Presence sensor Steinel IR Quattro HD-2 com1 — Steinel IR Quattro HD-2 com1 presence detector

Steinel IR Quattro HD-2 com1 is a presence and occupancy sensor designed for indoor lighting and building automation. The device uses quad-element infrared detection to identify both motion and presence, enabling automatic control of lighting, HVAC and other systems. Built for commercial and residential interiors, the sensor supports energy-efficient operation by switching or dimming loads in response to detected activity.

Advantages

The IR Quattro HD-2 com1 provides reliable occupancy detection through multi-element passive infrared sensing, offering improved sensitivity to small movements and longer range coverage compared with single-element detectors. Its configuration options allow integration with standard lighting and automation systems, and the compact design is suitable for ceiling or high-wall installation. The sensor’s detection logic reduces false triggers from transient temperature changes and adapts to typical indoor usage patterns.

Suitable for

• Office rooms and conference spaces for automated lighting control
• Corridors, stairwells and common areas in commercial buildings
• Residential living rooms, hallways and utility rooms
• Integration with building automation or HVAC control systems

Key specifications

• Detection principle: multi-element passive infrared (IR) presence and motion sensing
• Intended mounting: indoor ceiling or high-wall installation
• Coverage: wide-angle detection pattern suitable for rooms and corridors (manufacturer data should be consulted for exact range and angles)
• Output compatibility: switching and dimming control for lighting and automation systems
• Operating environment: indoor temperature ranges and humidity compatible with standard building interiors

How to use

Install the sensor at the recommended height on a ceiling or high wall where the detection zone covers the intended area without obstructions. Connect the sensor to the lighting or automation circuit following applicable electrical codes and the system wiring diagram. Configure sensitivity, time delay and switching thresholds as required by the installation to ensure reliable detection and appropriate lighting behavior. After installation, test the detection zones and adjust orientation or settings to avoid blind spots and minimize unwanted activations.

Usage recommendations

Position the sensor to face the primary activity area and avoid placing it near direct heat sources, air vents or large glazed surfaces that may affect infrared detection. Use the sensor’s sensitivity and time-delay settings to match occupancy patterns in offices or residential spaces for optimal energy savings and comfort.
