Silver Network wiring connections
Silver Network specifications
• Data rate - fixed 57.6 k bps
• Maximum 60 devices spread over up to 4 independent network loops
• Two communication Channels (Side A, Side B)
• Response time - 1 second, or less from alarm source to Network Manager (per loop)
• Network termination - not required
• Transmission media/maximum separation distances between processors:
• EIA-422 copper wire - 1.2 km (0.75 mi.) - 2 pairs per Channel
• Multi-mode fiber optic cable (820 nm) - 2.2 km (1.4 mi.) - 2 fibers per Channel - optical
power budget 8 dB
• Single-mode fiber optic cable (1310 nm) - 10 km (6.2 mi.) - 2 fibers per Channel - optical
power budget 8 dB
• Ethernet - Category 5 cable, 100 m between PoE switch and processor location
Note A network interface card is required to enable Silver Network
communications between a FlexZone processor and the Silver Network
manager.
Note For groups of FlexZone processors that communicate over the sensor
cables, only the processor that is connected directly to the Silver
Network requires an NIC.
Note Use low capacitance shielded twisted pair data cable for EIA-422,
62.5/125 multi-mode fiber optic cable,
9/125 single-mode fiber optic cable, and
Category 5 Ethernet cable.
The maximum separation distances require high quality transmission
media and sound installation practices.
CAUTION Both the FlexZone processor and the network interface cards contain
static sensitive components. Follow proper ESD handling procedures
when handling the cards.
Ensure the expansion header on the NIC is properly lined up and fully
seated in T2 on the processor.
