DALI Part 202 New Edition Unfolded: Here are the Changes You Must Know!

Buildings and commercial spaces are prone to many unprecedented emergencies. Preparing for the worst is, therefore, always a proactive step. 

Emergency lighting is one of the effective means of this preparation. Governments worldwide are making emergency lighting compliance mandatory for buildings and commercial spaces. Manual testing and unreliable reports often affect the efficiency and purpose of emergency lighting. The answer lies in Smart Emergency Lighting with DALI Part 202

Recently, the International Electrotechnical Commission (IEC) published edition 2.0 of Part 202 of IEC 62386 (DALI Part 202). 

Let’s take a closer look at DALI Part 202 and its new edition in this blog. 

DALI Part 202: An Overview 

DALI Part 202 specifies the control gear requirements for a self-contained emergency system for AC or DC power supplies. In self-contained emergency lighting, the batteries are placed next to the luminaire, giving each luminaire its own power source. This arrangement helps the luminaire to switch over immediately to the battery placed nearby. 

Part 202 specifies four types of self-contained emergency devices.

DALI Part 202: The Major Changes in Edition 2

 The first edition of DALI Part 202 was released in 2009. It is published in parts to facilitate future amendments and revisions. Edition 2 of DALI Part 202 contains some technical revisions.  

Automated testing was optional earlier. The latest edition has made it mandatory. This step can increase the prospects of smart emergency lighting systems. The change has made monitoring, managing, and ensuring occupant safety simpler. It gives the user the conveyance of disabling the hardwired switch operation. 

A new memory bank is added in the latest edition. It allows the control gear to record more information and give detailed insights to take more proactive steps before, during, and after an emergency situation. 

The installation inhibit feature added in the second edition help you to avoid battery wear-out during installation to save project cost. 

Deep discharge prevention is another new feature brought by the new edition. A deep discharge causes the battery to swell and slowly destroys its performance. It occurs when the capacity of a cell is exhausted. 

Extended-duration tests are now allowed in the latest edition to ensure sufficient battery backup (more than the maximum capacity) during an emergency.
