Description
Features:
- Soft Start Control with user-selectable 0 to 2 second voltage ramp to accommodate the high inrush current associated with energizing certain types of lighting fixtures.
- User-Adjustable Transfer Delay to and from emergency power to best fit specific applications.
- Remote Command Transfer (RCT) allows external contact(s) to initiate the automatic transfer of all circuits from normal to emergency power during critical NFPA-mandated test periods.
- The RCT input may connect to a Controlled Power Company emergency lighting inverter’s “test active” contact to initiate the transfer of emergency circuits.
- As the Controlled Power lighting inverter automatically performs and logs NFPA-mandated tests, all emergency lighting loads are energized to validate system testing.
- A local keyed test switch is provided to simulate a power failure during manual testing of the emergency lighting and life safety system.
