what is important thing need to do after push back the fire handle back to normal?
we need to reset the IDG generator field by toggle the switch at the P461 panel. if didnt reset, the IDG will not provide power after pull and push back the fire handle.

add on - if it didn't work reset at P5, generator field control switch.
know the system affected when fire handle is pulled:
1. Hydraulic motor shut off valve closed
2. Fuel spar valve closed
3. PRSOV closed
4. Cut off generator field exciter
5. Arm fire extingushing system, squib and bottle
6. Pack trip, recirc fan off
correction on alvin's comment number 6. pack wont trip and recirc fan wont off.
unless u arm the cargo fire arm switch
correction:
1. Hydraulic motor shut off valve closed
2. Fuel spar valve and engine fuel control valve closed**
3. PRSOV closed
4. Cut off generator field exciter
5. Arm fire extingushing system, squib and bottle
6. silence fire bell**
