Edwards 3-RS485B Network Communications Card

Edwards 3-RS485B Network Communications CardThe 3 RS485B card provides a Class B (Style 4) or Class A (Style 7) circuit for network communications signals. And a second Class B (Style 4) circuit for the digitized audio signals. Network messages the Network Communications card receives a re re transmitted to the next network node. Re transmission maximizes the wire run lengths between nodes. With 64 nodes, miles of network length is possible. Fail safe mechanisms built into the card directly

Operating voltage: 15

Universal Compatibility: Designed to work seamlessly with multiple Silent Knight detector heads

Engineered for seamless integration

profile installation and uses the model SD505-6AB base

Each relay output is intended for Form C switching applications which do not require wiring supervision for the load circuit

When connected to the 2W-MOD2 loop test/maintenance module or a panel with the i3 protocol

Notifier FSP-851(A) Series intelligent plug-in smoke detectors with integral communication provide features that surpass conventional detectors

Seamless Integration

This allows an installer to pre-wire bases (included with heads)

Additionally

provides complete short circuit isolation for NFPA 72

Industrial Facilities – Ensures effective monitoring of large-scale fire safety networks
