This is because ENG 1+2 Fire bottle 1 squibs A+B are supplied by the 28VDC HOT BUS (direct from batteries)

And ENG 1+2 Fire bottle 2 squibs A+B are supplied by the 28VDC BUS 2 (from TR2)

Is this setup only on this type (A320) or on all airbus types? Its been a long time that I flew A310, B737 and B777 but cannot recall anything like this.
