The new Tebis TX bus-based building services control system from Hager is said to be simple to install and commission. The system uses a single twisted pair cable and/or RF technology to link input and output devices together. It is KNX compatible, so can be used with different manufacturers’ products. The devices can be programmed using a hand held remote control.

Cabling involves no new installation skills. Hager claims that electricians could typically install and commission a Tebis TX system after just half a day’s training – often on site while they are completing a project.

The system enables inputs – including wall switches, timers, PIR sensors, photoelectric cells and thermostats – to communicate and switch output devices, such as lighting, heating, burglar alarms and motorised curtains. Any single or combination of input devices can switch or control any combination of output devices.

For commissioning the contractor uses the hand held remote control to assign addresses to the input and output devices, and then decides which output devices should respond to which input devices. When this is completed, the installer can save the programme onto a smart media card.
