NFPA 13 Section 188.8.131.52:
"Early suppression fast-response (ESFR) sprinklers shall not be used in buildings with automatic heat or smoke vents unless the vents use a high-temperature rated, standard-response operating mechanism."
ESFR sprinklers are designed to act fast and suppress the fire, the inclusion of a roof vent that opens up before the sprinkler activates could severely impact sprinkler activation both in terms of timing and location (as the moving smoke could activate a more remote sprinkler). If automatic roof vents are present, they should have a high-temperature rated standard-response operating mechanism to ensure that the sprinkler activates before the vent opens up.
Based on the above, am I correct to interpret smoke venting is not required with ESFR systems?
How do I go about handling smoke or heat vents with ESFR, or are they not necessary to begin with?
