Resideo Smoke Detectors
Two battery operated Resideo alarms: a smart smoke and carbon monoxide alarm powered by a 3V CR123A lithium battery, and an 85 dB ionization smoke alarm that runs on a 9V battery. Test alarms monthly, follow Resideo's placement instructions, and replace them by the date on the unit.
