The LOGIFIRE series 41RFU100 detector is an optical Tyndall-effect smoke detector with a built-in isolator. The digital signal processing algorithms make it particularly sensitive to detecting smoke, even in the early stages of a fire breaking out. Microprocessor-controlled digital signal analysis. Contamination level auto-compensation and maintenance indication. Programmable sensitivity across three levels. Quick cleaning of the sensor chamber thanks to the intuitive disconnection of the components. Evolved design suitable for any type of installation, even in the most aesthetically demanding situations. High-visibility light indications. Automatic addressing or with programmer.
