Rely 10-Year Battery, Hardwired (with Battery Backup) Photoelectric Interconnected Combination Smoke and Carbon Monoxide Detector with Voice Alert

Combination sensor/alarm with voice.

Combination Smoke detector and carbon monoxide sensor means I can move my dedicated carbon monoxide sensor to another location in the house. This give even move coverage/safety. My house does not use the daisy chained sensors, so the yellow wire needed to be isolated with a wire nut. I like the voice announcements that tell you if it's a fire or carbon monoxide setting off the alarm.

Easy Installation

I have it in the basement for the carbon monoxide detector. It is easy to install, with clear directions. It comes with a connection plate that is easy to install. The wire harness is also easy to connect to the wires and then simply click into the smoke and carbon monoxide detector.

Great Alarm awesome battery life

Easy installation. Seems like a solid unit. Alarm is very loud and can be heard through closed doors. The idea of never needing to replace the battery or not hearing the “chirp” in the middle of the night helps ease my mind as well.

Love it

An amazing smoke/carbon dioxide detector from Rely this one is a 120v hard wired, with voice alert in English or Spanish, a 10 year warranty, simple installation your basic 3 wire totally exceeds others

Perfect Smoke/C03 Detector

This is the best dual detector I have used. It has both a 120 AC hook up and build-in 10 year battery. It is easy to wire up to 120 AC on a standard box and can be linked to other smoke detectors. The voice command as a nice addition if that appeals to you. The alarm is loud.
