General Procedures for Meetings

Use of tape recorders or other means capable of producing verbatim transcriptions of any NFPA Committee Meeting is not permitted.

Attendance at all NFPA Committee Meetings is open. All guests must sign in and identify their affiliation.

Participation in NFPA Committee Meetings is generally limited to committee members and NFPA staff. Participation by guests is limited to individuals, who have received prior approval from the chair to address the committee on a particular item, or who wish to speak regarding public proposals or comments that they submitted.

The chairman reserves the right to limit the amount of time available for any presentation.

No interviews will be allowed in the meeting room at any time, including breaks.

All attendees are reminded that formal votes of committee members will be secured by letter ballot. Voting at this meeting is used to establish a sense of agreement, but only the results of the formal letter ballot will determine the official action of the committee.

Note to Special Experts: Particular attention is called to Section 3.3(e ) of the NFPA Guide for Conduct of Participants in the NFPA Codes and Standards Development Process in the NFPA Directory. This section requires committee members to declare any interest they may represent, other than their official designation as shown on the committee roster. This typically occurs when a special expert is trained by and represents another interest category on a particular subject. If such a situation exists on a specific issue or issues, the committee member shall declare those interest to the committee and refrain from voting on any action relating to those issues.

Public Comment No. 24-NFPA 17A-2015 [ Section No. 4.2 ]

4.2

* Detectors.

Detectors shall be listed devices that detect heat.

4.2.1 Detectors shall be used for automatic actuation of fire-extinguishing systems.

4.2.2 Fire-extinguishing system releasing mechanisms shall be actuated by mechanical, electronic, orpneumatic detectors.

4.2.3 Detectors for actuation of fire-extinguishing systems shall be mechanical spot type, electronic spottype, electronic linear, or pneumatic linear.

4.2.3.1 Detectors shall be listed to UL 33, Standard for Heat Responsive Links for Fire-ProtectionService, UL 521, Standard for Heat Detectors for Fire Protective Signaling Systems, or equivalentstandards for listing heat responsive devices for fire protection service.

4.2.4 Where mechanical, electronic, or pneumatic heat detectors are installed to actuate listedpre-engineered fire-extinguishing systems, the heat detectors shall be selected, spaced, and installed toactuate the listed fire-extinguishing system when a fire occurs within the hazard area.

4.2.5 Detectors shall be permitted to be connected to a detector control panel.

4.2.5 .1 Detector control panels shall be located so that inspection and maintenance activities arefacilitated and interruption of protection is held to a minimum.

4.2.5 .2 Detector control panels shall not be located where they can be rendered inoperable orunreliable due to mechanical damage or exposure to fire.

4.2.5 .3 Detector control panels shall be permitted to have latches or locks to secure them frommalicious or inadvertent tampering.

A.4.2.4 Heat responsive devices are often listed or categorized by temperature rating and other factorswhich have a bearing on their intended use. Selection of these devices for listed pre-engineeredextinguishing systems should be based on their anticipated use with components of the listed fireextinguishing system. An important factor in proper selection of detectors is whether the fire-extinguishingsystem is actuated mechanically, pneumatically, or electronically.

A.4.2.5 Detector control panels are cabinets that often house microprocessors, electrical terminals,batteries, light emitting diodes, relays, fuses, and other electronic equipment. Detector control panels areused to interpret the output signals from detectors and cause releasing circuits to actuate thefire-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.

Public Comment No. 10-NFPA 17A-2015 [ New Section after 4.4.4.1 ]

Add the following language as 4.4.4.1 and renumber accordingly

4.4.4.1 On actuation of any cooking equipment fire extinguishing system, all sources of fuel and electricpower that produce heat to all equipment protected by the system shall be shut down.


4.4.4.1 was removed as a result of the first draft. Substantiation of first draft change was based on intent to improve correlation between NFPA 17A and 96.

Although this is certainly the direction committees are taking, it is the belief of the Fire Suppression Systems Association and its’ membership that this does not improve nor clarify the intent of the standard, which by NFPA definition is:

1.2 Purpose. 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.

Removal of this paragraph will diminish the guidance this standard is intended to provide. Having it in both 17A and 96 provides additional opportunities for the requirements to be followed.

(3) Recertification shall include a confirmation that all appliances originally filed and approved have notchanged location, size, manufacturer or type and that all appliances, hood,duct and plenumn are fullyprotected meeting the original installation requirements . If a manufacturers has updated or made aaddendun for a nozzles coverage, this change shall be provided to the AHJ and industry; the mostcurrent nozzle coverage shall apply.

(4) All detection, activation and manual mechanical system shall be visually examined to assure that novisable signs of grease, debris, dust willl impair the operation of the system.A full funtional test of thesystem shall be performed.

(5) All mechanical and electrical detection, fuel and appliance shutdown and releasing systems shall befully tested in compliance with original installation procedures

(6) A nitrogen or air test shall only be performed on an original installation or after a systemsextinguishing 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.
