I've never used a fail safe solenoid door strike.  That's not meant to imply
they aren't popular.  Access control was never a big part of our business.

Why?  The solenoid strike doesn't prevent the user from exiting.  I wonder
if we're not talking about two different animals.  By "strike" I mean the
part that is attached to the door frame.  In it's normal (non-energized)
state it behaves like any normal strike plate.  The door can be opened from
within by turning the knob.  From the outside a regular key can open the
door.  Under power the keeper is released and the door can be opened from
the outside without a key.

Similar rules apply here as well but solenoid door strikes are generally
accepted without special door releasing devices because the door can still
be opened in the normal manner with or without electrical power.
