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 gateways:
RS-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 gateway location    
Note
A network interface card is required on the gateway to enable Silver 
Network communications.
Note
Use low capacitance shielded twisted pair data cable for RS-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 gateway 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
