The Comelit 1441 ViP Series 100W Riser Power Supply Unit is a centralized power management module designed specifically for structured access control, video door entry, and intercom systems in residential and commercial buildings. As a "riser" unit, it is engineered to be installed within a building's vertical backbone—typically in a communications closet or electrical riser cabinet—to provide regulated, stable low-voltage DC power to multiple peripheral devices distributed across different floors. The 100-watt output capacity allows it to support a substantial number of door stations, monitors, electromagnetic locks, and other system components over long cable runs, ensuring consistent voltage levels and preventing voltage drop that could lead to unreliable operation.

This power supply incorporates advanced features essential for security system reliability, including redundant backup capability. It can be connected to a 12V sealed lead-acid battery, providing uninterrupted power to the connected life-safety and security devices during a mains power failure. The unit typically includes intelligent charging circuitry to maintain the backup battery in optimal condition and protect it from overcharging or deep discharge. Its construction is designed for permanent installation within an electrical enclosure, featuring robust terminals for secure wiring connections for mains input, battery links, and multiple fused output circuits to protect downstream equipment.

As part of Comelit's ViP (Video Intercom Professional) series, the 1441 is built to integrate seamlessly with the brand's ecosystem of door entry panels, indoor monitors, and access control hardware. It provides a clean, centralized power source that simplifies system installation and maintenance by eliminating the need for multiple, scattered plug-in adapters. By delivering reliable primary and backup power from a single, serviceable location, this unit forms the critical power backbone of a professional-grade access control system, ensuring that critical security and communication functions remain operational at all times, which is paramount for both residential safety and commercial building management.
