(1)909.1 Scope and purpose. This paragraph applies to mechanical or passive smoke control systems when they are required for new buildings or portions thereof by provisions of the building code as listed in rule 1301:7-7-47 of the Administrative Codeor this code. The purpose of this paragraph is to establish minimum requirements for the design, installation and acceptance testing of smoke control systems that are intended to provide a tenable environment for the evacuation or relocation of occupants. These provisions are not intended for the preservation of contents, the timely restoration of operations, or for assistance in fire suppression or overhaul activities. Smoke control systems regulated by this paragraph serve a different purpose than the smoke- and heat-venting provisions found in paragraph (J)(910) of this rule. Mechanical smoke control systems shall not be considered exhaust systems under Chapter 5 of the mechanical code as listed in rule 1301:7-7-47 of the Administrative Code.

The construction documents shall include sufficient information and detail to describe adequately the elements of the design necessary for the proper implementation of the smoke control systems. These documents shall be accompanied with sufficient information and analysis to demonstrate compliance with these provisions.

(3)909.3 Special inspection and test requirements. In addition to the ordinary inspection and test requirements to which buildings, structures and parts thereof are required to undergo, smoke control systems subject to the provisions of paragraph (I)(909) of this rule shall undergo special inspections and tests sufficient to verify the proper commissioning of the smoke control design in its final installed condition. The design submission accompanying the construction documents shall clearly detail procedures and methods to be used and the items subject to such inspections and tests. Such commissioning shall be in accordance with generally accepted engineering practice and, where possible, based on published standards for the particular testing involved. The special inspections and tests required by this paragraph shall be conducted under the same terms as in section 1704 of the building code as listed in rule 1301:7-7-47 of the Administrative Code.

(4)909.4 Analysis. A rational analysis supporting the types of smoke control systems to be employed, the methods of their operations, the systems supporting them, and the methods of construction to be utilized shall accompany the construction documents submission and include, but not be limited to, the items indicated in paragraphs (I)(4)(a)(909.4.1) to (I)(4)(f)(909.4.6) of this rule.

(a) 909.4.1 Stack effect. The system shall be designed such that the maximum probable normal or reverse stack effect will not adversely interfere with the system's capabilities. In determining the maximum probable stack effect, altitude, elevation, weather history and interior temperatures shall be used.

(b) 909.4.2 Temperature effect of fire. Buoyancy and expansion caused by the design fire in accordance with paragraph (I)(9)( 909.9 ) of this rule shall be analyzed. The system shall be designed such that these effects do not adversely interfere with the system's capabilities.
