EST3 Network Communications
Network and Audio Data Upgrades
Communication Methods
Standard Copper Cable, RS485 Card
Fiber Optic Interface
Multimode
Single Mode, High and Low Output
Telco Copper Lines, Short Haul Modem
Common Communication Features
Style 4 or 7 (Class ‘B’ or ‘A’)
Can switch media on the same network
There are rules
3-RS485x Communication Card
#18 AWG Copper, up to 5000’ over 3 NodesNetwork Data, 90Ω, .3 µf
Audio Data, 90Ω, .09 µf
Use 3-RS485B for…Class ‘B’ Network Data
Class ‘A’ Network Data
Class ‘B” Audio Data
Use 3-RS485A for…above plus Class ‘A’ Audio Data
3-FIBMB2 Fiber Optic Interface
Network Data & Audio on the same board
Multimode & Single Mode Fiber both Lo and High output
Mix Fiber [TYPES] and RS485 Copper Communications
3-FIBMB2 Fiber Optic Interface
SMXLO2 Single Mode Transceiver
Approx. 8.7 miles, 16 dBm budget
SMXHI2 Single Mode Transceiver
Approx. 24.85 miles, 29 dBm budget
MMXVR Multimode Transceiver
Approx 7000 feet, 10 dBm budget
Transitions
Copper to Fiber
Any Fiber to Any Fiber
NO Fiber transition to Short Haul at the same node, need copper between
NO Fiber or Short Haul at an Annunciator, copper only
*Retrofit or upgrades to existing EST3 single mode systems require specific considerations.
Fiber Benefits & Applications
Immune to electrical noise
Use through hazardous atmospheres
High level of security
Resist effects of moisture
Eliminates ground faults
Cost Considerations
MultimodeHigher cost fiber, lower cost electronics
ST Connectors (physical connector)
Single ModeLower cost fiber, higher cost electronics
SC Connectors (physical connector)
Driving Factor = Distance
Performance is Equal but for distance

Short Haul Modem 3-NSHMx Up to 6 miles between nodes
Uses 2 Pair existing copper telco lines (must have continuity)
Integrated test modes
Accessories transient suppression & ground fault
Media Switch Conditions: Standard copper to Short Haul
Short Haul to standard copper
Short Haul to Short Haul

How the Short Hauls fit in?
Interface Card plugs into RS485 Slot on CPU
Ribbon cable to NSHMx
NSHMx to Chassis
3-NSHMx Ground Fault Detection
GFD
Short Haul modem wiring is opto isolated
GFD module monitors ground fault on isolated wires
Requires 24 VDC & SIGA-CT1 to monitor
SIGA-CT1PS
G GGFD
2 Pair
Short Haul Design Considerations
Network Data Only – No Audio
Cannot use at Annunciators
Requires two pairs, runs full duplex
Cannot have Short Haul and Fiber at the same node
