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.

Key benefits

  • Drop-in VS4 conversion: reuses the existing cabinet footprint with no wall modifications
  • Current-generation Evolve platform: brings legacy VS4 sites onto Kidde's latest intelligent fire alarm architecture
  • Complete kit: includes gray trim bezel, display module, card cage, circuit boards, and mounting hardware
  • Multi-loop capable: supports the Evolve-ML multi-loop intelligent configuration
  • Reduced install time: eliminates cabinet removal, wall patching, and new enclosure mounting

FAQs

What does the Evolve-ML Gray Retrofit Kit include?
Complete conversion hardware: gray trim bezel with KIDDE COMMERCIAL branding, Evolve display module with LCD, card cage, circuit boards, and all mounting hardware needed to convert a VS4 Series cabinet.
Does this fit all VS4 Series cabinets?
This kit is designed for VS4 Series enclosures. The existing cabinet remains in place while the internal electronics and trim are replaced with Evolve Series components.
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.
