German to Dutch Law/Patents Construction / Civil Engineering Maintenance obligations in building lease

"Darüber hinaus sind die technischen Anlagen (Sprinkleranlagen, Lüftung, Sicherheitsbeleuchtung, EAN) für den Einbau einer abgehängten Mineralfaser-Decke herzurichten"

Hello,

Here's a sentence in a contract for the lease of a retail store in a shopping center.
It has to do with the tenant's obligations.

What stumps me is the "EAN", which in this context cannot refer to a European Article Number.

Any suggestions are welcome!
Thanks for your trouble.

André
