How to use the emergency door opening button?

The following is a common panic button list (the glass breaking button pops up and then manually presses it in):

The red panic button is a fire alarm button, a pair of signals are connected to the alarm, and there is a docking fire pump.

The green panic button is the emergency exit button of the entrance guard, which is connected to the entrance guard or power lock and can add an alarm.

The yellow emergency button is an emergency fire button, usually a glass outer box. After pulling down the internal handle for 30-60 seconds, directly control the fire extinguishing equipment to work and release the fire extinguishing agent, which should also be connected with the alarm and generate an alarm at the same time.

When it is forbidden to open the door, the white exit button can't open the door, and the green button can open the door immediately, but you should call the police to remind the security personnel.

Press the green button directly in case of emergency (non-fire).

If there is a fire, please press the red fire button you can see at any time.

If the system design is standard, the entrance guard will be opened immediately after the fire alarm starts (signal transmission is still delayed).

If you don't open the door in the case of access control, please press the green button.
