Set of 4 battery-operated (9V) smoke detectors with photoelectric technology, UL listed, with LED indicator and test button for use in private homes and hotels

Precise and sensitive: Our battery-operated 9V smoke detector uses advanced photoelectric technology to detect smoke quickly and accurately. Once a certain smoke level is reached, the smoke detector triggers a loud alarm. This allows you to detect a fire before it can fully spread.

9V battery-operated smoke detector: The smoke detector is powered by a replaceable battery that lasts for one year. Even a power outage will not affect its function. However, remember to replace the battery in a timely manner.

When the indicator light is illuminated, a beep sounds. This signals a low battery level and that the battery needs to be replaced immediately. Easy installation: The smoke detector can be installed in minutes without rewiring. Mounting is simple using the included screws, wall plugs, and brackets, or with a magnetic adhesive pad (not included) on the wall or ceiling. We recommend installing a smoke detector in every room (except the bathroom and kitchen). LED indicator and mute button: Smoke detectors have a mute button. When testing the smoke detector, first press the test button. The LED will then flash red and the alarm will emit a loud beep. To ensure your safety, we recommend having your smoke detector tested monthly.
