DALI Testing System

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. Ventilux offers a wide range of products compatible with DALI Testing System.


DALI is a smart testing system requiring ZERO physical maintenance. It 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. It saves mid term maintenance cost with its automated testing over conventional testing. 

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.  Considerable cost saving against the ever-growing maintenance costs.

DiiA estimated that DALI is currently used in over 54% of SMART buildings in UK & Ireland and 32% globally, which will increase DALI2 implementations.
