Public Input No. 351-NFPA 72-2013 [ Section No. 17.4.10 ] 17.4.10 * If the intent is to initiate action when smoke/fire threatens a specific object or space, the detector shall be permitted to be installed in close proximity to that object or space. Smoke detectors installed in concealed locations where the specific detector alarm or supervisory signal is indicated at the control unit (and on the drawings with its specific location and functions) shall not be required to be provided with remote alarm indicators as specified in 17.4.7. This new section takes the second condition in 17.4.9 from the previous edition of the code and makes it an exception to 17.4.7. It clarifies the intent of the section and reads better. Existing 17.4.10 and its associated annex section should be moved to new 17.4.11 and associated annex section. Submitter Full Name: Leonard Belliveau Organization: Hughes Associates, Inc.

Public Input No. 350-NFPA 72-2013 [ Section No. 17.4.9 ] 17.4.9 Where required by 17.4.7 and unless the specific detector alarm or supervisory signal is indicated at the control unit (and on the drawings with its specific location and functions), remote alarm or supervisory indicators shall be installed in an accessible location and shall be clearly labeled to indicate both their function and any device or equipment associated with each detector. The statement "and unless the specific detector alarm or supervisory signal is indicated at the control unit (and on the drawings with its specific location and functions)," in the code section is verbose and confusing. I suggest moving this section to a new section 17.4.10 as an "exception" and renumbering existing 17.4.10 to 17.4.11. Submitter Full Name: Leonard Belliveau Organization: Hughes Associates, Inc.

Public Input No. 70-NFPA 72-2013 [ Sections 17.7.1.11.1, 17.7.1.11.2 ] Sections 17.7.1.11.1, 17.7.1.11.2 17.7.1.11.1 Where detectors are installed for signal initiation during construction, they shall be cleaned and verified to be operating in accordance with the listed sensitivity, or they shall be replaced prior to the final commissioning acceptance test of the system. 17.7.1.11.2 Where detectors are installed but not operational during construction, they shall be protected from construction debris, dust, dirt, and damage in accordance with the manufacturer s recommendations and verified to be operating in accordance with the listed sensitivity, or they shall be replaced prior to the final commissioning acceptance test of the system. Additional Proposed Changes File Name Description Approved NFPA_72_4_Public-Inputs_2013_03_26.pdf Cover Sheet This Public Input (PI) seeks to amend and incorrect use of the word commissioning. The way the term is used in 17.7.1.11.1 and 17.7.1.11.2 of NFPA 72-2013 is to verify that an individual system component has been installed and operates in compliance with the code. Technically this is incorrect with respect to the definition of commissioning in NFPA 3. The term commissioning is defined as an owner-driven requirement to ensure that the building and its various systems are designed, installed, and operated in accordance with the owner s needs. Whereas an acceptance test is defined as functionally testing system components to verify that the individual system was installed and is operational in conformance with applicable standards and the AHJ.

Public Input No. 241-NFPA 72-2013 [ Section No. 17.7.3.2.4.1 ] 17.7.3.2.4.1 Solid joists and Open Bar Joists shall be considered equivalent to beams for smoke detector spacing guidelines. By adding Open Bar Joists, smoke detection could be spaced using the exceptions and detectors could be placed on the bottom of the beams for better access for maintenance and to keep the smoke detectors from being mounted directly to the ceiling corrugated panels, thus less heat during summer months on the detector itself. I think smoke detection would be just as quick as with solid beam detection I have done no testing on this subject.

Public Input No. 642-NFPA 72-2013 [ Section No. 17.7.5.6.5.3 ] 17.7.5.6.5.3 (A) If there are multiple doorways, additional ceiling-mounted detectors shall be required as specified in 17.7.5.6.5.3(A) through 17.7.5.6.5.3(C). If the separation between doorways exceeds 24 in. (610 mm), each doorway shall be treated separately. Figure 17.7.5.6.5.3(A), part E, shall apply. Figure 17.7.5.6.5.3(A) Detector Location Requirements for Single and Double Doors. (B) Each group of three or more doorway openings shall be treated separately. Figure 17.7.5.6.5.3(B) shall apply.

Each group of doorway openings that exceeds 20 ft (6.1 m) in width, measured at its overall extremes, shall be treated separately. Figure 17.7.5.6.5.3(C) shall apply. Figure 17.7.5.6.5.3(C) Detector Location Requirements for Group Doorways over 20 ft (6.1 m) in Width. Delete 17.7.5.6.5.3 and the figure entirely. Has anyone ever asked why the smoke detector has to be on the center line of the door opening? (Rhetorical question.) Yes, members of NFPA 101 and 105 wonder why there is no allowance for being offset even just wee bit. By doing away with this section, the requirements revert to the normal spacing and location requirements for smoke detectors as modified by the remaining parts of 17.7.5.6. While having the detectors closer to the center of the openings will likely improve response, this gets into factors of design that go beyond the requirements of a minimum code.

