(SIG-FUN) Submittal Date: Wed Sep 11 15:00:34 EDT 2013 Committee Statement: The definition is revised to better correlate with the new condition - signal - response concept and terminology. Response Message: Public Input No. 144-NFPA [Section No ]

2 First Revision No. 244-NFPA [ Section No ] * Impairment. An abnormal condition where a system, component, or function is out of order, and the condition can result in the system or unit not functioning when required., of either a planned or emergency event, where a system, component, or function is inoperable. (SIG-FUN) * Emergency Impairment. An abnormal condition where a system, component, or function is out of order due to an unexpected deficiency. (SIG-FUN) * Planned Impairment. An abnormal condition where a system, component, or function is out of service due to work that has been planned in advance. (SIG-FUN) Supplemental Information File Name Attachment_for_FR_244.EC_edits.docx Description Submittal Date: Fri Sep 20 14:09:32 EDT 2013 Committee Statement: The language emergency impairment and planned impairment appear in Chapter 3 of the Code, and nowhere else. This goes against the NFPA manual of style, so the definitions are being deleted. However to make it clear that an impairment can be either planned or not, language is being added to the definition of impairment in Examples of emergency impairment and planned impairment are being moved to the Annex to provide additional details on what an impairment can be. This FR also deletes A and A This FR also modified A see attached. Response Message: Public Input No. 149-NFPA [Section No ] 7 of /21/2013 1:03 PM

3 A Impairment. An impairment is a system component or function that is not working properly, which can result in the system or unit not functioning when required. This might be due to an intentional act, such as closing a valve or disabling an initiating device. The impairment also might be caused by a deficiency in a piece of equipment or subsystem. An example of emergency impairment is physical damage to a control unit or wiring. Examples of a planned impairment include the addition of new devices or appliances or the reprogramming of system software.

Supplemental Information File Name Attachment_for_FR_275.EC_edits _2_.docx Description Submittal Date: Tue Sep 24 07:42:02 EDT 2013 Committee Statement: Section (formerly ) is better suited to appear in the Documentation Chapter. Incorporated the requirement from into The use of electronic media is becoming more popular as time progresses. Electronic media today can be, thumb drives, CD ROM's, or floppy disc media. Some of this might be current today, the future does not support all media. Today's computers do not currently support floppy disc media. The stored media must be relevant to the system, today's computers, and programs. This FR also adds new A see attached.

23 A Documentation stored in electronic media can become obsolete, for example, 5.25 in. and 3.5 in. disks and tape drives are not supported by current technology. Updating the stored media to current technology concerns the programs used to operate them, and the computer or hardware used to interface to the system installed. Thus, it is necessary to ensure that all components are still compatible with the installed system.

Supplemental Information File Name Attachment_for_FR_257.EC_edits.docx Text_for_FR_257_main_body_.EC_edits.docx Description Submittal Date: Mon Sep 23 09:44:10 EDT 2013 Committee Statement: Response Message: The revised text has been updated for compliance with the manual of style and to improve usability. The value of 20% margin is specified as a minimum. This FR also adds A see attached. The added annex material is provided to explain how the safety margin could be larger depending on battery loading. 14 of /21/2013 1:03 PM

56 A The 20-percent minimum reserved capacity is intended to address both normal aging and effects of battery loading. Some systems with a high rate of alarm signaling battery discharge might require a greater safety margin. Battery calculations should take into account a discharge factor resulting from the discharge of batteries at a greater rate than the one specified in the battery data provided by the manufacturer. For example, valve-regulated lead-acid (VRLA) batteries are typically assigned a 20-hour discharge rate (C/20). Any rate greater than C/20 requires using the manufacturer's formula or discharge factor table.

57 * Capacity The secondary power supply shall have sufficient capacity to operate the system under quiescent load (system operating in a nonalarm condition) for a minimum of 24 hours and, at the end of that period, shall be capable of operating all alarm notification appliances used for evacuation or to direct aid to the location of an emergency for 5 minutes, unless otherwise permitted or required by the following: through (1) * Battery calculations shall include a minimum 20 percent safety margin to above the calculated amp-hour rating capacity required.

69 82 of /21/2013 1:03 PM First Revision No. 195-NFPA [ New Section after A.7.2 ] A In many cases, the installer might not have adequate record drawings or other completion documentation for the existing system. As an example, where a temporary school building is being installed, the fire alarm system subpanel in the temporary building should be fully documented, but the fire alarm system for the entire existing school might be so old that adequate documentation might not exist. In this example, documentation required in Section 7.2 should be completed only for the new subpanel and the interfaces to the existing school fire alarm system. Submittal Date: Fri Sep 13 11:40:11 EDT 2013 Committee Statement: There are many instances where the minimum documentation required in Section 7.2 is not available for the existing system which is being altered or added to. This section helps clarify that, with the permission of the AHJ, the requirements of Section 7.2 to apply only to the modifications or additions, as well as the interfaces to the existing older fire alarm system.

71 85 of /21/2013 1:03 PM First Revision No. 171-NFPA [ New Section after A ] A The purpose of this requirement is to ensure that circuit disconnecting means for fire alarm and signaling systems are readily identifiable so that users will not mistakenly disconnect the power to the system or so that they can quickly disconnect power without having to search the electrical panelboard chart to identify the circuit. The intent of this requirement is not to require specific text for marking. It would be acceptable to show the text using upper and/or lower case, such as fire alarm, or Fire Alarm, or FIRE ALARM. Submittal Date: Wed Sep 11 18:21:52 EDT 2013 Committee Statement: Response Message: The new annex material is intended to clarify the purpose for the marking and that there are multiple ways to provide the text.
