Tebis speeds fitting of hotel�s lighting controls

A Hager product story

Edited by the Buildingtalk editorial team Feb 16, 2009

Contractor Vastec Systems is using Hager's Tebis bus system to save installation time for a lighting-control system in new ETAP hotels.

Hager is also supplying its panel and TPandN boards for the electrical distribution.

A Belgium-based company called Building and Engineering manufactures a series of modules for each hotel.

These are bolted together to reduce build-time on site.

The sooner the hotel is open the quicker it can earn revenue.

The hotels need both local room plus central lighting-control behind reception.

Using Hager's Tebis bus system, a single twisted pair cable (the bus line) connects all of the wall switches and the lighting circuits.

Each circuit and switch is assigned an address and the system is programmed so that the lighting circuits respond to commands from individual switches.

For the new hotels, the wall switches in a room typically control just one lighting circuit with a central grid-switching panel behind reception providing central control for the whole building.

A hard-wired solution would need multiple cable runs from different distribution boards and multi-core cabling to the grid switch behind reception.

This is time consuming and complicated.

Peter Bryant, project manager for Vastec Systems, said: 'Using a single bus line rather than multiple cables for the lighting control has probably halved the labour time compared with a conventional hard-wired solution.

'The 30V DC bus cabling of the Tebis system can run alongside the other cabling being insulated for 800V.

'We have configured it in a tree arrangement branching off to different switches and panelboards.

For the electrical distribution, each module is pre-wired and Vastec Systems finishes the cabling runs to the distribution boards.

Hager supplies a bespoke panelboard for the mains board and up to four TPandN boards for the electrical distribution - one on each floor.

The most recent hotel at Beaconsfield motorway services had a Hager mains panelboard, which feeds the heating and air-conditioning units, the plant room and the sub distribution boards.

Four 18-way TPandN boards provide the final distribution.
