A320 Engine Fire System Question
Hi

Can anyone shed any light on how Squib A and Squib B are controlled? When you press the BTL 1 button in the flight deck - does the system use squib A, squib B or both to discharge bottle 1? Can the flight deck influence which squib is used?

Basically, I am in the dark as to how the squibs fit into the engire fire protection system. Reference is made to squib A and squib B. Is there a squib A and B for bottle 1 AND a separate squib A and B for bottle 2?

Classic case of a picture speaking a 1000 words. I do not have access to any engineering diagrams which show the relationship of SQUIB A and SQUIB B to fire bottle 1 and fire bottle 2?

Thanks for any thougts.

Peter
