6815 Signaling Line Circuit Expander

Silent Knight’s Signalling Line Circuit is used as an 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. It provides a powerful way to customize configurations in large or complex installs.

6815 communicates with the FACP via an RS 485 system bus. A green LED on the 6815 board blinks to indicate good communication. If an addressable device on a 6815 fails, the loop communicates the failure to the 6820 and 6820EVS and continues to operate normally.

• Available 1,110 points make flexibility, new design and installation opportunities possible
• Up to two additional 6815 SLCs can be securely housed in one FACP, thus limiting the need for separate housing
• Useful for installations where buildings are connected for multi-site benefits using fiber optic or copper wiring
