LVS Emergency Power Controls (EPC's) save energy and money while ensuring compliance with life safety and energy codes. During normal operation, emergency fixtures can be switched or dimmed. During a utility power interruption, the EPC automatically bypasses the normal lighting controls, turning the emergency lights ON at full brightness, regardless of switch position. LVS offers the widest range of UL924 Listed Automatic Load Control, Bypass, Shunt, and Transfer Relays on the market. Our controls are used worldwide in commercial, industrial, and institutional applications.
