Blue Rise is right, most would be a simple magnetic field device instead of a selinoid driven system.
First off is cost. They are infinately cheaper, and can hold a lot of weight before being forced open. (Governed by the magnetic field).
They are quick to activate, as an electro magnetic field is almost instant. (Close enough, its measured in trilliths of a second!). With the only disadvantage being brown outs and power failure. (Battery back-ups will hold for a time).
Compared to selinoid driven, which has a mechanical factor to it, which makes it slower to engage, disengage. (Measured in thounsandths of seconds). Are expensive to operate (takes much more power to retract the bolts, and hold them closed). Not to mention the increased costs of both the door and surrounding walls and frame. However, you are not getting through them without specialized tools, and a lot of time, or catastrophic damage.
These things are used on things you DON'T want opened, unless you HAVE to open it... So not your standard employee door.

But, in the world of SR, the selinoid door may show up more then you think..... depending on just how cruel your corps are.

On a side note for you more technical minded out there, and as some posted some building codes, know that those codes are incomplete.
"Hospitals" is a general term for any structure that provides surgery, heathcare and long term recovery. There are more specialized rules for more specialized care facilities.
So, depending on the emergency, doors will open or lock as needed to contain said emergency. This would all be controlled from a master system that ties a number of services for the building, such as HVAC, fire control, door control, security alarms, various monitors, transmitters, indicators and other specialized functions.
For example, in many labs that operate with contagious agents operate under a double door negative pressure environment. This is to stop any agents from leaving the area as when a door is opened, the positive pressure outside "blows" the agent back into the room.
However, in the event of a fire: the first door SEALS (even with people inside) and the second door can be opened, creating a "fire break". Mean while, HVAC to the room is completely cut off, and suppression is engaged.
Guesome for the workers, yes. But those proceedures aren't there for their safety.... but for everyone else.
Same goes for most sensitive buildings..... what happens is determined by the control systems laid out for the building.... HOWEVER: a fire alarm is generally the only thing that ever overrides a building lock down. (Unless like in my above example, the fire protocol dictates something else).
Not such a bad idea to bring that decker along, and find that building spider now is it?
