2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.4 Terminology 2.4.1 The term ″product″ as used in this standard refers to all types of antitheft alarms and devices. 3 Glossary 3.1 For the purpose of this standard the following definitions apply. 3.2 CIRCUITS, ELECTRICAL – a) High-Voltage (Class 1 ) – A circuit involving a potential of not more than 600 volts and having circuit characteristics in excess of those of a low-voltage power-limited circuit. b) Low-Voltage – A circuit involving a potential of not more than 30 volts alternating current (AC) rms, [42.4 volts peak or direct current (DC)].
5 General 5.1 Product assembly 5.1 .1 The product shall be factory-built as a complete assembly and shall include all the components necessary for its intended function when installed (used) as intended. The product may be shipped from the factory as two or more major subassemblies. See 5.1 .2. 5.1 .2 A product that is not assembled by the manufacturer as a complete unit shall be arranged in major subassemblies. Each subassembly shall be capable of being incorporated into a complete assembly without requiring alteration, cutting, drilling, threading, welding, or similar tasks by the installer (user). Two or more subassemblies, which must bear a definite relationship to each other for the intended installation or operation of the product, shall be arranged and constructed to permit them to be incorporated into the complete assembly only in the correct relationship with each other without need for alteration or alignment, or such subassemblies shall be assembled, tested, and shipped from the factory as one element. 5.2 Electrical protection 5.2.1 Louvers and other openings in the enclosure shall be constructed and located to reduce the risk of unintentional contact with uninsulated high-voltage live parts. In determining compliance with this requirement parts, such as covers, panels, and grilles, used as part of the enclosure are to be removed unless tools are required for their removal or an interlock is provided. See also Protection of Service Personnel, Section 6. 5.2.2 Uninsulated high-voltage live parts shall be located, guarded or enclosed as indicated in 5.2.3 – 5.2.5.
