The existing leisure centre, which contained a small 4-lane swimming pool and 55-station fitness room, was simply not big enough for the growing local community.
The lighting-control system was installed by REL Electrical as part of the £900 500 electrical contract.
Steve Jamieson, technical manager with REL, explains, ‘The specification called for a microprocessor-based lighting-control system, and we wanted a simple, single solution that could integrate everything into a single package or, at the very least, minimise the amount of interface wiring that we had to install. The Dupline system gives us a single loop that runs around the building, minimising our cabling and giving us one simple system as a backbone.’
The system is designed to be simple to operate.
When a member of staff arrives in the morning, a simple light switch illuminates just the entrance area. A central back of push switches in the main office will operate lighting in remote areas via the Dupline system.
The swimming pool has two preset lighting levels — 200 and 300 lx. One switch operates lighting fittings to 200 lx, and another brings lighting up to 300 lx.
In changing-room areas microwave presence detectors are linked to 1 to 10 V Dupline controllers to switch on lights when someone enters the space. If no movement is detected for 15 minutes, lights dim down to 10%.
The last member of staff to leave the facility can use a switch to turn off all lighting in the building. If the master switch is not activated by a set time, lighting will be turned off automatically.
Steve Jamieson concludes, ‘This was an electrical-only contract, so we didn’t have the opportunity to integrate the lighting control with the HVAC control, but that is something we would definitely consider in the future.’
