Gentex S Series SR Hard Wired Smoke Alarm w/ Relay

Summary

AI-generated from vendor-published content · April 26, 2026

This hard-wired photoelectric smoke alarm includes a programmable relay output, which is the key feature that makes it relevant for people with hearing loss — the relay can trigger external alerting devices like bed shakers, strobe lights, or whole-home alerting systems when smoke is detected. It's designed for someone who is deaf or hard of hearing and needs a smoke alarm that can connect to a broader visual or tactile alerting network, rather than relying solely on the 85 dB audible horn they may not hear while sleeping. This is not a complete alerting solution on its own — you'll need to purchase and wire compatible visual/tactile alert devices separately, and installation requires connecting to your home's electrical system. This is a hardwired unit requiring professional electrical installation, and the relay integration with your specific alerting system should be verified for compatibility before purchase.

What Setup Looks Like

• With a guide
  
  1. Verify compatibility between the relay output specifications and your external alerting devices (bed shaker, strobe, etc.).
  2. Connect to 120V household wiring at a standard junction box — refer to included wiring harness and manufacturer installation guide.
  3. Wire relay output terminals to your external alerting device according to manufacturer wiring diagrams.
  4. Test using the push-button self-test function and confirm external alerting devices activate. See manufacturer support resources for detailed instructions.
• With professional help
  
  1. A licensed electrician should handle the 120V hardwired installation to ensure code compliance and safety.
  2. An audiologist or hearing loss specialist can advise on which relay-triggered alerting devices (strobe, bed shaker) are appropriate for your situation.
  3. Budget for one electrician visit (1-2 hours) plus separate consultation if building a whole-home alerting system.
