Jemay Photoelectric Smoke Detector with 9V Battery (2-Pack)
Hardwired with battery backup and whole-home interconnection for reliable, early fire detection.
Jemay’s smoke detectors use a photoelectric sensor. This matters because it’s better at detecting the slow, smoldering fires common in modern homes filled with synthetic materials. The sensor reacts to visible smoke particles, aiming to give you more time to react before flames erupt.
The alarm is loud, rated at 85 decibels. That’s enough to wake you from a deep sleep. A single test-silence button lets you check the alarm or hush a false alarm from cooking smoke. The minimalist design is a simple white disc that blends into your ceiling. You install them with two screws and a 9V battery powers each unit.
These are straightforward, battery-operated units. They are not interconnected, so if one alarm sounds in the basement, it won’t trigger the unit in your bedroom. For a basic, reliable photoelectric alarm that’s easy to install, this two-pack covers the key areas of a small home.
