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.

  • Locking pins deter removal
  • Power indicator lets you see at a glance that the alarm is powered
  • Meets UL standards
  • 10-year limited warranty

CUSTOMER REVIEWS

Rated 4.8 out of 5 by 4 reviewers.
Rated 5 out of 5 by There are not many wired smike detectors out there with Lithium batteries Exactly what I wanted at a good price. I had been looking all over for wired smike detectors with litho=ium battery back ups. These were exactle what I needed, easy to install and no replacing batteries every year. January 14, 2014
Rated 5 out of 5 by SMOKE ALARM / FIRST ALERT EASY TO INSTALL & WORKS REALLY GOOD. FOR A REPLACEMENT UNIT FOR ANY BRAND YOU HAVE OVER 10 YEARS ITS EASY TO DO. GREAT BRAND & GREAT PRICE. 10 YEAR BATTERY IS ALSO GREAT IN THIS UNIT. May 23, 2014
Rated 4 out of 5 by Was looking for 110V and lithium backup Exactly what I was looking for. Replaced 22 year old smoke alarms in a few minutes. November 1, 2013
Rated 5 out of 5 by Up to date protection, easy to install This was a replacement for a 10 year old unit, it was a piece of cake to put in. The bezel that mounts to the ceiling was just slightly larger than the original so it covered the slight indent left by the original. Honestly I think this took about 10 minutes to have fully operational, that included opening the package and glancing at the instructions. March 12, 2014
