I have a question about protection of sprinklers in windows specifically for a connection of a basement parking garage and a first level mall commercial space.
NFPA 101 accepts that there is a connection between both occupancies, but there must be compartmentalization of 3-hours without automatic sprinklers and 2-hours with automatic sprinklers. In this case, we have an escalator from the basement up to level 1, as shown below:
Can we consider this to be compartmentalized with glass and sprinklers on both sides of the glass?
Do the access doors have to be 1-1/2 hour, our could they not have any fire resistance if I have sprinklers on both sides?
This project is under NFPA 101 (specifically Table 22.214.171.124.1 for separation between occupancies), NFPA 5000, and NFPA 13 (9.3.5/19.4.3 for sprinkler protection of windows).
