We're doing work in an office building (happens to be a medical office building) and we're re-doing a single suite). Our strobes in that suite will be synchronized but the strobes outside the suite are on an older system and will not be synchronized. We're being told that we need to replace the strobes outside our work area. i.e. in the corridor such that they synch with those in our space. Of course, the corridor will need to be synched with all spaces it comes in contact with which is every single suite on the floor. THis strikes me as nonsense.
But even if we have treat this like a new facility and provide to the letter of the NFPA 72, isn't there a provision in there to be between two sychronized zones but not more than that. i.e. isn't it permissible to have an area where an occupant would be exposed to two but no more than two synchronized zones.
I thought there was verbage along these lines but can't find it, perhaps because it's not there. Can anyone help?
