Controlled PLC programming for fire and safety interfaces

We develop and modify PLC logic for defined fire-system functions, test every input and output and preserve the software and change records needed for future support.

  1. 01
    Functional description and I/O schedule We agree the operating sequence, signal list, alarm priorities, delays, permissives, manual controls and safe states before coding.
  2. 02
    PLC software and interface programming We implement the approved logic and communications for fire panels, pumps, valves, ventilation, shutdowns and monitoring equipment.
  3. 03
    Simulation and site acceptance testing We simulate inputs, verify outputs and fail-safe behaviour, then test the complete sequence with connected equipment and project stakeholders.
  4. 04
    Backups, versions and change report We hand over labelled program backups, software and firmware details, I/O records, test results and a clear description of every change.
