## Description

System Sensor 2WT-B 2-Wire Photoelectric - Thermal With Base

Review: Good quality - Was the exact match I needed for my daycare to pass fire inspection. These are good quality and work excellent
Review: Good replacement for discontinued models - This replaced a discontinued model originally installed in my house. It is the same size, functionality and connection as my old one. It is a hard wired unit but does have a long life non removable battery as backup. It is fairly priced and adheres to the standards of my alarm system.
