Ecoey Smoke Detector with Advanced Photoelectric Technology, Fire Alarm for Bedroom and Home, 8 Packs

ADVANCED PHOTOELECTRIC SENSORS: Equipped with photoelectric sensors, smoke detectors have an average response time of 15-50 minutes faster than ionisation sensors, helping to prevent fires in their early stages. An audible alarm of ＞85dB at 3 metres further enhances the device's effectiveness.

MINI BUT MIGHTY: The compact smoke detector, small enough to be held in one hand, is easier to install and disassemble, providing long-lasting protection for you and your family with its 10-year lasting chip.

BATTERY EQUIPPED AND REPLACEABLE: The battery-operated smoke detector FJ138 comes pre-equipped, eliminating the need to purchase additional batteries. When the battery runs out, simply replace it with a new one to restore the smoke alarm's functionality.

LOW BATTERY WARNING: The smoke alarm's red LED light and chirp will alert you every 32 seconds when the battery is depleted, allowing you to replace it with a brand new one in a timely manner. Refer to the instruction manual for compatible battery models and installation instructions.

CHOOSE YOUR PREFERRED INSTALLATION METHOD: The fire alarm smoke detector FJ138 is designed with both screw packs and magnet sheets, enabling you to install it according to your preferred method, without the need for hard wiring.

TEST/SILENCE FUNCTION: After confirming that there is no fire hazard, press the silence button for 5 seconds to stop any false alarms. For regular use, test the smoke alarms weekly to ensure their proper functioning.
