Fire-Lite CAC-5X Class Converter Module for MS-5UD-3 and MS-10UD7(E) FACP

Deliver reliable, code-ready protection and enhanced monitoring by converting vulnerable Class B loops to Class A with the Fire-Lite Alarms by Honeywell CAC-5X Class A Converter Module. Designed for MS-series fire alarm control panels, this plug-in converter upgrades five initiating device circuits (Style B to Style D) and converts two notification appliance circuits (Style Y to Style Z) to improve loop survivability and fault isolation. The CAC-5X installs directly on the main controller board (J2 on MS-5UD/MS-10UD; J7 on MS-10UD) so integrators can complete retrofits quickly with minimal disruption. For MS-10UD 10-zone systems, two modules are required to fully convert all zones. That means fewer service calls, reduced downtime, and stronger resilience for your fire alarm, security, and building monitoring systems. Ideal for commercial, institutional, and multi-tenant applications where continuous operation and reliable notification are critical. Add the CAC-5X to your next panel upgrade to bolster circuit integrity and simplify maintenance—order or contact sales to specify for your project.

• Upgrade MS-5UD/MS-10UD panels to Class A for greater circuit survivability and continuous monitoring
• Converts five Class B initiating device circuits and two notification appliance circuits to Class A for improved fault tolerance
• Simple plug-in installation to the main controller (J2/J7), minimizing installation time and system downtime
• Allows OEM-style isolation so a single open or short won’t disable the entire loop, enhancing reliability for security and fire monitoring
• Compact, field-installable module—ideal for retrofits and upgrades in commercial fire alarm control panel deployments
