Steinel IS345 DALI-2 IPD UP round motion sensor

Steinel IS 345 DALI-2 Input Device 057305 is a round, concealed-wiring infrared motion detector from the IS 345 series. It is intended for indoor areas, particularly passageways, corridors and long circulation routes where a narrow, long detection pattern is useful. The white plastic housing is 12.4 cm in diameter and 7.8 cm high, and the detector is installed in the ceiling.

Detection for corridors

The detector has 360° coverage with a 45° angle of aperture. Its tangential reach is up to 23 × 6 m, while radial reach is up to 12 × 6 m. Steinel specifies a mounting height from 2.5 to 5 m, with 2.8 m as the optimum. IP20 defines this model for indoor use. Individual detection segments can be masked, allowing the sensing area to be adapted to the actual route through the space.

DALI-2 data connection

The DALI-2 IPD version communicates collected sensor data to a higher-level lighting-management system via the DALI bus. It is addressable, supports master/slave interconnection and is designed for up to three DALI users. Power comes from the DALI bus at 12–22.5 V, 50–60 Hz. This item is a sensor rather than a luminaire and does not include a light source. The package contains one unit and carries a five-year manufacturer’s warranty.
