I understand what your saying.  However, in Toronto, the inspectors look for
the local release, and when the fire guys (which I'm not one of) put in the
pull stations for us they leave a 2nd wire off of the pull station aux.
contact for us to tie our mag pwr through.  Maybe my wording wasn't the
best, but one contact on the pull station triggers the fire alarm (which
should drop all the building mags anyways) and the 2nd conatct locally cuts
the pwr directly to the mag the pull station is beside.  This elimates any
type of delay or system failure as the door can be opened right away as the
mag has no pwr.  A pull station somewhere else in the building without a mag
door beside it would not need to have this done.
