· 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.
