Do Automatic Doors Work When There Is A Power Cut?

How to operate automatic doors without a power supply.

One question that crops up time and time again when customers of ours are considering having automatic doors installed on their premises, is, “what happens if there is a power failure?”

Understandably, operators are concerned about having building users trapped inside, stuck behind a sliding door or a swing door that won’t open. Even more alarmingly, what would happen during an emergency situation when the building needs to be evacuated?

We’ve decided to give out some information to help you understand how automatic doors operate, and what options are available to maintain safety should they lose power.

Uninterrupted Power Supply (UPS)

Uninterrupted Power Supply (UPS) is a battery unit that can take over the operation of an automatic door in the event that it is cut off from the mains electricity. The UPS means that doors remain operable during business hours. Importantly, the building will also remain secure if the power cut should occur overnight.

Fail Safe

This system means that the door will only lock when it has a power source. The maglock (magnetic door lock) requires power to operate. In the event of a power failure, either: the UPS will take over, or the maglock will release and the door can be opened manually.

The fail safe can be integrated into fire detection systems, so they will automatically open and remain open. This makes them a great solution for ensuring the security and safety of a building.
