DALI (Digital Addressable Lighting Interface) is an intelligent addressable emergency lighting testing solution It allows an installation to be supervised, tested, and monitored from a central location. DiiA estimated that DALI is currently used in over 54% of SMART buildings in UK & Ireland and 32% globally, which will increase DALI2 implementations.

DALI negates the necessity for a maintenance engineer to physically/visually check all emergency luminaires on a regular basis as is currently required under EN50172 legislation. It also allows the site to be tested during non-working hours hence less disruption to the work environment. Remote access and monitoring are now easier via the intranet and internet – less disruption to the working environment hence saving the end-user money. Modular design allows both small and large installations to be competitively specified. OPEN PROTOCOL allows other DALI emergency lighting products to be used on the system under EN62386 legislation. Testing and maintenance of installations fully compliant with national standards, ensuring end-user peace of mind. Considerable cost saving against the ever-growing maintenance costs.

Key Benefits of Dali

  • Control Panel provides the end user with increased control and visibility.
  • OPEN PROTOCOL modules- customer flexibility.
  • An Ethernet backbone provides greater flexibility for increased distances in the system design and layout.
  • Increased system capacity with up to 24000 fittings (200 controllers) on one system allows ease of further project expansion.
  • Modular design and standalone DALI Control Panels provides greater system reliability, installation and commissioning.
  • Remote access and monitoring is now easier via mobile phone, tablet or PC – less disruption to working environment.
  • Email reporting to key personnel.
  • Testing can be programmed for non-working hours hence less disruption to work environment.
  • Ethernet bus can run up to 2000 meters using fibre cable.
  • Mid term cost savings on maintenance costs for an installation over conventional testing.
