The optical smoke detector Abus RWM250 triggers an alarm as soon as smoke particles enter the measuring chamber. It covers areas of up to 60 m² when installed at the appropriate height and warns loudly at 88 dB of dangerous smoke development, as well as, thanks to the integrated temperature sensor, when the room temperature rises rapidly. This allows you and your family or housemates to get to safety in case of a fire. Thanks to the magnetic gel adhesive pad technology, the smoke detector can be installed in no time and does not require any drill holes or screws for fixation. The high-quality, permanently installed lithium battery enables a long battery life of the RWM250 of up to twelve years. When the lithium battery is running low, a beep sounds as a warning.
