The HONEYWELL SILENT KNIGHT 119640B is a cabinet lock designed for use with fire control system enclosures. It provides a secure closure point for fire alarm control panel cabinets, helping to restrict unauthorized access to sensitive life-safety equipment. This type of hardware is typically installed by licensed fire alarm technicians during initial panel installation or as a replacement on existing enclosures. The lock is sold as an individual unit and serves as a direct accessory component within the Silent Knight fire control product line.
This cabinet lock is suited for fire alarm control panel enclosures in commercial and light-commercial applications where access control to the panel interior is required. It is commonly installed during new system commissioning or as a replacement when an existing lock is damaged or lost. Fire alarm service technicians and authorized installers handle this type of fitting during routine service or panel upgrades.
Designed as an OEM-style accessory for Silent Knight fire alarm control panel cabinets. Consult Silent Knight documentation or technical support to confirm fitment with a specific enclosure model before ordering.
Installation should be performed by a licensed fire alarm technician in accordance with NFPA 72 and applicable local codes. Power down or place the fire alarm control panel in a test or service mode before performing any mechanical work on the enclosure. Use appropriate hand tools for lock installation and ensure the latch engages fully before returning the system to normal operation.
