5 Emergency Lighting System
This is an example of how the Redwood Universal Gateway — Outage Relay can be used in conjunction
with a dry contact relay to communicate the system health of a Redwood Engine.
The following diagram illustrates how an emergency light can be switched on in the event of or an Engine
failure or during a loss of normal power to the Engine or to the circuit that supplies power to the
emergency lights.
The dry contact relay is used to signal the status of the Engine. A closed relay signifies a powered up and
properly functioning Engine, while an open relay signifies loss of power or some other problem with the
Engine.
