The Satel ASD-250 wireless smoke detector detects visible smoke using a photoelectric sensor, enabling early detection of signs of fire. It operates independently in accordance with EN 14604 or can be integrated into ABAX 2 and ABAX systems, with audible and visual alarm indicators.

The Swirl chamber and stainless-steel Hexamesh filter support sensor operation, while the chamber contamination check and test mode allow the detector to be checked. In ABAX 2 mode, the ECO* option can extend battery life by up to four times, and the device is protected against tampering by a housing-opening sensor.
