Review Summary

This is the summary of consumer reviews for First Alert 2-in-1 Z-Wave Wireless Smoke Detector & Carbon Monoxide Alarm, Battery Operated. The BoolPool rating for this product is Very Good, with 4.10 stars, and the price range is $44.97-$47.09.

The First Alert 2-in-1 Z-Wave Wireless Smoke Detector & Carbon Monoxide Alarm is a reliable product to keep a family safe. Through its use of photoelectric smoke detection and electrochemical carbon monoxide detection technologies, rest assured day and night that your home is being protected from any kind of danger. This product uniquely connects to any smart home technologies and hubs for integrated safety, and is easily installed to alert the homeowner via text, email, or alert when there is an emergency with smoke or carbon monoxide while away from the home.

The alert system includes top of the line safety features like a tamper-resistant battery drawer and a test button for frequent battery checks as needed. The compact device is barely noticeable on the ceiling but is so critical in the safety of a family and a home. Customers say this product has repeatedly alerted them with a loud sound to smoke or chemicals infiltrating the home, giving them plenty of notice to get themselves and their loved ones to safety. Customers also say pairing the device with an existing home integration system is simple and fast.

Some have had issues with battery life in the smoke detector, although it is unclear if this relates directly to the product, or is in fact a problem with the batteries themselves. Some users have said that just after a few months of having the product, lithium batteries died and needed to be replaced earlier than usual for this kind of product. Others say they had issues with the test beep going off without being triggered.

This product is a staple for any home as a first alert system to some of the most common dangers homeowners face. First Alert comes highly recommended with this trustworthy product.

These have only been installed for eight months, batteries should last a LOT longer than that for a smoke detector.

Installation of these detectors is pretty much the same as more traditional smoke detectors, but you get the added safety of having them integrated into your home automation system, linked to security lights, and Pro Weiding real-time updates to your smart phone to keep you apprised of issues with smoke or carbon monoxide.
