NAC477.365. Fire alarm systems: Evidence of capability to provide service; agreement for maintenance; notification of discontinuance of service; plans and specifications; level of sound.

     1. The distributor or installer of a fire alarm system must submit evidence of his or her capability to provide for any needed repair and restoration of the system within 24 hours after being notified of a fire or fault in the system. The evidence of that capability is subject to approval by the State Fire Marshal and must include a showing that the distributor or installer has:

     (a) The necessary equipment and qualified personnel to perform the service;

     (b) Provided a letter to the State Fire Marshal stating that the distributor or installer is capable of responding to and initiating repairs of a fire alarm system within 24 hours after being notified that the system requires service; and

     (c) A valid license issued by the State Contractors’ Board.

     2. Where fire alarm systems are installed, a satisfactory agreement for the maintenance of the system must be provided. A licensed company shall give a 30-day notice to the owner, the occupant and the authority having jurisdiction before the company may discontinue service to the owner and the occupant. All systems must be under the supervision of qualified persons. These persons shall have proper tests and inspections made at prescribed intervals and have general charge of all alterations and additions to the systems under their supervision. A copy of the maintenance agreement, along with proof that the firm or company which will provide the maintenance is adequately covered by liability insurance, must be submitted by the firm or company to the local fire department having jurisdiction and the State Fire Marshal.

     3. Detailed plans of alarm systems must be submitted to the authority having jurisdiction. The specifications must state that the installation will conform to applicable standards and meet the approval of the authority having jurisdiction. The specifications must include the specific tests which may be required to meet the approval of the authority having jurisdiction. Plans must be drawn to an indicated scale or be suitably dimensioned and must be made so that they can be easily reproduced. Plans must contain sufficient detail to enable the authority having jurisdiction to evaluate the effectiveness of the system. Plans must be submitted to and approved by the authority having jurisdiction before the system may be installed. Where field conditions necessitate any substantial change from the approved plan, the corrected plan showing the system as actually installed must be submitted to the authority having jurisdiction. Plans must be on the job site at all times when work is being performed pursuant to that plan at that site.

     4. All areas in a high-rise building protected by a fire alarm system and all areas protected by a fire alarm system must be provided with sufficient notification devices to achieve 80 decibels of sound at any occupied space within the area protected. All other occupancies must have an alarm system or systems which produce a sound that exceeds the prevailing equivalent sound level in the room or space by 15 decibels, or exceeds any maximum sound level with a duration of at least 30 seconds by at least 5 decibels, whichever is louder. The level of sound for the alarm signal must not exceed 120 decibels.
