Leviton White Emergency Dimming Power Load Center Relay 120-277V (ECS00-DDW)

In the past, emergency lights were kept on 24 hours a day to meet life safety codes. More precise and energy saving control is now possible with the Emergency Power Control (ECS00), which converts normal light fixtures into approved emergency lights. ECS00 saves energy and money while ensuring compliance with both life safety and energy codes. During normal operation, the same dimmer, occupancy sensor, dimming panel, or lighting control can switch and dim normal and emergency fixtures on and off simultaneously. During a utility power interruption, the ECS00 automatically bypasses the normal lighting controls, turning the emergency lights ON at full brightness, regardless of the dimmer position. The ECS00 is ceiling or wall mounted in a junction box with a single-gang plaster ring, usually located in the area where the emergency fixtures are installed.
