This alarm is 120-Volt AC inter-connectable (with maximum 18 compatible devices), which lets the alarm be interconnected with up to 12 other compatible smoke alarms and six compatible devices like bells, horns, repeaters, and door closers to network a comprehensive system for your home. If one unit triggers an alarm, all smoke alarms in the series will sound. The alarm comes with a lithium battery backup to make sure the alarm is working at all times. The dust-reducing packaging helps avoid accidental alarms due to contaminants and the 85dB horn can be inspected with a test button.
