The Alpha Communications® IS204A is a universal 4-wire apartment intercom station which combines modern styling with ease of operation to provide natural, clear voice communication and positive door release operation. The white, high-impact, ABS plastic faceplate blends with any decor. The advanced circuitry and versatility permits use in large or small buildings, with one or several entrances.
The 2 vertical and 2 horizontal mounting holes allow the IS204A to mount over a single-gang electrical back box (or mounting ring) or over the IH101 and/or IH102 flush housing(s). This unit replaces at least 2 models of existing intercom stations! With the addition of the optional model AP001 OR AP777 adapter plate, you can now replace 4 existing stations.
