What's the trick of electromagnetic lock without power?

Generally, the electromagnetic lock does not have a clear power prompt function, but when the power is insufficient or dead, the following situations or prompts usually appear:

1. Unable to unlock: after the electromagnetic lock is powered off, it cannot be unlocked normally. You may need to use a backup power supply to unlock the door lock.

2. Unable to lock: The electromagnetic lock may not be locked normally under the condition of insufficient power or no power. At this time, the door may not be completely closed or the door lock may not be locked.

3. Alarm prompt: Some electromagnetic locks may trigger the alarm function when the power is insufficient or dead, reminding users to pay attention.

If you find that the electromagnetic lock does not work properly or the above situation occurs, you can consider the following solutions:

-Check the power supply: ensure that the power supply of the electromagnetic lock is connected normally, and confirm whether the power supply equipment works normally.

-Charging or replacing the battery: If the electromagnetic lock is powered by a battery, please try charging or replacing a new battery.

-Check the wire connection: Check whether the wire connection between the electromagnetic lock and the power supply is loose or damaged, and ensure the connection is stable.

-Seek professional help: If the above methods cannot solve the problem, it is recommended to contact the electromagnetic lock supplier or professional technicians for overhaul and maintenance.
