Product Description P/N: 6815
Description
The Silent Knight 6815 is a dedicated signaling line circuit (SLC) expander module designed to increase the addressable point capacity of commercial fire alarm control panels. This printed circuit board connects via an RS-485 system bus to support an additional 159 System Sensor (SK) detectors and 159 SK modules on a single data loop. By distributing network communication capabilities, the expander allows for the seamless integration of supplementary life safety devices across expanding facility infrastructure.

Information About 6815
The 6815 is an advanced solid-state expansion board engineered for direct compatibility with Honeywell Silent Knight 6820 and 6820EVS addressable fire alarm panels. It operates using the standardized System Sensor (SK) communication protocol to interface smoothly with both hardwired and SWIFT wireless fire detection devices. Fire protection technicians deploy this expander within distributed commercial life safety systems to customize and scale device configurations without replacing the primary control chassis. The internal architecture features integrated LED diagnostics to visually confirm active network communication and immediately report isolated loop failures to the central processing hub.
Key Features:
● Expanded Device Capacity: Supports up to 159 additional System Sensor (SK) detectors and 159 control modules per loop to maximize network reach.
● RS-485 System Bus: Communicates securely with the primary fire alarm control panel utilizing a high-speed, supervised serial connection.
● Protocol Compatibility: Engineered exclusively for use with standard SK and IDP addressable protocols, ensuring seamless sensor integration.
● Wireless Integration Support: Facilitates the addition of SWIFT wireless fire detection equipment alongside traditional hardwired sensors on the identical circuit.
● Active LED Diagnostics: Includes an onboard green indicator light that blinks continuously to visually confirm stable digital communication.
● Compact Board Design: Features a low-profile printed circuit architecture that mounts securely within the main panel enclosure or an approved remote cabinet.
● Standard Wiring Infrastructure: Operates efficiently over standard unshielded, non-twisted copper wiring to minimize installation complexity.
The 6815 delivers the reliability and precision required for scalable fire detection and comprehensive life safety monitoring in commercial environments.
