A bit of background information, I'm a new FM and am performing inspections in an area that has been highly neglected by previous inspectors. It seems that I'm having to come back and correct many things that were overlooked or never addressed: I am in Indiana, and am following 2006 IFC w/ state amendments; I am working on a report for a large, 50k+ sq. ft. M occupancy that was built circa 1993, has changed business ownership 3 times in the past but not changed occupancy classification nor have any structural changes been made. The most recent change of occupant occurred about 4 years ago.
Technically speaking, I am aware that I should be following the code that was adopted at the time the structure was built considering no alterations have been made to the structure; however I have no idea what code was in existence at that time, and believe the modern code may be more stringent. Most local inspectors follow the latest adopted code unless challenged by the occupant.
One of the items that I'm working on with this occupant, is the use of locking hardware on exits, a common issue. One marked exit has a surface mount bolt that I will require to be removed per 1008.1.8. However;
My questions are the following; are twist latch locks (forgive my lack of proper terminology here) allowed on horizontal automatic doors? Some of the doors have their sensors turned off to prevent them from automatically opening, additionally they have stickers on them indicating that the doors must be unlocked during occupancy. I'm assuming that these are acceptable, given the age of the structure.
Second, am I correct in understanding that any exit with exception to the main entrance (given exceptions) may have additional locking hardware, so long as it is interconnected, ie,the single motion of an ADA handle or panic bar will unlock all other hardware simultaneously?
Lastly; double cylinder locks are unacceptable on any door configuration, including the main entrance? Are twist locks acceptable on main entrances if they are not in operation during occupancy?
I appreciate any opinions and insight. Again, forgive my lack of knowledge and experience, I'm wanting to expand both.
