– CAT6 UTP HF cabling throughout for camera connectivity
Emergency Announcement System:
– 300W amplifier system with 5 distinct zones
– Ceiling-mounted speakers with line transformers
– UHF handheld wireless microphone system
– Announcement unit with zone selection capabilities
– Integration with fire detection system for automatic emergency announcements
– 3×1.5 mm² LIH(st)H cabling for speaker connections
Technical Specifications: All active equipment housed in a 19″ 32U rack cabinet with UPS power backup. Both systems share infrastructure with the building’s data network but maintain separate network segments for security. The CCTV system includes fiber optic connectivity (4-core SM/FO) to the monitoring center in another building.
