Silent Knight 6820EVSBD — the 6820EVS control board, supplied on its own rather than as a complete cabinet.
A complete 6820EVS ships as four items: the main circuit board with display, a backbox with door, a bag holding two keys, screws, cables and ten 4.7 kΩ end-of-line resistors, and the manual. A board-only order covers the electronics, so plan on reusing the backbox, door and keys already on the wall.
- Intelligent addressable fire alarm control panel with integrated emergency voice system
- One onboard SLC: 159 SK detectors plus 159 SK modules, or 127 SD devices; expandable to 1110 (SK) or 635 (SD) points
- Six Flexput circuits for NAC or auxiliary power, 3 A per circuit and 6 A total
- 120 VAC, 60 Hz, 3.3 A input; battery charger capacity 7 to 35 AH
- SBUS supports 24 devices; up to 17 panels networked
- Certified to UL 864 10th Edition and UL 2572 2nd Edition
This is the EVS board, not the plain 6820 board, and SK and SD devices cannot be mixed on one system.
