The clapper would have to be down to close water and pressure on the alarm switch which normally has no pressure against it. Plus, the high low switch (assuming it has one) would be in alarm due to 3-5 times the pressure (with water as opposed to air) on it. I don't think the external reset types will close charged and I know you have to open and reset the traditional style of dry pipe valve so unless you disable your monitoring switches; the answer is no.
How's that for long-winded? Tom GRS Hi Pete, If the system went wet then the pressure switch is activated and the fire panel should be in full fire. You would not be able to reset the alarm unless; I believe the system is drained. Also the low air alarm would keep the panel in trouble. This means if there is a fire the system would be out of service and not notify anyone in case of fire. Forum Members: If a dry pipe valve trips and "goes wet", is there any reason why you couldn't leave the system piping filled with water assuming that the weather is not cold enough to freeze it? I am assuming that the clappers have been reset externally and that the alarm connections remain dry since they don't seem to be having problems at this time. Why would they want to use an alarm valve in place in liew of just leaving the dry pipe valve? Thanks in advance.
