Question

Is it the intent of Section 911.1.5 to provide
individual control of all building air handling
systems from the fire command center in all
modes of operation, i.e. should the controls be
capable of over-riding the fire alarm functions
of the building (shutdown)?

Yes. This section is separate and distinct from section 6
which addresses smoke control system panels.

Commentary

Note: This language is also contained in the FFPC NFPA 1 section 11.9.5. The design professional should consult with the local Building Official and Fire Official regarding the need for override control of each separate HVAC system. The local Fire and Building Official, in consultation with the design professional, may determine that the need for this level of control for all air handling systems is not appropriate based on the hazard and system design.
