Hard-wired Smoke Detector - 01/09/2017
Reviewer: Robert Farkas
I needed to replace my detector and was unable to find the same models in the big box stores here or in other home stores in the area. It was so easy to find the exact model on your website. It is installed and is working fine.

The old unit was giving false alarms so it was replaced with this unit and it was an easy replacement. Having a battery backup is a plus!

Reviewer: Frederick Warner
great service and fast shipment. Everything worked perfect.
Other reasons include: It could be a different device or appliance such as a security system, monitor, carbon monoxide alarm, or other device which has a similar low battery or alert signal. Some of the same factors that cause unwanted alarms can cause intermittent alarms: dust and insects in the alarm or power interruptions in hardwired alarms. Improper wiring on AC or AC/DC smoke alarms. AC alarms will chirp every 5 seconds if the interconnect wire is grounded. The orange interconnect wire should NEVER be grounded; it should only be used to interconnect other smoke alarms or compatible devices.
