(e) Buildings fully protected by an automatic sprin- kler system installed in accordance with NFPA 13, Standard for the Installation ofSprinkler Systems, and with the interconnecting wiring or cables used for the operation ofnotification appliances installed in metal raceways and in accordance with Article 760 ofNFPA 70
5.2.3 Fire Alarm System Equipment remote from Fire Alarm Control Unit Where emergency voice/alarm control equipment is dependent on remotely located control equipment, install the interconnecting circuits using any ofthe following methods:.
(a) A 2-hour fire rated circuit integrity (CI) cable
(b) A 2-hour fire rated cable system (electrical cir- cuit protective system)
(c) A 2-hour fire rated enclosure
(d) Performance alternatives approved by the authority having jurisdiction
(e) Buildings fully protected by an automatic sprin- kler system installed in accordance with NFPA 13, Standard for the Installation ofSprinkler Systems, and with the interconnecting wiring or cables used for the operation ofnotification appliances installed in metal raceways and in accordance with Article 760 ofNFPA 70
5.3 Installation Guidelines Article 760 ofthe NEC contains the requirements for installation offire alarm system circuits: Non-powerlimited, and power-limited. These two types ofcir- cuits must be installed separate from each other. That is, do not install non-power-limited and powerlimited circuits in the same cable or raceway. Power circuit conductors are permitted to be installed in the same raceway with non-power-limited circuits, where the power circuit is functionally associated with the system—typically power for the control unit. Non- power-limited, power-limited, and control unit power circuits are permitted in a common enclosure.
5.3.1 General Requirements (NEC, Article 760, Part I)
a) Install all wiring to meet the requirements of Article 760 ofthe NEC, unless the NEC conflicts with local code. Local code prevails.
b) Identify fire alarm circuits at terminal and junction locations. An excellent practice is to install red covers labeled “Fire Alarm Circuit.”
c) Support cables by the building structure.
d) Install circuits extending beyond one building according to the requirements ofNEC Section 760.32, which refers to Article 225 and Article 800, Parts B, C, and D.
