Attention high 2! High-frequency corridor sensor Presence Control PRO Dual HF COM1 AP for indoor use, ideal for corridors and long hallways, installation height up to 3.5 m, surface-mounted version for controlling lights. DUAL-HF technology with dual directional characteristics for up to 20 m radial detection, temperature-independent detection. HF sensor technology penetrates glass, wood, and lightweight walls, enabling particularly quick light switching. Live comfortably while saving energy. Enhanced quality of life, safety, and energy savings through intelligent sensor technology from STEINEL. Light on/off – automatically. Highly innovative sensors respond to movements and lighting conditions, switching the light on automatically without delay and turning it off after a set time. High-frequency corridor sensor Presence Control PRO Dual HF COM1 AP in an installation-friendly surface-mounted version. With COM1 interface for controlling lights based on ambient brightness and presence in corridors and hallways. For comfortable ceiling surface mounting! The system operates with two special high-frequency sensors with dual directional characteristics from the ceiling, reliably detecting both directions of the corridor with a radial range of 20 m, independent of temperature. The range can be proportionally adjusted in both directions. Adaptation to specific usage situations is achieved through additional functions via potentiometers and remote control. For example, IQ mode for automatic adjustment of the after-run time to room usage, impulse mode for controlling a stairwell automation, DIP switches (semi/full automatic, push-button/switch operation, etc.). The detection range can be extended through master/master or master/slave networking. Optional remote controls allow for comfortable installation and operation.
