ONELink Carbon Monoxide & Smoke Detector with Voice
This is a very cool and safe smoke detector and carbon monoxide detector. The ONELink detectors are networked so if one is triggered all of the alarms, up to 16, will all speak and let you know what the danger is. No more waiting for the fire or any other danger to get close to you for the fire alarm to go off. A great way to protect yourself and your family.
