Silent Knight 6815 Signalling Line Circuit Expander

Silent Knight 6815 Signalling Line Circuit Expander [NEW] Silent Knight’s Signalling Line Circuit is used as a loop expander with Honeywell Silent Knight 6820 or 6820EVS fire alarm control panels using System Sensor protocol. 6815 can also be used for SWIFT wireless detection. The integrated 6815 can be used for SWIFT wireless devices to communicate with the FACP through a gateway (WSK-WGI) that connects to the SLC using SK protocol. The 6815 communicates with the FACP via an RS 485 system bus. Up to two additional 6815 SLCs can be securely housed in one FACP, thus limiting the need for separate housing.
