This standard (adopted as American national standard ANSI/UL 924 on 16 Oct. 1978) issues requirements for battery-powered emergency lighting and power equipment for use in ordinary indoor locations, in accordance with the National Electrical Code (CIS 78-31).

Definitions are followed by sections devoted to: construction (frame and enclosure; corrosion protection; current-carrying parts; wiring; earthing; batteries; electronic circuits; capacitators; overcurrent protection); exit lights; performance (leakage current, current input temperature, overvoltage and undervoltage, voltage surge, dielectric withstand); ratings; markings; instruction manual; low-frequency and high-frequency inverters. The supplement (revision pages) indicates changes from, and additions to, previous editions. |
