Dual HF corridor sensor works with a variant of high-frequency technology. The system is equipped with 2 sensors, each of which controls one side of the corridor. Both together cover a good 20 meters. The tangential range is intentionally limited to the width of the corridor, so that movements behind closed doors, for example, are not detected. DALI broadcast version: no possibility to address the sensor via an external controller. The addressable sensors are in the "DALI2" category.
