Setup with instructions Most families can set this up with the instructions, since the plug-in connector avoids rewiring. It still means working with household wiring, linking other alarms, and testing the strobe. That is more than a quick unboxing, so it fits guided setup. Anyone unsure about electrical work should have an electrician install it.

What it is

Summary

AI-generated from vendor-published content · October 1, 2026

This hardwired smoke and carbon monoxide alarm warns by sound, by voice, and by flashing light. It comes with an SLED177 strobe, so someone who can't hear a standard siren still gets a visual alert. The voice message says what the danger is and where it is in the home, and an indicator shows which unit set off the alarm. Interconnect lets one alarm trigger all compatible alarms, with up to 12 other First Alert/BRK detectors and 6 other compatible devices. A battery backup keeps it working in a power outage. Because it is hardwired into your home's electrical system, plan on a careful installation, and have an electrician handle it if you're not comfortable with that kind of wiring.

What setup looks like

  • With a guide
    1. Turn off power at the breaker, then use the included Quick Connect plug to connect the alarm to your home's wiring. The plug means you don't need to rewire.
    2. Connect the SLED177 strobe light, install the backup battery, and restore power.
    3. Press the test button to check the siren, voice message, and strobe. If you're linking other alarms, test that they all sound together. Plan on about an hour.
