I'd have to also suggest getting the manufacturer involved, even if its possibly a coat hanger problem.... but ...
I'd be curious to know if this property has a fire pump ? (jockey or pump surge) Is it by chance a looped or gridded system ? (Missing or malfunctioning pressure relief valve) The 11:30 PM time might point to a city pressure surge from decreased usage on the grid. What time of days were the other activations? Any obvious, or no-so obvious, ambient temperature flucuations like those HVAC split units or in wall units blowing past the head? Were all the rooms occupied at the time of activation ? I dont know if these have been already looked at but its the first things that come to mind. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/mailman/listinfo/sprinklerforum To Unsubscribe, send an email to:[EMAIL PROTECTED] (Put the word unsubscribe in the subject field)
