Product information

Description

The Steinel True Presence® COM1 UP ceiling-mounted presence detector (model ST057923) is designed for accurate detection of human presence in indoor spaces. Installed flush in ceilings, it uses True Presence® sensing to detect micro-movements and breathing, enabling reliable differentiation between actual human presence and other motion sources. The unit is intended for control of lighting and HVAC systems where precise occupancy information improves comfort and energy efficiency.

Advantages

The device provides high sensitivity to very small movements and stationary occupancy through advanced sensing algorithms, reducing false triggers from non-human motion. Its ceiling-mounted design offers unobtrusive installation with a wide detection area and consistent coverage. Integration capability with lighting and ventilation systems supports automated control and energy savings without manual intervention.

Suitable for

  • Office spaces and open-plan work areas
  • Corridors and stairwells
  • Meeting and conference rooms
  • Residential communal areas and hallways

Key specifications

  • Mounting type: recessed ceiling installation
  • Detection technology: True Presence® micro-movement and breathing detection
  • Detection coverage: wide-area ceiling coverage suitable for typical room heights
  • Output: interfaces for lighting and HVAC control (integration-ready)
  • Operation: automatic presence detection for occupied/unoccupied switching
  • Installation: designed for fixed ceiling mounting with discreet appearance

How to use

Install the detector flush into a suitable ceiling opening at the recommended central position for optimal coverage. Connect the device to the building’s lighting and HVAC control circuits according to the installation guidelines and wiring standards. Configure sensitivity and time delay settings as required for the specific space to ensure reliable detection of stationary occupants while avoiding unwanted switching. After commissioning, verify coverage by walking and remaining stationary in typical positions to confirm detection and correct integration with the control systems.

Usage recommendations

Position the sensor centrally in the monitored room and avoid mounting near large heat sources or direct air vents that can affect detection. Adjust sensitivity and time delay to match the activity level of the space—for example, higher sensitivity and longer hold times in meeting rooms to detect stationary occupants. Regularly inspect mounting and wiring during maintenance checks to ensure continued reliable operation.
