functions performed by the fire alarm system as an output of the fire alarm system, controlled by a relay or similar device, for example, elevator recall, fan shut down and door release
bonding
a low impedance path obtained by permanently joining all non-current-carrying metal parts to assure electrical continuity and having the capacity to conduct safely any current likely to be imposed on it
cathodic protection
technique to control the corrosion of a metal surface by making that surface the cathode of an electrochemical cell
extra-low voltage
any voltage up to and including 30 V AC or 42.4 V DC as per CEC
grounding
a permanent and continuous conductive path to the earth with sufficient ampacity to carry any fault current liable to be imposed on it, and of a sufficiently low impedance to limit the voltage rise above ground and to facilitate the operation of the protective devices in the circuit
high-voltage system
any voltage exceeding 1 000 V AC or 1 060 V DC as per CEC
low-energy power circuit
a circuit where the power is limited to 100 VA where V is the open circuit voltage
low-voltage system
any voltage exceeding 30 V AC but not exceeding 1 000 V AC or exceeding 42.4 V DC but not exceeding 1 060 V DC as per the CEC
luminaire
a complete lighting unit designed to accommodate the lamp(s) and to connect the lamp(s) to circuit conductors, for example, florescent, High Intensity Discharge (HID) and incandescent
raceway
any channel designed for holding wires, cables or busbars, and, unless otherwise qualified by rules of the CEC, the term includes conduit (rigid, flexible, metal, non-metallic) electrical metallic and non-metallic tubing, underfloor raceway, cellular floors, surface raceways, wireways, cable trays, busways, and auxiliary gutters
specifications
an explicit set of requirements to be satisfied by a material, product or service including but not limited to local and national building codes, any documentation that holds legal obligations, schematics, manufacturers’ specifications, local code, provincial/federal authority, engineered drawings and diagrams and schematics, client requirements, warranty documents, site drawings, shop drawings, company requirements
