## Summary description

Steinel IS345 DALI-2 APC UP is a square motion sensor designed for ceiling installation. The device supports DALI-2 and APC protocols for integration with lighting control systems. It detects presence and movement to control lighting automatically, suitable for offices, corridors, stairwells and commercial spaces where centralized DALI-2 control is used.

## Long description

Steinel IS345 DALI-2 APC UP square for ceiling mount is a compact ceiling-mounted motion sensor engineered for integration with DALI-2 lighting control systems. The device detects presence and movement and communicates with centralized controllers using DALI-2 and APC protocols to enable automatic switching and presence-based lighting control in commercial and public interiors. Its square format is intended for unobtrusive ceiling installation in offices, corridors, stairwells and similar spaces where reliable presence detection and compatibility with modern lighting networks are required.
Advantages
The IS345 DALI-2 APC UP combines motion and presence detection with standardized DALI-2 and APC communication, providing reliable automatic lighting control without the need for additional standalone sensors. Its ceiling-mount design ensures wide coverage and discrete appearance. Compatibility with DALI-2 systems simplifies integration into centralized lighting management and supports energy-efficient operation through presence-dependent switching. The device is designed for professional installations in commercial environments and strives for accurate detection while minimizing false activations.
Suitable for
 Open-plan and cellular office spaces requiring presence-based lighting
 Corridors and circulation areas in commercial buildings
 Stairwells and landings where automatic lighting enhances safety
 Retail and service areas integrated into DALI-2 lighting control
Key specifications
 Sensor type: ceiling-mounted presence and motion detector
 Communication protocols: DALI-2 and APC compatible
 Mounting: recessed/flush or surface ceiling installation (square form factor)
 Detection capability: presence and motion detection for automatic lighting control
 Intended environment: indoor commercial and public interiors
How to use
Install the sensor in the ceiling at the recommended height and position for the planned coverage area, ensuring alignment with the lighting zones on the DALI-2 network. Wire the device according to the project wiring diagram and the receiving DALI-2 controller instructions. Configure presence detection sensitivity, hold times and integration into the DALI-2/APC control software as required for the space. After commissioning, the sensor will switch or dim connected luminaires via the DALI-2 network based on detected movement and presence.
Usage recommendations
Place the sensor centrally within the coverage area and avoid mounting near heat sources, air vents or areas with frequent non-relevant motion to reduce false triggers. Adjust sensitivity and hold time during commissioning to balance responsiveness and energy savings. For optimal integration, use the sensor with compatible DALI-2 controllers and follow local electrical and installation regulations.
