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. A thermostatically controlled fan is used in systems intended for use in consistently hot climates. An optional keylock switch controlled intrusion alarm system may be included to discourage unauthorized access into the system.
