Honeywell Silent Knight 058950XL Fire Alarm Control Board

Product Description

The HONEYWELL SILENT KNIGHT 058950XL is a replacement PC board designed for use in fire alarm control panel systems. This board serves as the primary processing and control assembly within the panel enclosure, managing alarm input signals, output relays, and system communication functions. It is a direct-service component intended for installation by licensed fire alarm technicians and life-safety system contractors. The 058950XL falls within the fire surge protection category, indicating it incorporates protection circuitry against transient voltage events that can damage sensitive alarm electronics.
