Easily install and interconnect multiple alarms together to create an alarm system throughout your home. Review: All three of our alarms gave the warning beeps within days of one another. They were finishing warranty also. I was glad to find these with three alarms. Many I had interest in were in two only. Then I’d need two pkgs with an extra one not needed. Others way beyond our senior budget. These arrived on time, safely packed and exactly as described. Our son got them up quickly and easily and we’ve had no trouble with them at all. We recommend them.
