This is too simplistic. A lot of automatic door locks are just door strikes with a solenoid that is remotely actuated inside the door casing. In that model you can let people out of the building because the inner part of the door has a bar you can press that moves the door pin, which is how all door handles work normally, so there’s no “fail open” needed. You can get out, but you might not be able to get back in. |
