Fire detector FDR-26-S
Fire detector FDR-26-S
Optical-smoke fire detector suitable for connection to Quido I/O modules.
The sensor works on the principle of smoke entering the evaluation space inside the sensor, which is illuminated by infrared light and the change of reflection parameters over time is evaluated. More
