Shop Drawings Shop drawings are required to include specific information, which is spelled out in chapter 7. Here’s a summary: Installer or contractor name Name of the owner and property information Protected premises location Device legend and symbols Issue and revision dates

The floor plans are to include the following information: Floor or level identification Compass reference Graphic scale Specific information regarding riser locations, space designations, devices, circuits, excessive ceiling heights, and ceiling geometry

The floor plans are to include the following information: Riser diagrams noting the system arrangement in building cross section, type and number of circuits, type and number of components on each floor, and number of conductors

The floor plans are to include the following information: Control unit diagrams noting the location of the equipment, fire alarm primary power disconnecting means, field wiring terminals and terminal identification, as well as circuits connected to field wiring terminals and circuit identification Typical wiring diagrams for all devices Narrative description or an input/output matrix and sequence of operation System calculations (battery, voltage drop, and other required calculations).

Record Drawings Record drawings consisting of current updated shop drawings reflecting the actual installation of all system equipment, components, and wiring also must be prepared. In NFPA 72-2010, there was a single system record of completion for the fire alarm system and supplementary forms for other systems. These supplementary forms also address documenting the power systems, notification appliance power panels, interfaced equipment, and mass notification systems.

Fundamentals Reorganized for the 2013 edition to provide a more user-friendly flow of requirements.   Extensive usability changes have also been made in the support chapter, "Inspection, Testing and Maintenance.”  These changes occur primarily within the inspection and testing tables.   The visual inspection table has been updated, adding new inspection methods for each component along with the inspection frequency.   The test methods and test frequency tables have been combined into a single table so that the test method appears along with the test frequency for each component.   The component listings in both tables have been reorganized and coordinated so that components and equipment are easier to find.

Fundamentals cont. Require supervising station operators and fire alarm system service providers, respectively, to report to the authority having jurisdiction when monitoring service has been terminated or when a system has been out of service for more than eight hours. Also within this chapter, requirements for inspection, testing, and service personnel qualifications have been updated to better reflect the level of qualification needed for each type of activity.   This includes a new provision requiring system programmers to be certified by the system manufacturer.

Circuits and Pathways Updated to incorporate specific circuit performance and integrity information, Revised and relocated from the chapter on protected premises fire alarm systems. Also, a new section has been added to address prioritization and segregation of life safety and non-life safety data in shared pathways.

Inspection, Testing and Maintenance Modifications have been made throughout the support chapter to clarify that the requirements apply only to the systems, devices, and components covered by the code – not to components of other systems. In addition, inspection methods have been added to the inspection table along with the inspection frequencies.  Also, new provisions have been added to require that a test plan be written to establish the scope of testing for fire alarm systems.

The support chapter "Initiating Devices” Updated to clarify requirements for accessibility and labeling of remote alarm and supervisory indicators.  In addition, the provisions in this chapter that address total coverage detection have been revised and coordinated to clarify the approach to be taken when return air plenums are involved.  Also, the provisions addressing spot-type smoke detector spacing in high- airflow conditions have been revised to clarify that adjustments for high airflow must be made prior to any adjustments for ceiling construction.

Notification Appliances Coverage for occupant notification (generally specified by other governing laws, codes or standards) only applies in occupiable spaces, as defined in NFPA 72.  In addition, the provisions in this chapter for audible signaling have been updated to require documentation of the locations that require (and do not require) audible notification as well as documentation of the audibility levels that must be produced. Similar area-of-coverage documentation requirements were also added for visible notification.  

Notification Appliances Also, provisions for the use of the standard alarm evacuation signal (the three-pulse temporal code) have been updated to extend to signals used for relocation and partial evacuation, not just complete evacuation.  Finally, provisions addressing textual and graphical visible appliances have relocated from the chapter on emergency communications systems to this chapter and have been expanded to include fire applications and refined to include location, mounting and performance requirements.

Emergency Control Function Interfaces” Specifically address requirements for elevator recall when sprinklers are installed in elevator pits. The requirements for occupant evacuation elevators have also been completely revised to coordinate with changes being made in ASME A.17.1/B44, Safety Code for Elevators and Escalators. In addition, requirements for fire alarm systems interfacing with HVAC systems have been updated, as have the requirements for door and shutter release and requirements for electrically locked doors.

Protected Premises Fire Alarm Systems Updates to address the monitoring of carbon monoxide detection systems by fire alarm systems.   Carbon monoxide detector activations are required to be displayed on the fire alarm system as "carbon monoxide alarm” signals. Also, provisions have been added requiring that if a valve is installed in the connection between a sprinkler system or a suppression system and an initiating device, the valve must be supervised.

