What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This kit pairs a hard-wired carbon monoxide detector with a bright strobe light that flashes visually when the CO alarm triggers — making the warning accessible to people who are deaf or hard of hearing and may not reliably hear the audible horn. It's designed for someone who needs a visual alert system in their home or facility, not just an audible one. The CO alarm installs permanently into household wiring with battery backup, and the strobe connects to flash whenever the alarm activates; this is a complete alerting solution for one room, though multi-room coverage would require additional strobe units. Hard-wired installation means you'll need an electrician if you're not comfortable with household wiring, and the strobe is a separate component that must be positioned where it will actually be seen during sleep or rest.
