DALI-2 Emergency Lighting Control

Emergency lighting is made up of lighting fixtures that are automatically activated in the event of a power failure, providing an auxiliary light source to ensure the safety of people.
Emergency lighting is mandatory in workplaces, high-risk environments, tourist accommodations, businesses, public entertainment venues, school buildings and kindergartens.
The international standard DALI-2 (Digital Addressable Lighting Interface, second edition) also allows self-powered emergency lamps to be controlled within integrated Lighting Automation systems in all these environments, making it easier for engineers and installers to work in the emergency lighting industry.
Reference Standard for Emergency Lighting
An emergency lighting system ensures the safety of a building and enables the safe evacuation of its occupants or the completion of specific activities that can’t be interrupted, even in case of a power failure. Power can fail at any time, for example due to severe thunderstorms, fire, construction work, or grid overload.
UNI EN 1838 is the European standard for emergency lighting in workplaces, including specific applications such as safety lighting (anti-panic, escape and high-risk areas).
Given the extreme importance of these facilities to the safety of the community, it is critical that an emergency lighting system be efficient at all times, as well as centrally and, if possible, remotely controllable in an easy and intuitive way.
To meet the unique nature of an emergency lighting system, DALI-2 lighting provides best-in-class solutions for engineers and installers.
Reasons to Choose a DALI-2 Lighting Management System
In the domain of lighting automation, the use of the international DALI-2 (Digital Addressable Lighting Interface, second edition) protocol allows lighting devices to communicate with each other and with the lighting control systems for a more efficient and flexible management of the entire system. In other words, it makes it possible to control LED lamps and other lighting devices in a smart way, including self-powered emergency lights equipped with appropriate DALI-2 protocol drivers..
The DALI-2 protocol goes beyond the previous DALI standard and provides:
- Individual and real-time control of each individual lamp
- The adjustment of light intensity, color and color temperature
- The creation of customized lighting scenarios
- The reduction of installation, maintenance and operation costs
- Energy savings
- Enhanced security and reliability through advanced communication encryption.
The international standard DALI-2 protocol also allows for the implementation of self-powered emergency light control in Lighting and Building Automation systems.
A Lighting Automation system deployed with the DALI-2 standard, such as Duemmegi’s DUELUX System, enables lighting devices (including emergency lamps) to communicate with each other and with the control systems, for a more efficient, flexible and secure management of the entire system, which can also be fully controlled remotely.

Duemmegi's DALI-2 Certified DUELUX BUS System: Secure, State-of-the-Art Building with the Click of a Button
Duemmegi’s DALI-2 certified DUELUX BUS System provides all buildings (schools, hospitals, warehouses, etc.) with the capability to implement their own emergency lighting by controlling the entire system both locally and remotely, in a quick and intuitive way.
Building emergency lamps can be self-powered, which is a requirement for them to operate in the absence of power. They are usually located in strategic places such as corridors, stairways, emergency exits, and other important areas of the building to ensure the safety of the occupants. The status of the batteries, as well as durability tests and function tests, can be controlled directly from Duemmegi’s DALI-2 Controller.
The DALI-2 controller (DLCP module) – via the BMS supervisor – provides the ability to set specific parameters in the emergency lighting system (emergency level, rest stop identification, etc.) making it possible for the system to trigger specific procedures, such as function tests and battery life tests that make the lamps autonomous.
Duemmegi's DALI-2 DUELUX System: All Emergency Lighting always under Control
Duemmegi’s DALI-2 DUELUX system allows engineers and installers to implement an emergency lighting system consisting of lighting fixtures meeting the DALI-2 standard. In addition, the following 4 types of self-powered emergency lamps can be used (according to IEC Standard 62386-202 “Self-contained emergency lighting – Device Type 1”):
- Type A: Switched maintained dimmable control gear: In addition to emergency functions, it operates as a dimmable control gear
- Type B: Switched maintained non dimmable control gear: In addition to emergency functions, it operates as a standard control gear but only in ON-OFF mode
- Type C: Maintained control gear: Always on whether mains power is present or not; does not allow light level setting or configuration commands
- Type D: Non maintained control gear: Lights up when mains power is absent, turns off when mains power is present; does not allow light level setting or configuration commands
DUELUX DALI-2 Emergency Lighting: The Best for Safety – Now
Emergency lighting is mandatory in workplaces, high-risk environments, tourist accommodations, businesses, public entertainment venues, and all school buildings and kindergartens.
The international DALI-2 standard integrated into Duemmegi’s DUELUX system also allows self-powered emergency lamps to be controlled in third-party Lighting Automation systems and in all of the above-mentioned environments, making it easier for engineers and installers to work in the emergency lighting domain.
The DUELUX system has also been successfully implemented in existing facilities, such as the offices of the Milan headquarters of the Telepass group, Italian leading company that makes transponders with which it is easier for drivers to pay motorway tolls, park in affiliated car parks and other mobility services. There, Duemmegi’s DLCP controllers, which are DALI-2 certified like all products in the DUELUX line, control all self-powered emergency lamps.
