Right. When the batteries died the system tripped. If the contractor had left the sprinks intact, it would have been just another maintenance call. The sprink they failed to neuter was just a clue which made me believe it wasn't deliberately a deluge system. The important thing though, is the absence of major loss, in spite of the things that went wrong. Ed Vining 4819 John Muir Rd Martinez CA 94553 925-228-8792 Cell 925-787-0465
