1 Scope
1.1 These requirements cover the construction and security of equipment intended to automaticallydispense currency when operated as intended by an authorized customer, and to provide a limited degreeof protection against unauthorized removal of currency.
1.2 lf the product also receives deposits, the same degree of protection shall also be provided for thedeposits.
1.3 Records shall be made in order that the authorized customer may be debited for the currencydispensed.A limited degree of protection against unauthorized manipulation or removal of the records thatwill prevent proper debit shall be provided.
1.4 A teller’s cash dispenser is not required to make records.
1.5 These requirements cover products intended for permanent connection to 600-volts or lower-potentialbranch circuits,and products intended for cord connection to 300-volt or lower-potential branch circuits.The branch circuits and the means of supplying the units from them are intended to comply with theNational Electrical Code,ANSI/NFPA 70.
2 General
2.1 Components
2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply withthe requirements for that component. See Appendix A for a list of standards covering components usedin the products covered by this standard.
2.1.2 A component is not required to comply with a specific requirement that:
a) lnvolves a feature or characteristic not required in the application of the component in theproduct covered by this standard, or
b) ls superseded by a requirement in this standard.
2.1.3 A component shall be used in accordance with its rating established for the intended conditions ofuse.
2.1.4 Specific components are incomplete in construction features or restricted in performancecapabilities. Such components are intended for use only under limited conditions,such as certaintemperatures not exceeding specified limits,and shall be used only under those specific conditions.
2.2 Units of measurement
2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.
2.2.2 Unless otherwise indicated, all voltage and current values mentioned in this standard areroot-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 shallbe interpreted as referring to the latest edition of that code or standard.
2.4Terminology
2.4.1 The term “product”as used in this standard refers to any equipment covered by this standard.3 Glossary
3.1 For the purpose of this standard, the following definitions apply.
3.2 AUTHORIZED CUSTOMER – A person authorized to conduct transactions at an automated tellersystem.
3.3 AUTOMATED TELLER MACHINE (ATM)- An unattended machine that will dispense currencywhen operated as intended by an authorized customer and which will provide a limited degree ofprotection against unauthorized removal of currency.The product may also receive deposits.
3.4 BUSINESS HOUR SERVICE – A product that is available during business hours only, is underobservation by responsible persons,and is emptied of all valuables at the close of business.
3.5 CIRCUITS,ELECTRICAL –
a)HIGH-VOLTAGE – A circuit involving a potential of not more than 600 volts and havingcircuit characteristics in excess of those of a low-voltage, power-limited circuit;
b)LOw-VOLTAGE (POWER-LIMITED)- A circuit involving a potential of not more than 30volts alternating current (AC) rms, 42.4 volts direct current (DC) or AC peak, and providing notmore than 100 volt-amperes (VA) rated output.The 100 VA limit shall be provided by the
design of the transformer, a fixed impedance, a non-interchangeable fuse, a nonadjustablemanual reset circuit protective device, or a reliable regulating network;
