Fire Alarm Panel & System Retrofit
Discontinued-panel migration, mass-notification integration, communicator conversion, mixed-occupancy splits — engineered, permitted, commissioned.
Fire alarm retrofit work tends to be more complex than people expect. We approach it in phases:
- Existing-conditions survey. Panel model, generation of devices, SLC/IDC topology, programmed logic, monitoring path.
- Migration plan. What devices can be reused (often most of them, with addressable-to-addressable migration), what must be replaced for code or UL-listing reasons, and what the AHJ will require in plan submission.
- Plan submission. Stamped drawings, narrative, battery calcs, voltage drop, AHJ pre-app where useful.
- Cutover. Phased to keep coverage continuous (overnight, weekends, or fire-watch backed).
- Commissioning. Full 100% device test, AHJ acceptance, owner training, documentation handoff.
Common retrofit scenarios we handle
- End-of-life replacement of discontinued legacy panels (e.g., older Notifier, EST, FCI lines)
- Adding NFPA 72 Chapter 24 mass-notification capability to a code-compliant building that just had its use change
- Converting from POTS-line communicators to IP/cellular dual-path (required as POTS sunsets)
- Splitting a single addressable panel across new tenant boundaries with appropriate networking
- Adding voice-evacuation capability where the AHJ now requires it
