A320 Eng Agent 2 on Battery

Hi, can someone please confirm from the maintenance manual circuit diagram about engine agent 2 availability on battery power. I cant understand why they have written "Engine Agent 2 is not available" as highlighted in the EMER EVAC procedure below:

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.
