The C-200 allows single line telephones or a telephone system to share a phone line with a single Viking entry phone. Tenants may answer an entry phone call and converse with the visitor.
The C-200 provides a Call Waiting tone when the phone line is in use.
Tenants may call out to the entry phone for monitoring purposes. Auxiliary contacts are provided to operate a doorbell, or activate a camera, lights, etc.
If additional features (such as doorstrike, multiple entry phones with caller ID, and keyless entry) are needed, use the Viking model C-2000B.
