Kidde VS1-RE Replacement Electronics Assemby Kit

The Kidde VS1-RE kit provides a complete replacement electronics assembly for VS1-series fire-alarm control panels. It includes the main controller board, four-line LCD display, power-supply chassis, and ribbon harnesses that mount on the existing VS1 cabinet backplate. Installing the VS1-RE restores all original functions such as the Signature SLC loop, two NACs, a 3.75 A power supply, dual Form C relays, strobe synchronization, ANSI Temporal coding, and programmable front-panel switches without disturbing field wiring or the enclosure.
