A taped message is transmitted on the passenger address system. </span></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">The passenger System ON indicator light comes on white when the passenger oxygen system is electrically supplied. A reset is available to rearm the electrical system after mask re-stowage. The door can be opened manually with a release tool if there is a failure of the container door opening system. When the Timer RESET push button is pushed, the ON white light of the TMR RESET push button comes on. </span></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">The indicator light SYS ON goes off and the taped announcement stops. On the ground, used chemical oxygen units must be replaced and all masks must be re-stowed. The system is reset when the TMR RESET push button is pushed momentarily on the maintenance panel. Manually operated door stops are installed on the container doors. </span></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">These stops are used to do an operational test of the mask release system. In the test position, because of the stops, the doors will  not open fully and the masks will not fall out of the container. </span></p> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_029.jpg" /> <p style="text-align: center"><span style="color: #ff0000"><strong><span style="font-family: arial, helvetica, sans-serif;font-size: 14pt">Passenger Overview</span></strong></span></p> <p style="text-align: justify"><strong><span style="font-size: 18pt;font-family: arial, helvetica, sans-serif">Triggering</span></strong></p> <p style="text-align: justify"><span style="font-size: 18pt;font-family: arial, helvetica, sans-serif">In case of rapid cabin depressurization, oxygen masks are automatically dropped to passengers.</span> <span style="font-size: 18pt;font-family: arial, helvetica, sans-serif">Two types of chemical generators are offered which supply oxygen for 15 minutes or 22 minutes.</span></p> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_031.jpg" /> <p style="text-align: center"><span style="font-size: 14pt;color: #ff0000"><strong><span style="font-family: arial, helvetica, sans-serif">Triggering</span></strong></span></p> <p style="text-align: justify"><span style="color: #000000;font-size: 18pt"><strong><span style="font-family: arial, helvetica, sans-serif">Automatic Operation</span></strong></span></p> <p style="text-align: justify"><strong><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">Starting operation</span></strong></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">The system operates automatically when the altitude pressure switch closes. The TIME DELAY RELAYS 8WR and 9WR are electrically supplied. The busbar 401PP supplies 28 VDC to the oxygen power relay 10WR through the time delay relays 8WR and 9WR. </span></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">The busbar 801XP supplies 115 VAC to the electrical latch assemblies of the emergency oxygen containers. The electrical latch assemblies are supplied from separate 115 VAC circuits on opposite sides of the cabin. The emergency-oxygen container doors open and the oxygen masks are released. The relay 10WR energizes the OXYGEN CONTROL RELAY 11WR. From the relay 11WR, the PASSENGER INFORMATION RELAY 19WR is energized. </span></p> <p style="text-align: justify"><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">A pre-recorded announcement is transmitted over the Passenger Address system.

This ensures that all oxygen unit electrical latches remain energized if a circuit is damaged in the event of engine turbine bursting. The time delay relays (8WR and 9WR) operate 30 seconds after the operation of the altitude pressure switch (16WR). They switch off the supply to the oxygen power relay (10WR) and cause the relays 11WR and 25WR to be de-powered and thus the oxygen container solenoids to be de-powered too.</span></p> <img src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_033.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_034.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_035.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_036.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_037.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_038.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_039.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_040.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_040.jpg" /> <img class="aligncenter" src="https://medialibrary.pk/o/4-OXYGEN-ATA-35_041.jpg" /> <p style="text-align: center"><strong><span style="color: #ff0000;font-size: 14pt;font-family: arial, helvetica, sans-serif">Starting Operation</span></strong></p>   <strong><span style="font-family: arial, helvetica, sans-serif;font-size: 18pt">Fault Operation</span></strong> <span style="font-size: 18pt;font-family: arial, helvetica, sans-serif">When the cabin altitude is more than 14.000 ft and relays 8WR and 9WR remain open after the delay of 30 seconds, a failure on the system occurs.
