This listing is for the internal electronics core and original technical manual for a Kidde Vigilant VS series fire alarm system. These components were pulled from a working system during a planned facility upgrade.

Condition Note: Because I do not have the specialized bench-testing equipment required to verify these boards outside of a full cabinet, they are being sold For Parts or Not Working. This is a standard precaution for secondary market life-safety electronics.

Main Control Board: Primary PCB for VS1/VS4 series units.

Loop Expansion Subassembly: Model 3KAM (UL Listed S3000 Fire Alarm Subassembly / Issue No. BK-761). Note: The red mark on the large capacitor is a factory QA inspection stamp, not a leak.

The manual is intact and clean, a valuable asset for field programming and troubleshooting.
