Product Description
The USI USI/SM/HW10YR/P/3 is a 3-pack hardwired smoke and fire alarm solution designed for whole-home residential protection, replacement projects, and contractor installations. Each alarm uses photoelectric smoke sensing with Sensing Plus Multi-Criteria Detection, which USI describes as helping identify both slow-burning and fast-flaming fires.
This Pro-Pack is especially useful when replacing multiple hardwired alarms at once. The alarms are interconnectable, so when one compatible alarm sounds, connected units can sound throughout the home. The built-in Voice Alert helps communicate fire alerts and replacement reminders, while the 10-year backup battery helps maintain protection during power outages and reduces routine battery replacement work.
