See if this is what you're after:
NFPA-13, 2007 edition, 8.7.3.1.7 states:
Where sidewall standard spray sprinklers are installed to protect areas
below overhead doors
within ordinary hazard occupancy spaces or rooms, protection area and
maximum sprinkler
spacing for light hazard as specified in Table 8.7.2.2.1 shall be
permitted under the overhead
doors.

Quick question:
When you use a single horizontal sidewall sprinkler to cover the area
under
an open overhead door would you still use the spacing for whatever
occupancy
is below? If, let's say, this is an Ord Group II hazard this would limit a
sidewall sprinkler to 10'x10' - and if I have a 10 ft. door that's 12 ft.
wide it would take two sidewall sprinklers to cover uner the door. If this
is the case how does this fit into extra hazard occupancies which does not
allow the use of sidewall sprinklers?
