The SK-FIRE-CO-W is an addressable combination photoelectric smoke and carbon monoxide detector for the Silent Knight SK protocol SLC. A single device occupies one addressable point and simultaneously reports smoke and CO conditions independently to the 5820XL or 6500 series fire alarm control panel (a Honeywell brand). Its UL 268 and UL 2075 dual listing is suitable for code-compliant combined fire and CO detection in commercial occupancies.

Verify panel/device family compatibility before ordering.
