EVOLVE-ML Multi-Line Fire Alarm Panel Retrofit Kit for VS4 Series, Red

The EVOLVE-ML Retrofit Kit converts an existing VS4 series fire alarm panel enclosure to the EVOLVE-ML multi-line platform without ripping out the backbox. Drop in the new door assembly, display module, and mounting hardware, reconnect, and the VS4 chassis runs the current EVOLVE-ML intelligent fire alarm system.

Built for the commercial fire alarm installer

Retrofit jobs on Kidde VS4 enclosures no longer require a full enclosure swap. This kit includes everything needed to bring the cabinet up to EVOLVE-ML spec: red trim door with dual windows, multi-line LCD display panel, main circuit board, inner mounting frame, and all associated hardware. Existing field wiring stays in place - the retrofit targets the front-end assembly, not the backbox or field terminations.

Key features

• Upgrades VS4 enclosures in place - no backbox removal, no re-pulling field wiring
• Complete front-end kit: red door, multi-line LCD display, main board, inner panel, and mounting hardware
• EVOLVE-ML multi-line display provides expanded event information and system status at the panel
• Red door with dual window design for visual status and display access
• Drop-in installation reduces labor hours versus full enclosure replacement

System requirements

Requires an existing Kidde VS4 series fire alarm panel enclosure. The retrofit kit replaces the door, display, and front-end electronics while retaining the existing backbox and field wiring connections.
