Topology patterns

From command-control to legislative-acoustic — each pattern carries a confidence score and observed-in project list.

Lifecycle rules

Refresh-cadence rules grounded in real degradation behaviour, not warranty windows.

· Topology patterns

· Lifecycle rules

  • VRLA battery bank, >= 30 months in service

    tier gold · refresh @ 36 mo

    VRLA capacity degrades 5-8% per year nominal, accelerating above 30°C. Refresh at 36 months preserves the holdover guarantee.

  • Fine-pitch LED wall, >= 5 years in service

    tier gold · refresh @ 18 mo

    Colour-uniformity drift over 7-9 year horizon; panel-by-panel re-calibration every 18 months preserves chamber-grade visual coherence.

  • Wi-Fi 6 AP plant, >= 5 years in service

    tier silver · refresh @ 60 mo

    Wi-Fi 7 generational refresh window opens at 5-7 years; Cat6A backbone supports the next generation without re-cabling.

  • Honeywell IMPACT NVR fleet, between firmware refresh cycles

    tier silver · refresh @ 12 mo

    Firmware-driven analytics evolve faster than camera hardware; configuration baseline export + analytics rule review at every firmware cycle.

  • Addressable fire system in service, post-occupancy changes

    tier gold · refresh @ 12 mo

    Occupancy changes (department moves, suite reallocations) invalidate parts of the C&E matrix. Annual review against the architect-of-record floor plan keeps evacuation behaviour predictable.

  • High-SPL audience loudspeakers, >= 4 years

    tier silver · refresh @ 48 mo

    Compression driver diaphragms fatigue under sustained SPL; impedance + sensitivity sweep flags failing drivers before audience perception.

  • OFC backbone, >= 7 years in service

    tier gold · refresh @ 84 mo

    Connector loss creeps over 7-10 year horizon; OTDR survey identifies degraded splices before they manifest as link-flap events.
