fire protection improvement

fire protection improvement

fire protection improvement

(OP)
i am having hard time designing for fire protection improvement for normal open doors..i am looking for devices which will not allow entry to the where fire or smoke was detected but occupants can exit and can function either way..it is a two door swinging type..PLEASE HELP.....

RE: fire protection improvement

Questions:

1) Are these doors in an egress path?
2) Are these doors penetrating a fire barrier or fire wall? If so, what is the fire resistance rating?
3) Is the building protected by automatic sprinklers?
4) Is the building in the U.S.?

I've never seen a fire rated door assembly as you have described. The fundamental question is once folks have exited from a compartment or area that is involved in fire, why would want them to re-enter this area?

Please post more information

RE: fire protection improvement

I think you want and electrified lockset that will provide free egress from the secured side out, and remain locked from the unsecured side.  Have the door held open with a magnetic door holder controlled by the fire alarm system, so that it will release upon smoke detection.

RE: fire protection improvement

Holding the door locked from the non-fire side will keep out the fire fighters.  Not a good idea.  Electric lock systems almost always unlock in case of fire to allow firefighters in.

RE: fire protection improvement

I hope this isn't an off-topic. Please help a layman out..

I'm doing a translation into English, the document is Technical Specifications for a Fire Protection System of a high-rise building.  I cannot find the proper name for the waterpipe that's used for fire-fighting purposes.  Is it fire watermain? Fire waterline?.. (Not the little sprinklers and stuff.. the whole kit'n'caboodle system).  Many thanks :)
