COURSE DESCRIPTIONNFPA 92 applies to the design, installation, acceptance testing,operation, and ongoing periodic testing of smoke controlsystems. As the industry standard, it is important for designers,installers, and code enforcers to be familiar with the document,its history, and remain abreast of upcoming changes.www.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

LEARNING OBJECTIVESAt the end of the this course, participants will be able to:1. Interpret the background and recent history of NFPA 92 and smoke controlsystems.2. Comprehend smoke control design objectives, design approaches, and designcriteria.3. Determine testing procedures and required documentation for smoke controlcommissioning.4. Understand how proposed changes to the 2018 edition can affect new designs andinstallations.www.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

WHAT ARE SMOKE CONTROL SYSTEMS?“Engineered system that includes all methods that canbe used singly or in combination to modify smokemovement.”NFPA 92 §3.3.23.5www.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

SMOKE CONTROL SYSTEMSContainmentManagementA smoke control method that usesmechanical equipment to producepressure differences across smokebarriers.A smoke control method thatutilizes natural or mechanicalsystems to maintain a tenableenvironment in the means ofegress from a large-volume spaceor to control and reduce themigration of smoke between the firearea and communicating spaces.This Photo by JohnKlotewww.jensenhughes.comThis Photo by JohnKloteCopyright JENSEN HUGHES.

WHAT IS TENABILITY?Tenable Environment: an environment in which smokeand heat are limited or otherwise restricted to maintainthe impact on occupants to a level that is not lifethreatening.This Photo by NPSwww.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

TESTING Physical inspection Component tests Acceptance testing Testing under four modesDoor opening forcemeasurementsControls activationOperation of componentsIn accordance with its owndesign parameterswww.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

TESTING – LARGE VOLUME SPACES Identify all areas to bemeasured Verify: Operation of componentsMeasure exhaustcapacities and airvelocitiesMeasure door openingforces Where applicable,measure pressuredifferentialswww.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

TESTING – SMOKE CONTAINMENT SYSTEMS Pressure testing Force testing Various types ofpressurized systems: StairwellElevator shaftLobbyVestibuleZonesArea of refugewww.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.

CHANGES TO 2018 - UUKL Weekly self-test functionality of the smoke controlpanel New addition allows for bypass of actual activationupon AHJ approval Testing plan required; no less than semi-annually Affects to commissioning process: Must be UUKL listedOR have AHJ approval and test planwww.jensenhughes.comCopyright JENSEN HUGHES.

CHANGES TO 2018 - TENABILITY Added in Appendix M Tool to aid in the design Affects commissioning: sets parameters for measurementduring acceptance testing Should make it more uniform across different jurisdictionswww.jensenhughes.comCopyright JENSEN HUGHES. All rights reserved.
