Applications include residential and institutional applications including hospitals, hotels, motels, dormitories and other multi-family dwellings.

The Spread Spectrum Horn Tone has a lower and varying frequency that makes it easier for those with hearing loss to hear the audible horn. This alarm features two latching features and two silence features. The Alarm Latch easily identifies the initiating alarm even after the alarm condition has subsided. The Low Battery Latch identifies which unit is in low battery condition by blinking the green power light. The Low Battery Silence temporarily silences the low battery chirp for up to eight hours. The Alarm Silence silences the alarm for several minutes. The alarm is interconnectable with up to 18 devices, of which 12 can be smoke alarms.
