Czujnik obecności Z-Wave MCO – montowany na ścianie (OS12)

True Presence Detection on the Wall

The MCO Home OS12 is a wall-mounted Z-Wave occupancy sensor that knows when a room is occupied, not just when someone walks through it. Using 24 GHz millimetre-wave radar, it picks up large movements, small movements and even the breathing of someone sitting still, so lights and heating no longer switch off while you read, work at a desk or watch TV.

More Reliable than a Motion Sensor

Conventional PIR motion sensors only see movement and are easily fooled by heat, sunlight and draughts. Radar detection is not affected by temperature, humidity, noise, airflow, dust or light, so the OS12 gives far fewer false triggers and far fewer lights turning off on people. It switches between occupied and vacant in under half a second for a fast, natural response.

Wide Detection Coverage

The sensor covers a beam of up to 80° horizontally and 85° vertically. It detects walking and larger movements across a 5–8 m diameter area, minor movements such as typing or turning a page across 3–4 m, and breathing within 2–3 m. That makes it well suited to living rooms, offices, meeting rooms, bathrooms, hotel rooms and holiday lets.

Built-In 5 A Relay Output

As well as reporting occupancy to your Z-Wave controller, the OS12 has a built-in 5 A dry contact relay output. It can switch a light, fan or other appliance directly when the room is occupied, without relying on the controller or any other device. Use it on its own for simple occupancy switching, or combine it with scenes and automations for whole-home control.

Mains Powered, No Batteries

The OS12 runs from a 90–250 V AC mains supply, so there are no batteries to replace and it is always ready to report. A visual LED shows pairing status and can indicate when movement, minor motion or breathing is detected, which helps when positioning and testing the sensor. The housing is V0 flame-retardant PC, and it is rated for indoor use from -10°C to 50°C.

Z-Wave 800 with S2 Security

Built on the Z-Wave 800 series with S2 encryption, the OS12 works with any certified Z-Wave controller, including Home Assistant, Hubitat and Homey Pro, and with other certified Z-Wave devices. Its radio output is ultra-low power. It is the wall-mounted partner to the ceiling-mounted MCO OS11, so you can choose the best position for each room. Installation should be carried out by a qualified electrician.
