What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This hardwired smoke and carbon monoxide detector includes a built-in strobe light (the SLED177) that flashes visually when the alarm triggers — making it detectable for people who are deaf or hard of hearing and may not hear a standard audible alarm. It's designed for someone who needs whole-home fire and CO alerting that works even when they're not wearing hearing aids or when ambient noise masks the siren. The unit hardwires into your home's existing electrical system with battery backup for outages, and can interconnect with up to 12 other compatible First Alert detectors so that when one triggers, all units — including all strobes — activate simultaneously. Hardwired installation requires access to your home's wiring, which typically means a licensed electrician if you're not comfortable with electrical work.
