What operations/actions are required for smoke detected in the avionics compartment?

a. When smoke is detected immediate actions include setting the Vent Extract pb to OVRD with or without ECAM activation, however, after the ECAM is displayed the ECAM checklist must be followed even if non avionics smoke is suspected.
b. When air conditioning smoke is suspected the crew should set the Vent Extract pb to OVRD and may continue with the paper checklist or switch to the ECAM procedure when displayed.
c. The Vent Extract pb should be set to OVRD once Emergency Electrical Configuration has been established.
