Silver Network
Network control
• Network Manager (Windows-based software) - 1 required per Silver
Network, max. 10 NMs on one PC, communicates with and controls
Silver Network based sensors, reports status to Windows-based
security management systems via TCP/IP communications
Number of devices
• up to 60 sensors per Silver Network
Network transmission media/
Device separation distance
• EIA-422 - 1.2 km (1300 yd.)
• multi-mode fiber - 2.2 km (2400 yd.)
• single-mode fiber - 10 km (10900 yd.)
• OC2 sensor cable - 800 m (875 yd.)
• SC1/SC2 sensor cable - 400 m (437 yd.)

(for each network loop, not using Ethernet communications)
Network Interface Unit
• two variants - multi-mode fiber, single-mode fiber
• NIU - 1 required per Silver Network, 2 required for full redundancy,
dual channel (A-side, B-side),
