Smartwares set of 2 smoke detectors - 5-year replaceable batteries - Fast and reliable detection - 85 dB - FSM-11752

• RELIABLE AND EFFECTIVE: these smoke detectors meet European quality standards to ensure your safety. With their optical sensors, they alert you quickly so you can react as fast as possible.
• 5-YEAR REPLACEABLE BATTERIES: enjoy peace of mind throughout the lifetime of your devices. Each detector is powered by a 9V battery (included) with a 5-year lifespan, which only needs to be replaced once during the device's lifetime. You can rest assured, as an audible indicator will let you know when it needs to be replaced, so you won't forget.
• TEST BUTTON AND SILENT FUNCTION: regularly check that your devices are working properly and press their test button until you hear a short siren. Release the button to stop the sound. If the siren does not sound, your detector is not working properly. You can also put it in silent mode during an alert to reduce the noise while you eliminate the source of smoke.
• 10-YEAR LIFESPAN: Smoke detector sensors have a lifespan of 10 years. After this period, you will need to replace your devices as they will no longer be able to reliably ensure your safety.
• EASY INSTALLATION: Installation hardware (screws and plugs) is included. Choose a strategic location (at least one per floor) and install the detectors on the ceiling according to the instructions in the user manual. Depending on the size of your home, we recommend installing several detectors. These detectors are also available in packs of 4 or individually.
