How are power outages or network failures handled by a multi-door controller?

Question

Accepted Answer

Multi-door controllers often have built-in backup power options, such as battery backup or uninterruptible power supplies (UPS), to ensure continued operation during power outages. Additionally, some controllers have local memory to store access events during network disruptions, which can later be synchronized with the central system once connectivity is restored.
