What it is
Summary
AI-generated from vendor-published content · April 26, 2026
This hard-wired smoke and carbon monoxide alarm includes two programmable relay outputs, which allow it to trigger external devices — such as bed shakers, strobe lights, or other alerting equipment — when smoke or CO is detected. It's designed for people who are deaf or hard of hearing and need fire and CO alerts delivered through visual or tactile signals rather than (or in addition to) the built-in 85 dB horn. This is not a complete alerting system on its own — the relay outputs connect to separately purchased strobes, pillow/bed shakers, or a whole-home alerting network, and professional installation is required for the hardwired electrical connection. Relay programming and compatibility with specific alerting devices should be confirmed before purchase, and the one-year warranty is shorter than many competitors in this category.

What Setup Looks Like
- Out of the box
The built-in horn and alarm indicator function as soon as power is connected — no additional setup required for basic smoke/CO detection. - With a guide
- Identify which external alerting devices (strobes, bed shakers) you plan to connect to the relay outputs.
- Review relay programming options in the installation manual to configure normally-open or normally-closed operation for your alerting equipment.
- See manufacturer support resources for detailed instructions.
- With professional help
- A licensed electrician must hardwire the unit to AC power and integrate it into the home's alarm circuit.
- An AT specialist or certified low vision/hearing professional can help select and wire compatible visual/tactile alerting devices to the relay outputs.
- Expect 1–3 hours for installation depending on home wiring and number of interconnected devices.
