System 7000 is a self-contained Thunderbolt system that is capable of operating from a municipal power supply or from the built-in engine driven AC generator. Speculation suggests that this was an idea as a failsafe system for the Thunderbolt in the case of power loss before battery-backup hit the mainstream.
The system consists of a modified Thunderbolt siren, a RadioTrol(optional), and an engine driven AC generator. The system is housed in a corrosion resistant aluminum and steel shelter.
