The RK100-B detector is a linear optical smoke detector with barrier (separate TX and RX), with a maximum optical range of 120 m (minimum useful distance 25 m). It has 2 independent smoke detection circuits: Clouding and Turbulence - and is capable of detecting white or black smoke, fumes or mists. A single detector can cover an area of up to 1600 sq. m (standards EN54-14 and UNI 9795 ed. 2005) and is the ideal solution for installation in supermarkets, industrial storage facilities, warehouses, theatres/cinemas, shops, hotels, control rooms and, in situations where the optical window for passage of the infrared beam between Transmitter and Receiver is very small (goods storage warehouses with a lot of shelving), an opening of around 10 cm is enough to guarantee the correct beam intensity. Equipped with 2 Alarm relays and 1 fault relay, 0-5 V analogue output for viewing the signal level at a distance and automatic drift compensation circuit. Integrated laser module for quick and precise optical alignment, even at greater distances. Simple installation and easy infrequent maintenance. Power supply 11/30 Vdc. Built-in LED for status indication. IP65 protection rating with polycarbonate housing. VDS and CPR certified in accordance with standard EN54-12.
