The C-500 advanced entry phone controller allows single line telephones or a telephone system to share a phone line with two Viking entry phones. This powerful controller provides call forwarding, relay control, keyless entry and more. “It’s a feature rich access controller in a very small package.” – Joanne Minke, Product Specialist, Viking Electronics, Inc.
Up to four C-500’s can also be connected in series allowing control of up to eight entry points. Tenants may answer an entry phone call, converse with the visitor and let them in with a touch tone command which activates a relay to control a gate or door strike.
