Electrical & Surveillance parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat it does
1 Battery 12V 2×
2 Alternator 3 parts 1×
3 Wire Bundle 1× Group of insulated conductors cut to length, terminated, and bound together to carry power and signals between the assemblies of a machine.
4 Surveillance Camera 2 parts 6× cell cameras
5 Digital Video Recorder 3 parts 1× recorder
6 Cell Intercom 2 parts 1× cell intercom
7 Crew Radio 2 parts 1× crew radio
8 Connector 16× Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering.
9 Relay 4× Electromechanical switch in which a small coil current closes or opens contacts rated for a much larger load, isolating control circuits from what they switch.
