Alpha Communications IS485C 4-wire Apartment Intercom Station

Product Description

The ALPHA COMMUNICATIONS IS485C is a 4-wire audio intercom station designed for apartment and multi-tenant residential installations. The unit measures 8 inches wide by 5.5 inches tall and mounts at the individual dwelling unit to allow two-way audio communication between tenants and entry points. It integrates into a 4-wire intercom system and is sold as a single unit. Installation is handled by low-voltage technicians or licensed electricians familiar with intercom and access control wiring. The IS485C suits applications where a simple, reliable audio-only intercom solution is required without video capability.

The IS485C is intended for apartment buildings, condominiums, and similar multi-unit residential facilities. It functions as the tenant-side station in an audio-only intercom system. The unit is part of ALPHA COMMUNICATIONS audio intercom product line and ships as a single station, allowing installers to deploy individual units per tenant or per entry as the system layout requires.

Installation Notes

Installation should be performed by a licensed low-voltage technician or electrician experienced with intercom and access control systems. Power down the intercom system at the controller or power supply before connecting or disconnecting any station wiring. Follow local building codes and the National Electrical Code for low-voltage wiring methods and penetration requirements. Do not exceed the wire run lengths specified by the system controller manufacturer, as excessive resistance can degrade audio quality.
