[SML] house light control systems recommendations needed

In our situation, the emergency system is activated outside of the dimming/control system.  

Select house and stage lights are on a relay.  1 side of the relay is the dimmer supply, and the other side is the emergency system (land line and then genny).  

If the Relay control circuit loses power, the relays throw to the emergency power supply, and lit up the room.
If the fire alarm is activated, the system triggers the relay and the system lights up.

So there is no need for human interaction to turn on the lights in an emergency.

If there is a need to evacuate without triggering the emergency system (bomb), then the console operator would turn on house and work lights.
