Page Count: 142
scope:

These requirements cover electrical control units and accessories for fire-protective signaling systems to be employed in ordinary indoor locations in accordance with the following Standards of the National Fire Protective Association:

NFPA 12 Carbon Dioxide Extinguishing Systems

NFPA 12A Halogenated Extinguishing Agent Systems, Halon 1301

NFPA 12B Halogenated Extinguishing Agent Systems, Halon 1211

NFPA 70 National Electrical Code

NFPA 72 Installation, Maintenance, and Use of Protective Signaling Systems

A control unit as covered by these requirements consists of a unit assembly of electrical parts having provision for the connection of power supply circuits routed through the control unit equipment by a prescribed scheme of circuiting. The circuits are extended to separate devices by which the operating part of the control unit are actuated for signals, and to separate and/or integral devices by which the signals are indicated so as to form a coordinated system combination for definite signaling services. An installation wiring diagram attached to the control unit, or referenced in the control unit marking, indicates the devices and circuits which are acceptable for connection to the control unit in the field.

These requirements do not cover manual boxes, automatic fire detectors, automatic transmitters, or other initiating devices; nor do they cover bells, registers, or other indicating devices not provided as part of the control unit.
