Silent Knight 6815 SLC Loop Expander for SK Devices 006815

The 6815 Intelligent Addressable Signaling Line Circuit (SLC) Expander is a professional fire alarm expansion module designed to increase the addressable device capacity of compatible fire alarm control panels. Featuring support for SK protocol devices, RS-485 communication, and flexible wired and wireless detection configurations, this module provides additional capacity for large and complex fire alarm installations.

Designed for compatible 6820 and 6820EVS fire alarm control panels, the 6815 adds an additional signaling line circuit with functionality comparable to the panel's built-in SLC. Each expansion loop supports up to 159 compatible addressable detectors and 159 addressable modules, providing a maximum of 318 addressable points per loop.

The 6815 provides flexible expansion for fire alarm systems supporting up to 1,110 total SK protocol points. The number of expansion modules that can be installed depends on the control panel's supported configurations, available mounting space, and maximum addressable point capacity.

Communication between the expansion module and the main fire alarm control panel is established through an RS-485 system bus. An onboard green LED flashes to indicate proper communication, allowing technicians to verify the module's operating status.

The module also supports compatible wireless fire detection systems through an optional WSK-WGI wireless gateway. The gateway connects to an SK protocol signaling line circuit, allowing supported wireless detection devices to communicate with the control panel.

Compatible wireless devices can be integrated alongside hardwired addressable devices on the same SLC, providing additional flexibility for installations where conventional cabling is difficult or impractical.

For convenient installation, up to two additional 6815 SLC expansion modules can be housed within a compatible fire alarm control panel enclosure. Additional mounting arrangements may be supported using compatible expansion mounting accessories.

Ideal for commercial buildings, institutional facilities, campuses, and other complex fire protection installations, the 6815 offers a scalable solution for expanding intelligent addressable fire alarm systems.
