LSHOME 4 Pack Smoke Detector 9V Photoelectric
Product description
LSHOME photoelectric smoke alarms bring early warning for slow smoldering fires, combining simple installation with audible and visual alerts to help keep households safer. These battery operated detectors come as a four pack with 9V batteries included, making them ready to mount in minutes and useful for bedrooms, hallways, basements and living areas.
Key features
Each unit uses photoelectric technology optimized to sense light smoke from smoldering fires before flames appear. The alarm emits a loud signal above 85 dB at 3 meters and a rapidly flashing red LED when smoke is detected. A center test button checks operation, and the built in safety clip prevents mounting without a battery. According to the manufacturer, the detectors chirp every 32 seconds when batteries are low, so you know when to replace them.

Keep in mind that photoelectric sensors are tuned for smoldering fires, so pairing them with other safety measures helps cover different fire types.
