Product Description
Presence detection during quiet activity
STEINEL True Presence COM1 AP is a white surface-mounted ceiling presence detector that uses high-frequency sensing to detect very small human movements. It suits rooms where people sit, read, work at a computer or take part in meetings without making large movements. 7.2 GHz True Presence technology analyses micro-movements, including body movement caused by breathing. Choosing an appropriate detection area and sensitivity scenario helps lighting follow how the room is actually occupied, while retaining a defined relay response after people leave.
Two different detection areas need to be considered when planning the installation. True Presence micro-movement detection reaches up to Ø9 m, approximately 64 m², while movement and conventional presence detection extend to Ø15 m, or 177 m². The manufacturer's reference mounting height is 2.8 m, and the special True Presence function is intended for heights up to 4 m. The broader 2–12 m mounting range therefore does not mean breathing-related micro-movements are detected from a 12 m ceiling. Relating the required detection type to desks, seats and walking routes is a useful first step before selecting the sensor position.
Sensitivity and Bluetooth Mesh configuration
The detection area and sensitivity scenario are configured in the STEINEL Connect app. The manufacturer provides nine scenarios to accommodate quiet office work, more active spaces and environments affected by vibration. A small, quiet office needs a different response from an area containing moving machinery. Scenarios 1 and 2, intended for environments affected by vibration, disable the True Presence function and operate as conventional motion detection. This makes sensitivity a deliberate installation choice rather than an assumption that maximum sensitivity is appropriate everywhere.
Bluetooth Mesh allows the detector to operate individually or alongside compatible products in a lighting group. The app supports grouping, parameter adjustment and neighbouring-group functions, enabling the next lighting area to respond when required. The COM1 version provides one relay output for switching the connected circuit on and off. Fully automatic operation can follow room use, while semi-automatic operation requires a button press to turn the light on and leaves automatic switch-off to the detector. The S input accepts an external button, and compatible network buttons can also be assigned in the app.
The white model includes onboard light-level measurement with an adjustable 2–2000 lx threshold. This allows switching to take available daylight into account, so a presence signal need not turn lighting on in an already bright room. Teach stores the light level measured when the setting is selected. Daylight mode is available when the installation should respond to occupancy regardless of ambient brightness. This model switches a relay; the COM1 output does not adjust the brightness of the connected luminaires.
Timing, connected loads and surface installation
The installation manual specifies a COM1 time range of 30 seconds to 60 minutes. The current product table also lists a 20-second minimum; the available settings for the actual unit can be checked in the app. Selecting an appropriate delay gives a predictable switch-off after the room is vacated. A button preserves manual control, while pulse mode provides a 2-second output followed by an 8-second pause, for example when triggering a compatible staircase timer. The selected function should match what the connected lighting circuit is intended to do.
LED loading depends on individual lamp power: 100 W total for lamps below 2 W, 300 W for lamps above 2 W and below 8 W, or 600 W for lamps above 8 W. The limit of eight LED or fluorescent lamps and the 176 µF capacitance limit apply at the same time. For electronic ballasts, this listing uses the manual’s more conservative 600 W rating. Incandescent and halogen resistive loads are rated at 2000 W; that figure does not apply universally to LED lighting.
The AP housing measures 123 × 123 mm across and 45 mm deep, for surface mounting on an indoor ceiling. The white RAL 9003 finish suits light-coloured ceilings. The surface version has confirmed IP54 protection and operates from 220–240 V AC, 50–60 Hz. High-frequency detection can respond through glass, wood or lightweight partitions, so electronic range adjustment helps keep coverage within the intended area. When choosing a location, the manual calls for at least 3 m separation from a Wi-Fi router or access point. After installation, check performance at the actual positions where people are expected to remain relatively still.
