The high rate fire extinguishing bottle is automatically armed,
Plus
a firebell aural sounds,

the associated cargo compartment extinguishing button illuminates,
the EICAS warning and advisory messages are displayed
To extinguish a fire in the forward cargo compartment, pilots must _______.
Select the illuminated cargo fire extinguisher button
In flight, the low rate fire bottle will discharge automatically after one minute,
providing protection from re-ignition for _______ minutes.
75 min.
True or False: On the ground, the cargo compartment low-rate extinguisher fire bottle will automatically discharge.
False
(On the ground, it won’t automatically discharge)
True or False: The cargo fire extinguishing system CANNOT be used in the
absence of an alarm condition.
False
In the event that there is an absence of a fire alarm condition, which of the
following is true about the forward and aft cargo compartments?

True or False: The forward and aft lavatories do not have any fire protection
Installed.
False
True or False: The fire extinguishers that are installed in each lavatory will only
extinguish a fire located in the lavatory waste bin.
True
True or False: The lavatory fire extinguishing system has flight deck controls.
False
At what temperature will the lavatory fire extinguisher automatically discharge?
172 degrees Fahrenheit
Lavatory fire extinguishing is accomplished how?
(When the temperature inside the waste bin exceeds 172 degrees Fahrenheit)
Automatically by the melting of a squib in the extinguisher discharge nozzle

True
Which of the following statements best describes the operation of the cargo fire extinguisher system?
After the annunciation of smoke detection in the cargo compartment, pressing the associated cargo compartment button causes:
