The EK-WL8-OV is a wireless optical smoke sensor that incorporates a voice sounder and visual alarm device (VAD) with white LEDs and 0.5 Hz flash rate. The sensor utilises optical smoke detection technologies and algorithms for improved performance, which can contribute to reducing unwanted alarms. Utilising well-proven adaptive radio signal processing algorithms ensure the highest levels of life safety and system reliability are achieved.
