Product Description
Ultrasonic presence detection for a working room
STEINEL US 360 COM1 UP, article 007935, is a ceiling-mounted ultrasonic presence detector for offices, meeting rooms and classrooms. It automatically switches a separate lighting circuit by evaluating movement and the ambient-light level. Its 40 kHz ultrasonic sensing spreads around objects in the room, making it useful around desks with screening. Detection does not rely on changes in the heat radiated by an occupant. Room layout still influences coverage, so sensitivity should be set with the actual furniture and intended working positions in place.
Distinguish presence coverage from larger movements
The 360° presence and tangential detection zone reaches Ø6 m, approximately 28 m². For substantial movement in a radial direction, the manufacturer specifies up to Ø10 m, or 79 m². These are diameter measurements. Plan desk coverage using the smaller presence zone. The current diagram shows these zones at a 2.8 m mounting height; the permitted installation range is 2.5–3.5 m. Electronic sensitivity adjustment can reduce coverage to suit the room. Once the settings are chosen, check response at desks, entrances and partitions, taking account of moving fans and open doorways.
Choose how the room should respond
The COM1 version provides one lighting switching output. In fully automatic mode, it turns the lighting on and off according to presence and the selected light threshold. In semi-automatic mode, an external pushbutton switches the lights on and the sensor switches them off automatically. This choice suits both regularly used routes and rooms where occupants prefer to decide when artificial lighting is required. The external control can be configured for ON-only operation or for manual ON and OFF commands.
The stay-on time adjusts from 30 seconds to 30 minutes, and the light threshold from 10 to 1000 lx, with daylight operation and a TEACH function also available. IQ mode learns the usage pattern and adjusts the delay within a 5–20 minute range. Pulse mode can control a compatible stairwell lighting timer: an approximately 2-second output pulse is followed by an approximately 8-second pause, with daylight operation used in this mode. Potentiometers and DIP switches provide settings at the device. Compatible RC8 and Smart Remote controls are available separately.
Select the lighting load and connection arrangement
The relay supports a maximum resistive load of 2000 W at cos φ = 1. For LEDs, the permitted total depends on individual lamp wattage: 100 W total for lamps <2 W, 300 W total for lamps >2 W and <8 W, and 600 W total for lamps >8 W. The specified total capacitive load is 176 µF. Ballast selection must also take account of the manufacturer's maximum inrush-current figure of 800 A for 200 µs. For specified fluorescent configurations, the manual also limits electronic ballast counts to 30 × (1 × 18 W), 25 × (2 × 18 W), 25 × (1 × 36 W), 15 × (2 × 36 W), 20 × (1 × 58 W) and 10 × (2 × 58 W). Check the individual ballast inrush current when selecting the load. Total wattage alone does not establish compatibility for a group of luminaires. The sensor provides a switched-live L′ output and needs both L and N for its supply.
Wired Master/Master or Master/Slave interconnection supports up to 10 sensors on the same phase. In a Master/Master arrangement, each master controls its own lighting group using the brightness it measures. In a Master/Slave arrangement, the additional sensors report detected movement to the master. This helps cover layouts that need more than one detection position. The offered COM1 version provides lighting ON/OFF control. It does not provide brightness dimming or a separate ventilation output.
UP installation and housing
This is the white RAL 9010 COM1 UP version for concealed wiring at an indoor ceiling. In-ceiling and surface-mounting adapters are available separately. Allow for a 120 × 120 mm body with 68 mm total depth, as shown in the dimension drawing and manual; the current manufacturer data table lists a depth of 67 mm. Net weight is 203 g. The plastic housing is rated IP20, with electrical protection class II, a −25 to +55 °C operating range and a five-year manufacturer's warranty. The ultrasonic detector remains IP20 with a suitable surface-mounting adapter.
The first gallery image shows US 360 COM1 UP 007935. The additional photograph against a dark background illustrates the US 360 family housing in the manufacturer's planning material for the DIM version. The offered sensor is the COM1 ON/OFF version; the DIM version's brightness-control functions do not apply. The technical illustrations show detection and wiring for the COM1 model described here. Room equipment and separately available accessories are not included with the sensor.
