## Long description

The STEINEL Presence Control PRO Dual HF COM1 is a high-frequency wireless motion detector designed for corridor and aisle lighting control. It combines two HF sensors to detect presence and movement from the ceiling in both directions, automatically switching lights on and off according to ambient brightness and presence. The compact unit (120 x 75 x 120 mm) operates at 5800 MHz with a maximum detection reach of up to 20 m (selectable proportionally per direction) and is suitable for installation at heights from 2.5 m. The detector offers adjustable sensitivity, daylight threshold and stay-on times via potentiometers or remote control and supports master/master and master/slave interconnection.
Advantages
The unit provides reliable radial detection in corridors irrespective of temperature and allows directional range adjustment. Its automatic light control reduces energy consumption by switching lights on only when needed and off when areas are vacated. Multiple operating modes (IQ mode, pulse mode, semi-/fully automatic) and remote control options enable flexible adaptation to different usage scenarios. Optional extension via interconnection makes it suitable for larger installations.
Suitable for (tasks / use cases)
Corridor and aisle lighting control in commercial and residential buildings
Staircase lighting with timer (pulse mode)
Areas requiring directional detection from ceiling-mounted sensors
Installations that need master/slave expansion or remote adjustment
Key specifications
Brand: Steinel
Model / MPN: PCPRODUALHF
EAN: 4007841002978
Detection technology: High-frequency (HF), 5800 MHz
Maximum detection reach: up to 20 m radial (proportionally selectable per direction); product listing also notes a 10 m range for typical wireless operation
Light sensitivity (daylight threshold): up to 1000 lx
Installation height: from 2.5 m
Dimensions: 120 x 75 x 120 mm
How to use
Install the detector on the ceiling at the recommended minimum height (from 2.5 m). Configure the detection reach and directional balance using the device potentiometers or remote control as required for the corridor layout. Set the daylight threshold so the sensor only activates the lighting when ambient brightness is below the chosen level. Select the desired operating mode (IQ mode for automatic stay-on time, pulse mode for staircase timer, semi- or fully automatic, button/switch mode) using the DIP switches or remote control. If a larger detection zone is required, interconnect detectors in master/master or master/slave configuration.
Usage recommendations
For reliable performance, mount the detector at the recommended height and avoid installation close to strong heat sources or moving objects that could cause false triggers. Use IQ mode in variable-traffic areas to let the sensor automatically adapt stay-on times, and consider interconnecting multiple units for continuous coverage in long corridors.
