The Evolve-ML Gray Retrofit Kit converts an existing VS4 Series fire alarm cabinet into a current-generation Evolve Series multi-loop intelligent FACP. Drop-in upgrade: the enclosure stays on the wall, the electronics get replaced, and the site moves to Kidde's current platform without a full rip-and-replace.
Built for the commercial installer
Retrofit kits exist to save labor. Instead of pulling the old cabinet, patching the wall, and running a new backbox, you swap the internals and trim. The gray bezel matches commercial interior aesthetics and ships complete with display module, card cage, circuit boards, and all mounting hardware needed to convert the VS4 enclosure.

What is the difference between the gray and red retrofit kits?
Color of the trim bezel. The GRK (Gray Retrofit Kit) uses a gray bezel suited for commercial interiors. Red versions are available for applications requiring traditional fire alarm red trim.
Why retrofit instead of a full panel replacement?
Retrofitting saves labor and materials. The existing VS4 enclosure stays on the wall, eliminating cabinet removal, wall patching, and new mounting work. The site gets current-generation Evolve electronics without a full rip-and-replace.
