Review on Wachter 10 Year Battery Photoelectric Detector by Trey Harvey

This is the smoke detector every home needs. It has a 10-year lithium battery that saves you from having to change the battery twice a year. It has a low battery warning (after 10 years) so you know when to replace the entire unit. It's easy to install with the included bracket and hardware. This unit will be in the basement for added warning in the event of a fire. It will flash red every minute to let you know it is in normal working condition.