Public Input No. 353-NFPA 72-2013 [ Section No. A.17.4.10 ] A.17.4. 10 11 There are some applications that do not require full area protection, but do require detection, to initiate action when specific objects or spaces are threatened by smoke or fire, such as at elevator landings that have ceilings in excess of 15 ft (4.6 m) and for protection of fire alarm control units. In high-ceiling areas, to achieve the desired initiation, such as for elevator recall and protection of fire alarm control units (FACUs), detection should be placed on the wall above and within 60 in. (1.52 m) from the top of the elevator door(s) or FACU. Relocates Annex material to new A.17.4.11 if section 17.4.10 is relocated as suggested in Public Input 350, 351 and 352.

Public Input No. 574-NFPA 72-2013 [ Section No. A.17.4.10 ] A.17.4.10 There are some applications that do not require full area protection, but do require detection, to initiate action when specific objects or spaces are threatened by smoke or fire, such as at elevator landings that have ceilings in excess of 15 ft (4.6 m) and for protection of fire alarm control units. In high-ceiling areas, to achieve the desired initiation, such as for elevator recall and protection of fire alarm control units (FACUs), detection should be placed on the wall above and within 60 in. (1.52 m) from the top of the elevator door(s) or FACU. Smoke detection used to provide notification of a fire near a fire alarm control unit is required by 10.4.4. It might be advantageous to provide a smoke detector located on the wall above a control panel in situations with high ceilings. In this case, unlike an elevator recall smoke detector, the purpose for requiring this detection is to also provide notification prior to the operation of a sprinkler located on the ceiling over a control panel. If a fire occurs ceiling level in a light fixture, or on the top of a shelf or rack, it might not have any direct impact on a fire alarm control unit located well below the ceiling. However, that fire might activate a sprinkler that could cause water damage to the control unit before the waterflow switch has had time to respond, activate the control unit, activate occupant notification appliances and transmit a signal to an off premises supervising station. For these reasons, adding a smoke detector on the wall above the control panel should not be used as a reason to eliminate smoke detection at the ceiling. In high ceiling applications, adding a smoke detector in close proximity to the fire alarm control unit might provide earlier warning of a fire impacting the system compared to a detector located on the high ceiling. However, it is also necessary to detect a fire ceiling level if sprinklers are present even if fire at that location does not directly impact the control unit. In high ceiling applications, adding a smoke detector in close proximity to the fire alarm control unit might provide earlier warning of a fire impacting the system compared to a detector located on the high ceiling.

Features that should be investigated to minimize alarm response time include the following: (1) Elimination of trapped air in the sprinkler system piping (2) Use of an excess pressure pump (3) Use of pressure drop alarm-initiating devices (4) A combination thereof Care should be used when choosing waterflow alarm-initiating devices for hydraulically calculated looped systems and those systems using small orifice sprinklers. Such systems might incorporate a single point flow of significantly less than 10 gpm (40 L/min). In such cases, additional waterflow alarm-initiating devices or the use of pressure drop-type waterflow alarm-initiating devices might be necessary. Care should be used when choosing waterflow alarm-initiating devices for sprinkler systems that use on off sprinklers to ensure that an alarm is initiated in the event of a waterflow condition. On off sprinklers open at a predetermined temperature and close when the temperature reaches a predetermined lower temperature. With certain types of fires, waterflow might occur in a series of short bursts of a duration of 10 seconds to 30 seconds each. An alarm-initiating device with retard might not detect waterflow under these conditions. An excess pressure system or a system that operates on pressure drop should be considered to facilitate waterflow detection on sprinkler systems that use on off sprinklers. Excess pressure systems can be used with or without alarm valves. The following is a description of one type of excess pressure system with an alarm valve. An excess pressure system with an alarm valve consists of an excess pressure pump with pressure switches to control the operation of the pump. The inlet of the pump is connected to the supply side of the alarm valve, and the outlet is connected to the sprinkler system. The pump control pressure switch is of the differential type, maintaining the sprinkler system pressure above the main pressure by a constant amount. Another switch monitors low sprinkler system pressure to initiate a supervisory signal in the event of a failure of the pump or other malfunction. An additional pressure switch can be used to stop pump operation in the event of a deficiency in water supply. Another pressure switch is connected to the alarm outlet of the alarm valve to initiate a waterflow alarm signal when waterflow exists. This type of system also inherently prevents false alarms due to water surges. The sprinkler retard chamber should be eliminated to enhance the detection capability of the system for short duration flows.

72_Van_Keuren_2_Rev_1.pdf Cover Sheet The current wording of the code indicates that only the waterflow device ca do the delay of 90 seconds. With today's intelligent fire alarm systems the delay could be incorporated in the combination of the waterflow device and fire alarm system. This would be similar to alarm verification of smoke sensors.
