Extraction Parachute Jettison Device (EPJD). The EPJD couples the extraction line with the 3-point-link
assembly. One device is required for each platform. In normal operation, the extraction parachute is
deployed and the payload exits the aircraft. In the event the extraction parachute is deployed and the
payload fails to exit the aircraft, the load master can activate the JETTISON SWITCH on the control box
which fires the squibs in the system and releases the extraction parachute(s) from the payload(s).
Y-Connector. The Y-connector contains a LAMP TEST switch, a blue indicator Light Emitting Diode (LED),
a connector for the platform cable, and two connectors for the interconnecting cables. The LAMP TEST
switch, when pressed, will illuminate the blue LEDs when the system is installed and powered ON. The
LED, when lit, indicates that one or both circuits from the Y-connector to the squib are intact. The internal
circuit contains capacitors for storing the energy required to fire the squibs and has solid-state switches that
are actuated by the JETTISON SWITCH on the control box. The Y-connector is attached to the Y-
connector mounting box; one set is used for each platform.
