Presence detector Steinel PCPROIRQUATTROHD 4800 — passive infrared sensor, 4800 switching zones, dimensions 120×120×76 mm

Steinel PCPROIRQUATTROHD 4800 is a passive infrared presence detector designed for reliable motion detection in indoor environments. With 4800 switching zones and a compact housing measuring 120×120×76 mm, the device monitors occupancy to control lighting and automation systems. It is intended for integration into offices, corridors, stairwells and other public or commercial spaces where accurate presence detection improves energy efficiency and operational control.

Advantages

The sensor provides high-resolution coverage through 4800 switching zones, enabling precise detection of small and slow movements. Its compact dimensions allow flexible installation on ceilings or walls without significant visual impact. Built for continuous indoor operation, the detector supports automated lighting control to reduce unnecessary energy consumption and to enable hands-free switching. The passive infrared technology ensures low power consumption and simple, reliable motion sensing without emitting signals.

Suitable for

• Office rooms and open-plan workspaces
• Corridors, staircases and passageways
• Meeting rooms and conference areas
• Public buildings, reception areas and lobbies
• Facility management systems and lighting automation

Key specifications

• Detection technology: passive infrared (PIR)
• Number of switching zones: 4800
• Intended mounting: ceiling or wall
• Housing dimensions: 120 × 120 × 76 mm
• Typical use: indoor presence and motion detection for lighting control

How to use

Install the detector on a stable ceiling or wall surface at a location that provides an unobstructed view of the monitored area. Connect the device to the lighting or automation control circuit according to applicable wiring standards and the installation instructions provided by the manufacturer. Adjust sensitivity and detection range where configurable to match room layout and avoid false triggers from heating elements or moving objects. After wiring and commissioning, verify coverage by walking through the monitored area to confirm expected switching behavior.

Usage recommendations

Place the detector centrally in the monitored zone to optimize coverage and avoid installation near large temperature sources, direct sunlight or vibrating surfaces. Regularly check mounting and connections during maintenance cycles and recalibrate sensitivity settings if room layout or usage patterns change.
