Electrical installation specialist Hager has supplied an intelligent and adaptable lighting system for the renovation of a Central London office by combining its klik.system lighting installation and tebis.KNX.
Designed by Concept Design 95, the 7740ft2 open plan office on the fourth floor of Birchin Court has recently undergone a total refurbishment. Using Hager’s klig.system prefabricated wiring system, GT Electrics has been able to save around 50 per cent on lighting installation time when compared to standard wiring systems. And by using ‘plug and play’ prefabricated wiring, the lighting configuration can easily changed to suit the needs of future tenants.
“We chose Hager’s klik.system due to the speed of installation," said GT Electronics MD Guy Tayler. "The system has pre-tested cables, meaning less time on site, while the colour coded plugs allowed our electricians to easily identify which particular circuit the cables run to. Another advantage of the klik.system is the multi-pin plugs, which allow dimming as well as 230V power to each light fitting.”
There are three entrances to the office at Birchin Court. Luminaires are grouped together using klik marshalling boxes and are controlled by a sensor, combining occupancy detection with daylight harvesting. The tebis.KNX bus links the occupancy sensors, switches and KNX actuators to allow control of the lighting circuits.
The alternative hard-wired solution would involve running cables to a switch — this is both labour intensive and inflexible if there are any changes or additions.
Hager’s tebis.KNX system allowed GT Electrics to programme the lighting to create a corridor of light when presence is detected in any of the three entrances, which is especially suitable for the night security guards and late workers. Each sensor can be programmed to be a master and a slave, meaning if a sensor detects presence it will switch on its lights — and it will also communicate with adjacent sensors so that the entire corridor is lit.
Other control includes a time clock, to allow the lighting to turn on and off at pre-set times. At night, the lighting is set to a ten per cent dimmed level for improved energy efficiency.
Says Tayler: “Compared to standard light switches, the Hager tebis.KNX system allows for flexible use of the lighting. The system can be easily programmed and re-programmed in the future, as the office layout is altered.
"Hager engineers came to site both during and after installation to check there were no issues. Using Hager’s klik.system with tebis.KNX has been a good investment, saving us time and the associated costs on installation.”
