Please note on the plans the added eleven (11) pull stations. The plan only showed 1 pull station for the entire building. Per NFPA 72:5.12.6 pull stations are required within 5 feet of the exit doorway opening at each exit on each floor. I have indicated on the plans the locations that the pull stations are required. Note: The locations are not intended to be the exact location to mount the box but rather to indicate the exits that require them.
Also ensure that the pull station in the lobby is installed to meet the 5' requirement. On the plan it appears close.

It appears to be a printing error, however please ensure that the horn strobe on the second floor is moved out of the break room into the hallway per the engineers layout.
