Zusammenfassung: | An emergency lighting system comprising an electrical panel board comprising a two-pole switched breaker with one pole controlled using an Emergency Remote Operated Relay. Each of the poles of the circuit breaker is fed by a single phase. The controlled pole feeds normal power to the lighting ballast operating under normal conditions. The non-controlled pole feeds constant power to at least one battery which provides back-up power to the light(s) in an emergency/power failed condition. The Emergency Remote Operated Relay further comprises a two pole circuit breaker (BQD 2P) with one of the poles connected to a Remote Operated Relay that is remotely controllable. |
