Im helping a local electrical contractor bid a fire job and it has the sprinkler head requirement with shunt trip breaker arangement to shut off power when sprinkler activates. I have added an addendum that my firm and electrical contractor are held faultless indemnified if something goes wrong ,and i cited all the problems with this arangement including the fact that shunt trip breaker can and do go bad and fail to operate and occupant of elevator cab could become trapped, injured or killed .I included the article i did for Pa firemans magazine as well needless to say this turned a few heads. I do not see the sprinler head being used at this point after all the liabilties were raised. has any one else delt with this issue. and what was AHJ etc response.
