Designed to bypass control of the emergency lights with a power loss.
Forces designated emergency lights ON.
Mounts in a junction box, lighting panel, or in a fixture
Meets UL 924 requirements.
This Emergency Transfer Control is designed for an application where designated emergency
lights and normal lights are ON/OFF controlled by a lighting control panel during non-emergency times. When a power outage occurs, the UL 1008 Transfer Switch transfers power from
the Normal power to the Emergency power source. At the same time the EPC-A unit senses
the outage and overrides the emergency power ON to the dedicated emergency lights.
The normal lights will be OFF during the outage and will resume the state they were in when
normal power is restored. A 10-15 second emergency load off delay is provided as an
automatic diagnostic test. LED status indicators for normal and emergency power are built in.
