Branch circuit emergency lighting control transfer switch by hubbell control solutions the ul1008bcelts1277 is specifically listed for branch circuit emergency lighting control under the new ul standards. A custom ul924 relay control system was requested by the specifier to replace a central dc battery system.

With this method of emergency lighting selected branch circuits can be automatically switched from normal power to emergency power upon loss of normal power by a transfer switch that is electrically operated and mechanically held in accordance with 700 5. The lighting load can be switched on off using an individual wall switch. In automatic load control applications when normal power is present the esr relay coil is activated and the emergency panel is fed from normal power. The lighting on the emergency circuit is switched on and off based on the normal circuit switching input to the unit.

This unit is intended for applications where both a normal and emergency branch circuit are to be connected to the emergency lighting. The nlight npp16 er series relay pack is used to switch luminaires powered via an emergency circuit. When normal power drops out the esr coil is deactivated and n c contact falls closed. Our enclosed 20 amp electrically held ul 924 automatic load control relay is specifically designed for projects requiring control of an emergency lighting along with controlled general lighting in a space.

These devices sense normal power and automatically connect the emergency power source to its lighting loads during a power outage. Emergency lighting transfer switches enable general illumination lighting fixtures to act as emergency lighting fixtures when an emergency power source is available.
