Controlled Power SwitchLITE Model EZT UL 1008 Transfer Switch for Emergency Lighting
The Controlled Power SwitchLITE Model EZT UL 1008 transfer switch for Emergency Lighting is a UL 1008 listed Automatic Transfer Switch for Emergency Lighting Applications. The SwitchLITE Model EZT allows dimmable lighting fixtures to function as essential emergency lighting. The Model EZT (Emergency Zone Transfer Cabinet) is designed to automatically transfer up to eight branch circuits to emergency power when normal power fails, and then return to normal power once it has been restored.
When switching to emergency power, lighting fixtures that are dimmed or are off are brought to full illumination to provide safe egress. The Model EZT accommodates 4, 6, or 8 individual 20-amp branch circuits, and is ideal for use in a Dimmer Rack Application. User-adjustable settings are provided to control the transfer delay time to and from emergency power. Unique to the Model EZT, an emergency power Soft Start Control (SSC) is provided to accommodate the high inrush current associated with energizing certain types of light fixtures.
Controlled Power SwitchLITE Model EZT 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.
