Comelit 4888CU SIMPLEBUS Color Mixer

Enable reliable, consolidated intercom power and signal management with the Comelit 4888CU SIMPLEBUS Color Mixer. Designed for installers and integrators, this mixer + power supply combines SIMPLEBUS 2-wire mixing with a dedicated 120V AC power source in a compact 8-module DIN enclosure, reducing cabinet clutter and installation time. The unit supports up to 100 devices (door-entry phones and monitors) distributed over four outputs, and provides supervised monitor power to the riser while offering line termination and a visible LED for short-circuit detection — helping you maintain uptime across security and surveillance systems. Because it handles intercom communication and alarm signal management without an external interface or porter switchboard, the 4888CU is ideal for apartment buildings, offices and light-commercial deployments where streamlined monitoring and reliable voice/video entry are essential. Compatible with Comelit Video SIMPLEBUS Color systems and built for DIN-rail mounting, it delivers a professional, serviceable solution for modern access control and monitoring projects.
