Emergency lighting – Looking back at DALI emergency lights in Westfield Shopping Center

Westfield Shopping CentreThe Westfield Shopping Centre in London is one of the largest shopping centres in Europe with 280 retail outlets and 50 eateries. At the time of construction in 2011 the focus was on innovation and sustainability. Fast forward three years to review our involvement in the success of the building.

In 2011 Safelincs won the contract to supply Westfield with high quality DALI addressable emergency lighting connected to a DALI digital lighting control system. DALI systems reduce the inspection and maintenance requirement for lighting, especially emergency lighting.

The use of natural light and efficient lighting amongst other energy saving measures ensured that Westfield achieved an ‘excellent’ BREEAM (environmental rating).

All Safelincs emergency lighting units were manufactured with integrated control and diagnostic capabilities adhering to strict efficiency specifications without compromising performance.
We upgraded our MP8 and ES8 emergency lights to DALI technology which were then used on all emergency exit routes, final exits and communal spaces in the shopping centre. DALI systems perform the necessary self-diagnostic tests in accordance with BS5266. Each emergency light sends its self test results to the central panel and if a malfunction is found with an individual lighting unit, the specific fault is highlighted.
MP8 were supplied in a chrome finish, complimenting the shopping centre’s interior design.Our maintained (always on) version of ESW units were placed outside of all final exits. Protected up to IP65, the ESW is a tough waterproof unit ideal for external installation.

The use of DALI addressable emergency units into the lighting control system made a very complex system easy to manage. The emergency lighting supplied by Safelincs has delivered long term value for our customer – in terms of operational savings, fire safety and energy savings. We look forward to being involved in future projects such as this.

Addressable Emergency Lighting

Utilising DALI technology, Safelincs can offer fully Addressable Emergency Lighting Solutions with a full range of emergency light that can also be incorporated in existing DALI networks and building management systems.
What is DALI?
DALI stands for Digital Addressable Lighting Interface and is a protocol set out in the technical standard IEC 62386. DALI is an international standard set out to guarantee the compatibility of products from different manufacturers.
DALI Addressable Emergency Lighting
After the initial installation of emergency lighting, there is a legal requirement for the building occupiers, owners and nominated responsible person(s) to ensure that the emergency lighting system within a building is tested and maintained in accordance with BS5266 – Code of practice for emergency lighting of premises. The associated maintenance and testing labour costs have resulted in the development of fully addressable emergency lighting solutions. These addressable systems perform the necessary scheduled tests in accordance with BS5266, each luminaire then reports back to the central panel or computer with the test results. If there are any malfunctions found with an individual luminaire the specific fault is highlighted at the centralised monitoring point, with the unique address of the luminaire at fault.

These systems have an increased initial cost, but can be easily justified with short payback periods due to reduced costs for testing the systems. The DALI addressable emergency lighting systems enable a lighting designer or planner to assemble a fully addressable system with the advantage of the DALI protocol enabling a mixture of manufacturer’s emergency luminaires on each addressable system.

APPLICATIONS:
Schools, Hospitals, Hotels, Local Authority buildings and any medium to large installations

Safelincs’ manufacturer Ringtail offers a complete addressable system incorporating the monitoring panel, the software and all luminaires. All of these can be incorporated into an existing DALI network. Each DALI system offers the following functionality:

Centralised fully automatic testing and monitoring incorporating

  • Full rated test at commissioning
  • Monthly function test
  • Annual duration test
  • Fully addressable
  • Flexibility for testing schedules, grouping
  • Diagnostic information for rectification of faults and scheduled maintenance
  • Easy commissioning features
  • Communication to proven DALI protocol

Ringtail DALI Luminaires can be linked to any DALI system, however, our complete addressable emergency lighting system incorporates a discrete touchscreen facility with the potential of up to 120 luminaires being controlled and monitored by each touchscreen. Each touchscreen is pre-loaded with its own software and provides a fully DALI emergency compliant system, a number of options are available allowing each touchscreen to operate as a stand alone system or alternatively, on larger installations, these touchscreen panels can be networked together via the building’s ethernet and back to a central monitoring PC. Up to 10 DALI panels can be networked, enabling a maximum of 1200 emergency luminaires to be monitored.

The system is unique in that until the luminaires have been commissioned onto the DALI network they revert to standard Self-test, this means that even before the DALI system has been commissioned that the site will have a fully compliant emergency lighting scheme complete with Self-test.
The DALI function is available on most of Safelincs’ emergency lights; please refer to each individual datasheet for full specifications. We are also able to offer a full range of DALI emergency conversions to existing and other manufacturer’s luminaires.
