Multi-zone ERCES booster for the SHIELD EXTEND platform. Drives multiple Coverage Units across a building or campus from a single Network Unit — used where the SOLO's single-zone footprint isn't enough and AHJ-mandated coverage thresholds (typically 95% of critical areas, 90% general areas) require zone-by-zone tuning. The Class B Network Unit is paired with Class B CUs for AHJ designs requiring Class B operation.