Chapter 10: Fundamentals Reorganized Much of the material in chapter 10 has been reorganized. The requirement for protection of control equipment has been inserted in section 10.4.4, which requires smoke detection to be provided at the location of each fire alarm control unit, notification appliance circuit power extender, and supervising station transmitter unless the equipment is in a constantly occupied area. The requirements for qualifications of inspection and testing personnel have been moved from chapter 14 into chapter 10 as well. The qualification requirements for all personnel have been expanded to also be applicable to personnel working with emergency communication systems.

A reference has been added in section 10.6.7.2.1(8) regarding capacity of power supplies for two-way radio communications enhancement systems. This section refers you to section 24.5.2.5.5, which has new requirements for the power supplies for two-way radio communications enhancement systems. These requirements include two sources of power and require either 12 hours of capacity in storage batteries or 12 hours of capacity provided by an automatic starting engine driven generator plus 2 hours of battery capacity. New paragraphs 10.7.5 and 10.7.6 allow carbon monoxide signals and pre- alarm signals to take precedence over supervisory and trouble signals.

New sections 10.8 and 10.9 Clarify the perceived confusion regarding different types of signals and the system response to those signals. Section 10.8 Detection and Signaling of Conditions and 10.9 Responses address alarm, pre-alarm, supervisory, and trouble signals and responses to those signals.

A new paragraph 10.10.3 Requires audible alarm notification appliances for a carbon monoxide alarm system to produce signals that are distinctive from other signals from devices that may be serving the same area but are not part of the carbon monoxide, fire alarm, or emergency communication system.

A number of changes have been made in the system chapter "Emergency Communications Systems” including the following: The addition of specific references to documentation requirements in the new documentation chapter; The addition of a requirements to post instructions for the use of microphones in making voice announcements and for test messages to specifically state "this is a test;” The addition of ANSI/UL 2572,2 Standard for Mass Notification Systems, in the requirement for the listing of mass notification systems control units; The addition of a requirement to provide message templates for each message developed for scenarios of the emergency response plan;

A number of changes have been made in the system chapter "Emergency Communications Systems” including the following: Clarification of requirements for the use of live voice instructions in emergency voice/alarm communication systems upon release of the microphone; Updated in-building mass notification system documentation requirements to provide the owner with a written sequence of operations and a copy of the site- specific software; Updated requirements for voice message priority in in-building mass notification systems; Added provisions on the use of textual and graphical visible notification appliances for primary or supplemental notification; and, Updated requirements for the location and accessibility of emergency command centers.

"Supervising Station Alarm Systems” Addressing alarm signal verification, alarm signal content, and restoration of signals. These changes have been made in part to help emergency responders better manage issues related to unwanted alarms. In addition, new definitions for "unwanted alarms" have been added to more precisely identify the sources of these alarms.

"Supervising Station Alarm Systems” Cont. Changes have also been made to update the communications methods addressed in this chapter, including the following: Updated requirements for supervision intervals for both single and multiple communications paths; Changes to the types of transmission means that can be used for the second channel of a digital alarm communicator transmitter (DACT);

"Supervising Station Alarm Systems” Added provisions for signal processing equipment at supervising stations; Updated requirements for secondary power for shared communications equipment used with performance-based technologies; Added annex material to provide examples of technologies that fall under the requirements for performance-based technologies; and, Removed requirements addressing digital alarm radio systems

Public Emergency Alarm Reporting Systems Updated to prohibit the use of unlicensed radio frequencies in wireless networks.  In addition, revisions have been made to clarify the wireless network capacity for the number of alarm boxes on a single radio frequency. A new requirement has also been added to require circuit survivability for wiring between an auxiliary alarm system and the auxiliary or master box.

Single- and Multiple-Station Alarms and Household Fire Alarm Systems Modified the performance requirements for the low frequency alarm signal; Updated the provisions for visible and tactile notification so they apply to those with moderately severe as well as profound hearing loss; Changed the secondary power capacity requirements for smoke and heat alarms to 7 days instead of 24 hours; Introduced two new separate provisions addressing smoke alarm and smoke detector resistance to common nuisance sources in general, and to common cooking nuisance sources when installed within 20 ft (6 m) of a fixed cooking appliance;

Single- and Multiple-Station Alarms and Household Fire Alarm Systems Added provisions to address the connection of sprinkler waterflow switches to multiple-station alarms; Added provisions to require two simultaneous or sequential operations to activate a keypad fire alarm signal; and, The provisions for testing of smoke alarms (in the testing chapter) have been revised to eliminate the requirement for sensitivity testing
