Product Description
The USI USI/SM/HWREP/3 is a 3-pack hardwired smoke and fire alarm solution designed for whole-home replacement projects, contractor installs, rental properties, remodels, and residential safety upgrades. Each alarm uses photoelectric 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 the same time. The alarms are interconnectable, helping extend alerts across connected areas of the home, while the replaceable backup battery helps maintain protection during power interruptions. USI’s support documentation also notes that the unit provides end-of-life chirping and nuisance-alarm silence functionality.
