When smoke is detected, the alarm activates with a current of less than 45mA, accompanied by a red indicator light. The alarm emits a loud sound of over 85dB at a distance of 3 meters, ensuring timely notification in case of fire hazards. With a sensitivity range of 0.08-0.16 dB/m, it is designed to detect smoke accurately. The SD-422L is designed for environments with temperatures ranging from 0℃ to +50℃. Certified by CE and compliant with EN14604:2005/AC:2008, it guarantees safety and performance. The smoke detector has compact dimensions of Ø132 x 41mm, making it easy to install and suitable for various locations.
