Features automatic self-checking
The Electronics Line Shard SFF-25 is the enhanced, self-checking version of the SF-25. The Shard SFF-25 features an automatic audible circuit test - if no sound is detected for 17 hours the Shard SFF-25 indicates an audio detection failure and automatically notifies the monitoring service of this failure. The Shard SFF-25 glass break detector uses high-frequency audio reception to detect glass breakage within a 25 ft. radius. With the Shard SFF-25, one sensor can cover multiple windows, unlike with traditional on-window sensors.
