An emergency lighting system has emergency light units operable by DC power and connected to a source of AC and DC power by the same conduit system. Power to the conduit system may be switched from AC to DC in the event of a power failure and a load relay module in the conduit system adjacent the light units senses the change to DC current and switches from an Ac load output to a DC load output to supply DC power to the emergengy light units. The system will generally include both exit signs operable by both AC and DC power and emergency light units operable only by DC power.

Système d'éclairage de secours muni d'unités d'éclairage de secours pouvant fonctionner sous alimentation c.c. et reliées à une source d'alimentation c.a. et c.c. par les mêmes canalisations. On peut faire passer l'alimentation de ces canalisations de c.a. à c.c. en cas de panne de courant, et un module de relais de commande de ces canalisations contiguës aux unités d'éclairage, qui capte ce changement à une alimentation c.c., commute la sortie de charge c.a. en une sortie de charge c.c. pour fournir une alimentation c.c. aux unités d'éclairage de secours. Ce système comporte généralement des signaux de sortie pouvant fonctionner sous alimentation c.a. et c.c. et des unités d'éclairage de secours ne fonctionnant que sous alimentation c.c.
