Edwards 3-RS485B Network Communications Card Universal Compatibility: Designed to work

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

Operating voltage: 15

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

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

Edwards 3-RS485B Network Communications Card Universal Compatibility: Designed to workThe 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
