Silent Knight 006815 Silent Knight 6815 SLC Loop Expander for SK Devices

Upgrade your fire and security monitoring with the Silent Knight by Honeywell 006815 SLC loop expander — designed to expand addressable device capacity and simplify complex system designs. This signaling line circuit (SLC) expander adds an additional 159 SK-addressable devices per module, giving integrators and facility managers the flexibility to build larger or multi-site networks without reworking existing infrastructure. The 6815 communicates over an RS-485 system bus to Silent Knight 6820 and 6820EVS FACPs (supporting up to 1,110 points), and operates on standard 24V DC power for reliable, industry-grade performance. It also supports SWIFT wireless gateways, allowing hybrid wired/wireless deployments when hard-wiring is impractical—ideal for retrofits, remote wings, or campus surveillance integration. A green LED provides instant loop status to speed diagnostics and reduce downtime. Whether you’re specifying a new fire alarm design, expanding a commercial building’s security system, or linking multiple sites, the Silent Knight 6815 SLC loop expander delivers predictable scalability and simplified monitoring. Contact your distributor or order now to add flexibility and resilience to your fire alarm and security network.

• Expand system capacity and flexibility: add 159 addressable SK devices per module to scale large or multi-building fire and security networks.
• Simplified integration with existing FACPs: native SK protocol compatibility with Silent Knight 6820/6820EVS panels for seamless deployment and monitoring.
• Hybrid wired/wireless support: use SWIFT wireless gateways on the same SLC to combine hard-wired and wireless detection for challenging installs.
• Reliable communications: RS-485 system-bus connectivity and a green status LED provide clear loop health and reduce troubleshooting time.
• Space and cost savings: mount up to two additional 6815 SLCs in an FACP enclosure to minimize separate housings and installation labor.
• Industry-grade performance: 24V DC operation and wide compatibility enable dependable fire alarm, security, and site surveillance integrations.
