Manual release
Most gate operators provide a manual release, but the method varies. The key must be available to the right people and the gate must be mechanically safe and practical to move by hand
A heavy or damaged gate can remain difficult to move even after the motor is released
Battery backup
Battery backup can maintain limited operation during an outage, but capacity depends on the system, battery condition, gate load and number of cycles
Batteries are consumable components. They need testing and replacement when their capacity has deteriorated
Plan the whole access sequence
Electric locks, maglocks, intercoms, network equipment and access controllers may each respond differently during a blackout. Restoring motor power alone may not restore the entrance
Critical sites should document who can release the gate, how emergency access works and what happens if the outage lasts longer than the battery capacity
Automatic gates and doors can cause serious injury. Keep clear of moving equipment and live electrical parts. If operation is unpredictable or unsafe, isolate the system where practical and arrange professional assessment
