The KNX standard automatic switch is plugged onto a flush-mounted bus coupling unit. It reacts to changes in temperature like people moving into the detection area. This causes switching commands to devices such as binary outputs to switch groups of lights. The automatic switch has a detection angle of 180°. This angle can be restricted to 90° with a slip-on screen.

Two different standard automatic switches are available:

• Device for 1.1 m mounting height (ref-no: ..3180..)
• Device for 2.2 m mounting height (ref-no: ..3280..)

The standard automatic switch has three applications:

• PIR single unit for stand-alone installation
• PIR master unit for master/extension installation (e.g. long corridor)
• PIR extension unit for master/extension installation

In connection with the KNX system, the functionality of this device depends on software. Detailed information on loadable software and attainable functionality as well as the software itself can be obtained from the manufacturer’s product database.
