Which Recessed Escutcheon?
I have run into this issue many times in the last few years. What recessed escutcheons can be used with what pendent sprinklers? The short and most correct answer is: Recessed sprinklers are listed for use with a specific escutcheon. i.e., Order the recessed escutcheon form the same manufacturer as the pendent sprinkler. All the manufacturers indicate that recessed sprinklers are to be ordered as a unit, even though most ship the escutcheons separately.
The reason this is such an issue is the number of independent suppliers of fire protection products who sell recessed escutcheons. I know a lot of fire sprinkler companies keep these generic escutcheons on the shelves and use them with what ever pendent sprinkler they got the best price on that week. It eliminates an inventory headache and helps reduce costs. But what is their liability?
After a lot of checking on the web I found only one manufacturer of escutcheons which was UL listed. ARGCO is UL listed File EX4170 and their product data states :
There is no possibility of a sprinkler head failure due to ARGCO escutcheons. It is no longer a warranty issue, since UL announced, “Installed properly, the product cannot affect sprinkler head operation.”
So while the possible liability of installing pendent sprinklers with generic escutcheons might be small, It would seem prudent to at least use a manufacturer such as ARGCO which provides a UL listing and would stand behind their product.
I for one, however, will continue to specify and order escutcheons from the same manufacturer.
