(1) On the CAPT jack panel, connect the HEADSET 600 OHMS to the related
connector.
(2) On the overhead panel 285VU, make sure that the ON legend on the SVCE INT
OVRD pushbutton switch 15RJ is off.
(3) In Zone 132, connect the BOOMSET 600 OHMS to the service interphone jack.
(4) At the fire extinguisher bottles:
(a) Do the procedure for electrostatic discharge sensitive-devices:

WARNING:
DO NOT TOUCH THE CARTRIDGE BEFORE YOU DO
THE PROCEDURE APPLICABLE TO DEVICES THAT
ARE SENSITIVE TO ELECTROSTATIC DISCHARGE.
ELECTROSTATIC DISCHARGE CAN CAUSE THE FIRE
EXTINGUISHER BOTTLE TO RELEASE ITS CONTENT
SUDDENLY AND CAUSE INJURY TO PERSONS.

1 Before you touch the cartridges, do the procedure for devices that are
sensitive to electrostatic discharge (Ref. AMM TASK 20-15-00-912-
801) .
(b) At the cartridges of the fire extinguisher bottles:

WARNING:
BEFORE YOU TOUCH THE POWER DEVICE CARTRIDGE,
MAKE SURE THAT YOU ARE GROUNDED AND THAT YOU
INSTALL A SHUNT DEVICE ON IT. USE A CAP OR PLUG
AS SHUNT DEVICE (THE CAP OR PLUG WILL SHUNT THE
PINS TOGETHER ON THE CARTRIDGE). DO NOT USE A FOIL
SHUNT.
IF YOU TOUCH A POWER DEVICE CARTRIDGE THAT DOES
NOT HAVE A SHUNT DEVICE INSTALLED, AN EXPLOSION
CAN OCCUR AND CAUSE INJURIES TO YOU.

1 Disconnect the electrical connectors from the cartridges:

· The electrical connector 4001WX-C from the cartridge 4001WX
· The electrical connector 4003WX-C from the cartridge 4003WX
· The electrical connector 4011WX-C from the cartridge 4011WX
· The electrical connector 4013WX-C from the cartridge 4013WX.
2 Put the CAP,PROTECTIVE-FIRE EXTINGUISHER SYSTEM (324477)

WARNING:MAKE SURE THAT YOU ARE GROUNDED AND THAT THE SHUNT
DEVICE IS INSTALLED ON THE ELECTRICAL CONNECTOR OF THE
CARTRIDGE. DO NOT USE A FOIL SHUNT. IF THE SHUNT DEVICE IS
NOT INSTALLED, THERE IS A RISK OF AN ACCIDENTAL EXPLOSION
OF THE CARTRIDGE. THIS CAN CAUSE INJURY TO PERSONS.

WARNING:MAKE SURE THAT ALL THE ELECTRICAL CONNECTORS

ARE DISCONNECTED FROM THE CARTRIDGES OF THE FIRE
EXTINGUISHER BOTTLES BEFORE YOU DO THIS TEST.
IF AN ELECTRICAL CONNECTOR IS CONNECTED, AN ACCIDENTAL
EXPLOSION OF THE CARTRIDGE WILL OCCUR. THIS CAN CAUSE
INJURY TO PERSONS.

(1) Wait 3 minutes to make sure that the system is correctly booted.
