We do this around here some. when a compressor fails or something along
that line. They DO NOT have the capability to trip an alarm system when it
is this way. The pressure port for the Alarm Switch comes off the
intermediate chamber, That does stay wet like this. We "advise" them they
will need to do a Fire Watch while the system is tripped wet.

Well there is "THAT" word ass-u-ming on a sprinkler forum... From what I
have seen not many dry alarm valve clappers can be reset externally, I
think Victaulic and Tyco have one that can be. I would be willing to
venture a guess the Alarm Line valve is turned off.
