Gentex SR Smoke Alarm

This unit is designed for versatility and is perfectly suitable for both residential homes and commercial environments like hotels or hospitals. Because it is UL 217 listed, it meets the safety standards required for residential smoke alarm installations.

You are still protected. The unit is hardwired into your building's electrical system but includes a 9V alkaline battery backup that takes over immediately if the main power fails.

These integrated relay contacts allow you to connect the smoke alarm to broader safety or security systems. This means the alarm can trigger other devices, such as a central security panel, remote notification systems, or HVAC shut-offs, when smoke is detected.

Installation is straightforward thanks to the included quick-disconnect wiring harness, which simplifies the electrical connection. The unit also comes with a protective dust cover to keep the sensor clean while you are finishing up the installation.

The alarm features a high-volume 85 dBA horn. This is the industry-standard sound level designed to be loud enough to wake occupants and alert them effectively in an emergency.

Yes, for the device to function reliably, it should be installed in an environment where the temperature stays between 40°F and 100°F. It is not intended for unconditioned spaces like attics or garages that experience extreme temperature fluctuations.
