Which type of sprinkler would you prefer for Health Care facility or Hospital building if cost is not a constraint?
If you can meet all head spacing & head clearance rules, that would be the concealed.
There is a lot going on at ceiling level in X-Ray & Surgery suites that could conflict with a concealed head.
For sanitary reasons I would prefer concealed if possible
I prefer the visible type . I think the visibility is an important condition for people who occupy a building : It provides a sense of security ( aesthetics is for artists , heh) The same situation for maintenance personnel , who are not familiar with fire systems especially helps with concealed type , as they may cause them damage or obstruct them involuntarily in the development of their work.
I have been in Life safety in Heath Care for over 15 years. Every Joint Commission inspection we get dinged for dust on the sprinkler head or the ceiling tile not cut properly and there is a gap between the head and the tile so I am for concealed.
Since there is no difference in the coverage of a standard Concealed or standard recessed sprinkler, this is mostly an aesthetical decision, understanding the fact that a concealed sprinkler requires more clearance above the ceiling than the recessed sprinkler does, and as previously stated this can be a problem in a hospital environment where the space above the ceiling is limited in most cases, (you should also consider the possibility that space may be available in some areas and not others due to structural features, ductwork, medical gas systems, etc.) which might cause you to have to use concealed in one area and/or recessed in another. If adequate space is available, it comes down to aesthetics, in which case, I would consult the architect or other building representative. i.e., interior decorator.
I agree with you Lisa and kwilson..
I do not like concealed escutcheons. I have to supply and install replacement esc. I find it is difficult find concealed esc, and would like to see a requirement to have extra esc, no matter if they are recessed, canopy or concealed, on the premises.
There are oversized esc that will hide the gap between the ceiling and the escutcheon. We call them "oops!" esc, and they are available in chrome and white.
Doesn't matter to me
