Frequently Asked Questions - VMBPIRO-W-20 Velbus

How do I install the VMBPIRO-W-20?

Mount the sensor on a wall or ceiling using the provided screws. Connect the Velbus bus wires (24V DC, data +, data -) following the polarity. Ensure the sensor is not obstructed by furniture or curtains.

What is the detection range of the VMBPIRO-W-20?

The PIR sensor can detect motion up to 12 meters under ideal conditions, depending on mounting height and environment. The detection angle is 110°.

Can I adjust the sensitivity of the motion sensor?

Yes, sensitivity can be configured via the Velbus software (e.g., VBus). You can set the threshold for motion detection and adjust the twilight sensor level.

Does the sensor include a light sensor?

Yes, the VMBPIRO-W-20 has a built-in twilight sensor that measures ambient light. This allows you to trigger actions only when it's dark, for example, for automatic lighting.

What is the power supply requirement?

The sensor is powered by the Velbus bus voltage of 24 V DC. It does not require a separate power supply.

Can I use the VMBPIRO-W-20 outdoors?

No, this device is designed for indoor use only (IP20). For outdoor applications, consider a weatherproof Velbus sensor.

How do I connect the VMBPIRO-W-20 to my Velbus system?

Connect the three wires: red (24V+), black (GND), green (data+), white (data-). Use a twisted pair for data lines. Ensure the bus is terminated properly.

What is the typical use case for this sensor?

It is commonly used for automatic lighting control, security alarm triggers, and occupancy-based HVAC adjustments in home automation systems.

How do I reset the sensor to factory defaults?

You can reset the sensor via the Velbus software by selecting the device and choosing the 'factory reset' option. Alternatively, power-cycle the device while holding the reset button (if available).

Where can I find the user manual for the VMBPIRO-W-20?

The manual is available for free download on notice-facile.com. Search for VMBPIRO-W-20 and download the PDF. You can also request a translated version by email.

Outdoor motion, twilight and temperature sensor - white

The VMBPIRO is much more than an outdoor motion detector. This adapted Theben sensor allows you to simultaneously use motion and light sensitivity as well as temperature measurement. The built-in astronomical clock allows the VMBPIRO to operate time-dependently. The module also simultaneously detects motion for a passage signal or light dependent movement for lighting control.

White ceramic shower unit with a clear glass lid, no visible text or symbols on the device itself.
