Sunwise Technology Completes Next-Generation All-IP Public Address System for Hong Kong United Hospital — Turn‑key EPC delivery underpins safer, smarter healthcare communications
Hong Kong, 4 July 2025 — Sunwise Technology PTE. LTD. (“Sunwise”) today announced the successful hand‑over of a hospital‑wide Public Address (PA) system upgrade at Hong Kong United Hospital. Acting as EPC contractor, Sunwise supplied, installed, commissioned and now maintains a KNTECH all‑digital IP PA solution that provides crystal‑clear emergency paging, routine announcements and queue‑management integration across every ward and public space.
Project Highlights
True high-definition audio: 24‑bit / 48 kHz Audio‑over‑IP transport delivers CD‑quality intelligibility, a major leap from legacy 8 kHz analogue systems.
Enterprise‑grade redundancy: Dual‑network architecture, 8 + 1 spare amplifier channels and A/B speaker‑line loops keep broadcasts alive even during single‑point failures.
Standards‑led compliance: System core, amplifiers and call stations hold EN 54‑16, ISO 7240‑16 and IEC 62368 certifications—meeting stringent life‑safety codes required for hospital environments.
Smart operations: Web‑based control, NTP/GPS synchronisation, ambient‑noise adaptive volume and queue‑calling interfaces streamline daily workflows while guaranteeing “one‑button” emergency override.
Long‑duration back‑up power: Two 6 kVA UPS units in 1 + 1 hot‑standby configuration sustain up to six hours of broadcast during mains outages.
