Silent Knight 005815XL Signal Line Circuit Expander for IntelliKnight 5820XL Addressable Fire Control Panel

The 005815XL Signaling Line Circuit (SLC) Expansion Module is designed to expand the addressable device capacity of compatible fire alarm control panels. Featuring RS-485 communication, support for SK and SD addressable devices, and flexible circuit configuration, this module provides an effective solution for extending fire alarm detection and monitoring capabilities.

Designed for compatible 5820XL and 5820XL-EVS fire alarm control panels, the 005815XL adds an additional signaling line circuit to the fire alarm system. Each expansion module supports up to 99 SK protocol detectors and 99 SK protocol modules, or up to 127 SD protocol addressable devices, depending on the selected system configuration.

Up to three 005815XL expansion modules can be installed in a compatible system. This allows the 5820XL system to support up to 508 SD protocol addressable devices across its four signaling line circuits, including the control panel's original SLC.

The expansion module provides signaling line circuit functionality comparable to the control panel's built-in SLC, including support for compatible addressable fire alarm devices and Style 6 (Class A) circuit configurations.

Communication between the expansion module and the main fire alarm control panel is provided through an RS-485 system bus, enabling coordinated device monitoring and system operation.

Designed for installation within compatible 5820XL or 5895XL cabinets, the module offers an integrated expansion solution without requiring a separate standalone fire alarm control panel.

Operating on 24V DC, the 005815XL is suitable for commercial, institutional, and professional fire alarm installations requiring additional addressable detection points.
