Silent Knight SK-FML Fiber Card, Multi Mode Module

Built to deliver reliable, low-latency connectivity for security, surveillance and fire alarm networks, the Silent Knight by Honeywell SK-FML fiber module provides a simple way to extend and harden control panel communications. As a plug-in multimode fiber module, the SK-FML uses ST-style connectors and supports 62.5/125 µm multimode cable with a maximum attenuation of 8 dB, giving you predictable performance across campus and multi-building links. Designed to pair with the Silent Knight SK-NIC network interface card, the SK-FML allows up to 17 panels on a single fiber network, enabling centralized monitoring and single-point communications for easier management. Installers benefit from a compact, card-style form factor that reduces labor time, while facility managers gain improved uptime and lower recurring monitoring costs. The module can be used alongside single-mode or copper segments for flexible, phased upgrades of existing systems. Ideal for fire alarm control panels, access control hubs, and surveillance system backbones, the SK-FML is a practical upgrade for any security infrastructure. Add the SK-FML to your control panel network to increase reliability and simplify monitoring—contact your Honeywell/Silent Knight reseller to configure your solution.
