level of detection.The 5853 can be mounted on any wall or ceiling within a 25’ range, with no minimum range limitation. The LEDs indicate test mode, alarms and trouble conditions. It is compatible with all 5800 series wireless devices.
