Good to Know

Here’s where it gets interesting: this mixer empowers you to manage alarm signals and enables direct intercommunication between users, all without the need for an interface or porter switchboard. Plus, it supports call addressing for up to a staggering 120,000 users.

However, please note that the Comelit 4888C Power Supply Mixer is not compatible with the Simplebus TOP system in specific scenarios: when main and secondary switchboards coexist, when the intercom function without an interface is active, and when the alarm function is in use within the system.

For a dependable and efficient power supply mixer tailored for your Simplebus2 system, the Comelit 4888C is the ultimate choice.
