The Vivanco smoke detector set consists of four high-quality smoke detectors designed for indoor use. These devices provide reliable safety through acoustic warning signals with a volume of 85 dB, which demand immediate attention in the event of a fire. Each smoke detector is equipped with an acoustic function test and a visual function indicator, allowing for easy verification of operational readiness. The test button enables regular testing of the devices to ensure they function properly in an emergency. The smoke detectors are powered by a 9-volt battery included in the package, and they emit a warning message when the battery is low, further enhancing maintenance and safety.
