 D. Operation in Warning Configuration The alarm output (discrete signal) is activated when the alarm threshold is reached. As the smoke detector operates in autonomous mode, the corresponding warnings are directly triggered by means of relays to the cockpit.
 E. Indicating
 When the alarm threshold is reached, the smoke detector triggers the
 following warnings:
 (Ref. Fig. 009A)
 - on the EMER ELEC PWR section of the overhead panel 21VU

 . the SMOKE legend of the GEN 1 LINE pushbutton switch comes on,
 - on the VENTILATION section of the overhead panel 22VU . the FAULT legends of the BLOWER and EXTRACT pushbutton switches come on,
 -the MASTER CAUT light comes on,
 -a warning message is shown on the lower ECAM display unit.
 The single chime (SC) sounds.
 NOTE : When smoke concentration decreases below the alarm threshold, the
____
 smoke detector returns to the initial state.

 F. Control

 (1) Smoke Procedure (Ref. Fig. 010)
 The list of the necessary actions during the smoke procedure comes into view automatically on the lower ECAM display unit while the SMOKE warnings are triggered.
 When these actions are completed, the related lines are cancelled automatically on the lower ECAM display unit (See ATA Ref. 31-51-00).
 The procedure below must be applied:
 (Ref. Fig. 010)

 -------------------------------------------------------------------------------DISPLAY ACTIONS -------------------------------------------------------------------------------
AVIONICS SMOKE LAND ASAP
 . IF PERCEPTIBLE SMOKE :
 . Smoke from avionics compartment is
 detected directly by the crew.

 -OXY MASK/GOGGLES........ON

 . Make sure crew members can speak to control tower each other. Do not use the interphone position to keep the interference of the oxygen-mask breathing noise to a minimum.
 -CAB FANS...............OFF

 . To keep smoke off the cockpit and the cabin.
 -BLOWER................OVRD

 -EXTRACT...............OVRD

 . Avionics ventilation is provided by air conditioning system and extracted overboard: Valve F opening, valve B partial opening, valves A, E and D closing. Blower fan (A) stopping, extract fan (B) remains energized.
 . IF SMOKE AFTER 5MN00S:
 . An electrical procedure is applied to eliminate the cause of the smoke if the smoke emission persists more than 5 mn.
 -EMERG ELEC GEN 1 LINE..OFF
 . GEN 1 LINE contactor opens. GEN 1 remains in operation and supplies one fuel pump in each wing tank. AC BUS 1 is supplied by GEN 2 through bus tie contactor.
 -EMER ELEC PWR.......MAN ON

 . The Ram Air Turbine (RAT) is extended and the emergency generator is connected to the aircraft network.
