Battery-Powered Photoelectric Smoke Detectors, UL Listed, 4-Pack with LED Indicator and Test Button

About this item

• Safe & Reliable: The fire alarm smoke detector not only uses high-quality flame-retardant ABS material and an ultra long lifespan battery, but also blocks external interference in the appearance design to ensure detection accuracy and ensure the normal operation of the photoelectric fire alarm detector.
• Accurate & Sensitive: The photoelectric smoke alarm adopts optimized photoelectric technology, which can more sensitively, quickly, and accurately measure smoke levels. When smoke or fire is detected, the red indicator light of the detector immediately flashes within a range of 3 meters, emitting an alarm sound of 85 decibels.
• Multi-occasion Use: This smoke detector does not contain any radioactive substances. It should be installed in every room (except for bathrooms and kitchens), decorated lofts and basements, schools, warehouses, shops, and other enclosed areas to ensure that everyone can hear the alarm sound and respond.
• Easy Installation: Our smoke detectors are mainly divided into two types: adsorption top type and adhesive top type, both of which are equipped with screws and brackets. The installation operation is simple and can be completed in a few minutes. In addition, the fire alarm smoke detector is not hardwired, so you can install it anywhere you want.
• The fire alarm smoke detector includes a test button for silent activation. Prior to testing the smoke alarm, check the battery status by pressing the test button. If the battery is running low, the detector will emit a low battery alert.
