2 1 of 52 11/16/2016 4:26 PM First Revision No NFPA [ Section No ] Air Sampling Type Detector. A detector that consists of a piping or tubing distribution network that runs from the detector to the area(s) to be protected. An aspiration fan in the detector housing draws air from the protected area back to the detector through air- sampling ports, piping, or tubing. At the detector, the air is analyzed for fire products.

Submitter Information Verification Submitter Full Name: SIG-IDS Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Thu Jul 28 19:51:55 EDT 2016 Committee Statement Committee Statement: Response Message: The existing text dates back to the days when smoke alarms had mechanical adjustments for sensitivity. In looking at UL 217, the requirement is interpreted as a mechanical adjustment in Section of the eighth edition. As currently written in NFPA , the requirement may create confusion if it is viewed within the context of high sensitivity aspirated detectors, which have sensitivity settings outside of the normal UL range of 0.5 to 4%/ft. Aspirated detectors have a number of very high sensitivity threshold settings that may not differ by the amount required in Public Input No. 373-NFPA [Section No ] Ballot Results This item has passed ballot 26 Eligible Voters 2 Not Returned 23 Affirmative All 0 Affirmative with Comments 0 Negative with Comments 1 Abstention Not Returned Hall, Robert A.

This change is a result of that task group's efforts. Additionally, the task group proposed a complete re-write of section which the Technical Committee accepted with revisions. The SIG-IDS Technical Committee provides additional guidance for air sampling-type smoke detection systems in NFPA 72. New subsections are introduced to categorize the different sections that apply to an installation or application : Adds criteria for performance based design, ties back to and manufacturer s published instructions. In absence, application would otherwise be limiting : Relocate under new general subsection, edited to include the word smoke after Air Sampling for consistency with the section title : New language intended to prevent use of improper filtration media that may hinder system performance : Relocate to new subsection for proper categorization : Relocate to new subsection for proper categorization, edit language for clarity. Sound / principles not specific.

29 27 of 52 11/16/2016 4:26 PM : Relocate for proper categorization, additional requirements are added for clarity of calculated performance verification : New language to ensure modelling programs be specific to the manufacturer s equipment and set criteria that the program be listed : Relocate to new subsection for proper categorization : New language to avoid challenges with respect to identifying sampling ports to avoid damage, non-engineered alterations, and points where maintenance may be required : New language to not unnecessarily burden system capacity or performance by placing a test point at accessible locations. This does not remove the requirement to meet 120 sec from last sampling port in fire zone. A : Add appendix material to provide additional guidance with respect to benchmark test point : New material to prevent damage to pipe from non-compatible chemistries and/or blockage of sampling ports as a result of painting in the field New language to address suitability of sampling pipe network with respect to the environment in which they are installed : New language extending requirements to capillary tubes, also, acknowledges permissible use of capillaries and requires that they be included in calculations : Relocate to new subsection : New language to prevent systems from not performing their intended function. Pressure differentials, if not within manufacture's published guidelines results in systems performing unpredictably : New language to assure proper methods and materials are used as it relates to support of air sampling pipe distribution networks : New language to ensure that the detector selected is suitable and listed for duct application and to improve clarity of installation for intent of performance. Response Message: : New language to provide guidance for application in electrical cabinets noting requirements for placement of ports for interception of smoke.

Sides, Michael D. Swerdin, Mark Waite, David Negative with Comment Marrion, Chris Section needs to be revised and updated. This should include addressing such items as: Section replace with Carbon monoxide detectors shall be located based on an assessment of the space and environmental conditions and adverse environmental conditions will be assessed and mitigated. If carbon monoxide cannot be provided, other mitigation measures will be implemented to address the carbon monoxide hazard. This section currently sounds like it allows not providing CO detectors if the environment is adverse (garage in wintertime) but doesn t indicate that other alternate measures should be taken This section needs more detail as is unclear where detectors are needed and appears to be overly onerous w/potential limited beneficial impact. This should include updating terms that are vague centrally located, every HVAC zone of the building, etc delete permanently installed and replace appliances with equipment. This doesn t address other equipment that may not be permanent that is likewise a hazard add sleeping rooms and areas all of the design sections should be consolidated and clarified. There also appears to be discrepancies in the various requirements e.g , , etc add Carbon monoxide detector designs shall take into consideration the location of the carbon monoxide producing source, its exhaust equipment including accounting for leakage in equipment and ductwork, its potential movement throughout a space as well as the building both horizontally and vertically, the impact of hvac equipment on transporting it throughout the building, etc. and locate carbon monoxide detectors to address the hazards within the overall building appropriately revise to state carbon monoxide detectors shall be installed as per their listing. It currently appears as if those conditions will make it ok not to install detectors. Eg. a mechanical room, garage, etc. that goes below freezing in winters, boiler rooms, etc this should also address code requirements and what they are requiring in relation to this so that they are coordinated.

45 A (1) Carbon monoxide detectors are located on the ceiling above permanently installed fuel burning appliances because of the buoyancy of the heated combustion gases as compared to normal ambient temperatures. Detectors should be located as close as practical to the permanently installed fuel burning appliance consistent with considerations of detector accessibility, sources of detector contamination, and nuisance sources. Siting considerations can include transient backdrafting spillage of flue gases during startup and ventilation supply or exhaust vents. A (2) The purpose of detectors centrally located on every habitable level is to detect the migration of carbon monoxide from permanently installed fuel burning appliances and other sources of carbon monoxide. Other sources of carbon monoxide can include vehicles or other equipment that uses an internal combustion engine, barbecue grills, propane operated equipment, and systems used to generate hydrogen. Detector location and spacing should be based on an engineering evaluation that considers potential sources and migration of carbon monoxide. HVAC systems should be considered in the locating of carbon monoxide detectors because the HVAC systems provide a good means of mixing and the migration of carbon monoxide. Other considerations when locating carbon monoxide detectors are areas with closed doors and rated demising walls, which can isolate or separate areas within HVAC zones. Additional information for the location of carbon monoxide detectors is available in the Fire Protection Research Foundation (FPRF) technical report, Development of a Technical Basis for Carbon Monoxide Detector Siting.
