## Summary description

Commax CM-800S is an intercom substation (audio station) designed for use within multi-unit intercom systems. It provides audio communication between residents and entry points, supports standard Commax wiring and integration with compatible master stations, and is intended for indoor installation as a subordinate unit in apartment or office door-entry setups.

## Long description

The Commax CM-800S is an audio intercom substation designed for multi-unit door-entry systems. Intended as an indoor subordinate unit, it provides hands-free two-way voice communication between residents and building entry points when connected to compatible Commax master stations and shared wiring infrastructure. The module supports standard Commax wiring conventions and is built for flush or surface mounting inside apartments, offices or reception areas where basic audio communication and call signaling are required.
Advantages
The CM-800S delivers clear voice transmission and simple operation with a compact housing suitable for confined indoor spaces. It integrates into multi-unit systems without requiring special converters when paired with compatible master stations, enabling centralized call handling and room-level response. Installation follows established Commax wiring practices, which can simplify replacement or expansion of existing installations.
Suitable for
Apartment interiors as subordinate audio stations
Office rooms or small businesses requiring entry-call communication
Multi-dwelling buildings using Commax intercom master stations
Refurbishments where existing Commax wiring infrastructure is retained
When it may not be suitable
The CM-800S is an audio-only substation and does not provide video monitoring or image transmission. It is not a standalone master unit and requires a compatible Commax master station and wiring to operate, so it is unsuitable where independent or wireless door control is required.
Key specifications
Function: indoor audio intercom substation for multi-unit systems
Communication: two-way hands-free audio
Mounting: designed for indoor flush or surface installation
Compatibility: compatible with standard Commax master stations and wiring
Controls: call/answer functionality and local volume adjustments where present
How to use
Install the CM-800S indoors and connect it to the building’s intercom bus according to Commax wiring diagrams and the system master station’s requirements. Once connected, respond to incoming calls from the master station by using the answer control; voice communication is maintained hands-free. For regular operation, ensure the master station supplies power and line signaling. Follow local electrical safety rules and, if needed, have a qualified technician perform wiring and configuration.
What to consider before purchase
Confirm compatibility with the existing Commax master station and wiring layout
Verify that audio-only functionality meets your needs (no video capability)
Plan installation location for indoor use and check mounting type required
Ensure professional installation if you are not familiar with intercom wiring
Usage recommendations
For reliable operation, use the CM-800S as part of a properly configured Commax multi-unit system. Regularly check wiring connections and the master station power supply. If integrating into an older installation, compare wiring terminals and, when necessary, consult Commax technical documentation or a certified installer to avoid compatibility issues.
