The EPC-D-F-S is the most powerful UL924 device available in terms of functionality and reliability. The EPC-D-F-S can be used with any dimming system (line voltage, 0-10V, 3-wire, DALI, and more) and ensures that during a power interruption emergency lights will illuminate at full brightness. A triple safety design including time delay, mechanical, and electrical interlocks prevents inadvertent cross-connection, even in the event of device failure. The attractive surface mounted package allows the device to be installed in an electrical room or on a junction box. Also available in a flush mounted package (see EPC-D-F).
