 -confirms the closure of the LP fuel shut off valve
 -de-energizes the IDG
 -closes the hydraulic shuts off valve
 -lights on the SQUIB legends associated to two fire extinguisher bottles (AGENT 1 and 2)
 -stops the Aural Warning: the Continuous Repetitive Chime (CRC)

 8. BITE Test_________
 A. Operational Test
 (Ref. Fig. 006)

 The operational test enables the pilot to monitor and activate the fire protection system. This test is part of the daily check-list and is available each time it is needed, on the ground or in flight.
 You can do the operational test of the fire extinguishing system by pushing the TEST pushbutton switch (one per engine) located on the ENG/APU FIRE panel.
 NOTE : The TEST pushbutton switch must be held during the whole test
____ duration. The response time of the test is lower than 1 second.
 The ENG/APU FIRE panel (1WD) provides the test logics and ensures the electrical continuity of:
 -
the firing circuitry of the fire extinguisher bottle

 -
the low pressure warning circuitry of the fire extinguisher bottle.
