Plug & Play HF On-Off motion sensor complete module. The sensor detects movement via a high-frequency (HF) antenna and is designed for horizontal mounting above the false ceiling, ensuring a concealed solution. The device must be placed near a recessed lighting fixture, using its insertion hole for passage and positioning. It can also be installed near ceiling inspection hatches if the lighting fixture hole does not allow it to pass through. Installation is permitted exclusively for detection from the ceiling downwards. Detection occurs only through materials permeable to radio frequencies, typically used for the construction of false ceilings, such as plasterboard, wood, glass, plastic, and fabric. The sensor is not suitable for false ceilings made of shielding materials, such as solid or perforated sheet metal, metal grilles, aluminium-coated panels, or concrete. It is also not suitable for environments where moving elements or elements subject to vibrations are present even in the absence of people, such as ceiling fan blades, oscillating air conditioning deflectors, or vibration-prone ventilation pipes. The sensor has a power supply input line and an output line for connecting lighting fixtures. - Mains power supply 220-240 V | 50/60 Hz - Power consumption: max <0.45 W - Maximum power on the output line: 200 VA - HF antenna operating frequency: 5.8 GHz, power < 0.2 mW. - Output level with detected movement: 100% (non-modifiable) - Hold time in the absence of people: 5 min (modifiable) - Output level upon expiry of the hold time and in the absence of people: OFF (non-modifiable) - Motion sensitivity adjustable via DIP Switch on 5 levels: 100% - 75% - 50% - 30% - 10% (default 50%) - Hold time adjustable via DIP Switch on 7 levels: 5s - 30s | 1m - 5m - 10m - 20m - 30m (default 5 min) Partition walls made of radio frequency permeable materials, such as plasterboard, wood or similar materials, do not necessarily delimit the sensor's detection area. In such applications, the installer must adjust the sensitivity during commissioning and verify that detection occurs exclusively in the intended room. Under special installation conditions, a preliminary on-site check using a representative mock-up is recommended.
