a On the overhead CTL & IND panel 22VU:

Release the ENG/MAN START/1(2) pushbutton switch.

NOTE: A fire detected by the fire detection loops can be extinguished by portable or onboard fire-extinguishing systems.

(a) When there is an external engine fire, do this procedure:
1 Put the throttle control levers of the engines 1 and 2 in the idle stop position (zero on the graduated sector).
2 On the ENG panel 115VU:

Set the ENG/MASTER 1(2) switch to OFF.

3 On the ENG/APU FIRE panel 1WD, push the ENG 1(2) FIRE pushbutton switch:

The SQUIB legends of the applicable AGENT 1 and AGENT 2 pushbutton switches come on.
The audio warning stops.
