Hager has launched its new bus-based building services control system, Tebis TX. The system uses a single twisted pair cable and/or RF technology to link input and output devices. It’s KNX compatible, so can be used with other manufacturers’ products. A simple hand-held remote control programmes the devices.

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

Tebis TX enables inputs such as wall switches, timers, PIR sensors, photoelectric cells and thermostats to communicate and switch output devices. These could include lighting, heating, burglar alarms and motorised curtains. Any single input device or combination of input devices can switch or control any combination of output devices.

For commissioning, contractors can use the hand-held remote control to assign addresses to the input and output devices. They can then decide which output devices should respond to which input devices. When this is completed, installers can save the programme onto a smart media card, which makes it simple to change or upgrade the control scenarios in future.

For commercial applications that share the same building layout, such as retail outlets or leisure centres, the smart card saves commissioning time on future projects.
