11 1 of 22 3/16/ :50 AM Public Comment No. 24-NFPA 17A-2015 [ Section No. 4.2 ] 4.2 * Detectors. Detectors shall be listed devices that detect heat Detectors shall be used for automatic actuation of fire-extinguishing systems Fire-extinguishing system releasing mechanisms shall be actuated by mechanical, electronic, or pneumatic detectors Detectors for actuation of fire-extinguishing systems shall be mechanical spot type, electronic spot type, electronic linear, or pneumatic linear Detectors shall be listed to UL 33, Standard for Heat Responsive Links for Fire-Protection Service, UL 521, Standard for Heat Detectors for Fire Protective Signaling Systems, or equivalent standards for listing heat responsive devices for fire protection service Where mechanical, electronic, or pneumatic heat detectors are installed to actuate listed pre-engineered fire-extinguishing systems, the heat detectors shall be selected, spaced, and installed to actuate the listed fire-extinguishing system when a fire occurs within the hazard area Detectors shall be permitted to be connected to a detector control panel Detector control panels shall be located so that inspection and maintenance activities are facilitated and interruption of protection is held to a minimum Detector control panels shall not be located where they can be rendered inoperable or unreliable due to mechanical damage or exposure to fire Detector control panels shall be permitted to have latches or locks to secure them from malicious or inadvertent tampering. A Heat responsive devices are often listed or categorized by temperature rating and other factors which have a bearing on their intended use. Selection of these devices for listed pre-engineered extinguishing systems should be based on their anticipated use with components of the listed fire extinguishing system. An important factor in proper selection of detectors is whether the fire-extinguishing system is actuated mechanically, pneumatically, or electronically. A Detector control panels are cabinets that often house microprocessors, electrical terminals, batteries, light emitting diodes, relays, fuses, and other electronic equipment. Detector control panels are used to interpret the output signals from detectors and cause releasing circuits to actuate the fire-extinguishing system. Currently there is no requirement for heat detectors to be used for system actuation. System actuation should be by heat detection devices and there should be requirements in NFPA 17A.

Substantiation of first draft change was based on intent to improve correlation between NFPA 17A and 96.

This standard is prepared for the use and guidance of those charged with the purchasing, designing, installing, testing, inspecting, approving, listing, operating, or maintaining of pre-engineered wet chemical fire-extinguishing systems in order that such equipment will function as intended throughout its life.

29 19 of 22 3/16/ :50 AM Public Comment No. 23-NFPA 17A-2015 [ Section No ] A secondary filtration or air pollution control unit, whether or not it includes an ignition source, shall be protected either with a separate automatic fire suppression system designed to operate simultaneously with the activation of the automatic fire suppression system protecting the ventilation hood(s) being served or with a single automatic fire suppression system that protects both the secondary filtration or air pollution control unit and the hood(s) being served. I believe this paragraph was inadvertently left in as the Committee Statement for Public Input No. 38 states "This subject is adequately addressed in NFPA 96 and no longer needs to be in NFPA 17A."

30 20 of 22 3/16/ :50 AM Public Comment No. 2-NFPA 17A-2015 [ New Section after ] TITLE OF NEW CONTENT Type your content here...periodic System Recertification (1) An AHJ witnessed recertification / retest of the entire system shall be conducted every 5 or 6 years. If the AHJ does not require their presence during the retest/recertification,the authorized distributor shall furnish the owner and AHJ with a document indicating that the recertification test has been performed. A authorized representative of the property shall also provide a document attesting to the performance of the test, providing names of all attendees.test results shall be provided to the local AHJ and owner. Test results shall be permanately posted alongside the system. (2) A Flow test shall be conducted every 5/6 years confirming that the piping/nozzle network is unobstructed and free of debris, grease, solidified extinguishing agent. Manufacturers shall supply the industry with mimimum quantity of extinguishing agent for each nozzle type, for comparisson to retest results. Manufacturers to supply minimum quantity of wet agent by weight of water or volume of minimum liqquid.a flow test shall be conducted using water as the flow test median. Quantity of water collected during flow test shall be compared to the minimum liquid requirements. All nozzles must achieve at least the minimum manufacturers allowable liquid quantity. (3) Recertification shall include a confirmation that all appliances originally filed and approved have not changed location, size, manufacturer or type and that all appliances, hood,duct and plenumn are fully protected meeting the original installation requirements. If a manufacturers has updated or made a addendun for a nozzles coverage, this change shall be provided to the AHJ and industry; the most current nozzle coverage shall apply. (4) All detection, activation and manual mechanical system shall be visually examined to assure that no visable signs of grease, debris, dust willl impair the operation of the system.a full funtional test of the system shall be performed. (5) All mechanical and electrical detection, fuel and appliance shutdown and releasing systems shall be fully tested in compliance with original installation procedures (6) A nitrogen or air test shall only be performed on an original installation or after a systems extinguishing system piping and detection system have been replaced in its entirety. The recommendation is made with the intent of maintaining and assuring the initial extinguishing system design qualities' are not reduced or compromised due to continuous use, neglect, lack of maintenance and aging of the fire suppression system. Statistically the wet chemical, "kitchen fire extinguishing market" has a large number of insurance claims, due to lack of proper maintenance, clogged piping, and dirty nozzles, and customers who refuse to re-pipe systems due to appliance being relocated on the cooking line. It is a known fact in the industry that grease is drawn into the agents suppression piping through the nozzles(lack of caps) Over time and the constant heating and cooling of the pipes collects grease internally and become clogged with grease impairing the flow a agent to the nozzle. This recommendations is similar to the all the requirements in NFPA 25 for sprinkler systems, assuring that all aspects of the sprinkler system will function as initially intended. A nitrogen test should only be performed on a system when the installer is fully aware that he/she can guarantee that there is no grease or debris in a piping configuration. Otherwise this is no different than a person whose has multiple blocked arteries,just not fully. The flow test validates and quantifies the systems ability. The need for the AHJ involvement is to assure the introduction and performance of the test. First Revision No. 8-NFPA 17A-2015 [Section No ]
