Silent Knight 005815XL — the 5815XL signaling line circuit expander, which adds an SLC of Hochiki SD addressable devices to a Silent Knight fire alarm control panel.
The board is an add-on, not something the panel needs to run. It hangs off the panel SBUS on RS-485, takes an ID from onboard DIP switches and is added in programming, after which its loop behaves like the SLC built into the panel, Class A included.
- Supports 127 SD addressable devices per expander
- Compatible with the Silent Knight 6820 and 6820EVS control panels
- Communicates over the RS-485 system bus; a green LED blinks when it is healthy
- Standard wire is acceptable for the SLC — twisted pair and shield are not required
- 24 VDC; 4.2 in. high by 4.8 in. wide; 32°F to 120°F
- UL 864 10th Edition and UL 2572 2nd Edition; UL certified S2766, FDNY, CSFM and FM
Two boards fit a compatible panel cabinet, a 5895XL power supply module cabinet, or the 5815RMK remote mounting kit. Earlier revisions of this data sheet also listed the 5820XL and 5820XL-EVS IntelliKnight panels; the current revision does not.
