Wireless smoke detector - 916 MHz
Stand-alone wireless smoke detector designed for protection of small areas. SF 900 is an optical smoke detector that uses the Tyndall effect to verify the presence of combustion particles in the air. In particular, reveals cold smoke and visible (with the combustion particles sized between 0,3 μm and 2 μm). It is equipped with a 9-volt battery and emits a modulated sound, compatible with the evacuation signal when it detects smoke. It communicates with the control panel by a bidirectional digital radio transmission channel to avoid signal collisions or band saturation and ensure high stability and precision. The 128 bit AES encryption code guarantee an high security. It is also supervised (automatic life test). The standard lithium-ions battery allows a very long duration.
