We are planning a new research library and have selected on/off
sprinkler heads for our fire protection system.  The sprinkler heads
will be used with a wet system.  We chose a wet system based on
reported maintenance problems with dry systems.

Recently, we learned that Australia is banning on/off sprinkler
heads because of leakage problems with ones that have been installed
there. We do know that there has been a history of leaks with two
manufacturer's on/off heads, but thought that the problem had been
corrected in their latest products.

Does anyone know of a library that has used on/off sprinkler heads
for the last 5-10 years, either with or without problems?
