Answer and Control Your Door Virtually Anywhere – C-500 by Viking Electronics

HUDSON, WI – September 14, 2018

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.

User programmable entry phone “Caller ID” is provided to the local phones. A built-in five number dialer can call an outside line if there is no answer on the local phone. If the outside call is busy or ring no answer, the C-500 can call up to four more numbers. Tenants may also call the entry phones for monitoring purposes or enter touch tone commands to activate, deactivate or toggle the relay contacts.

The C-500 allows up to 6 permanent keyless entry codes, 2 “one time use” entry codes and 1 toggle entry code for each door. The C-500 provides optional entry phone distinctive ring, two trigger inputs for “Request to Exit” and field programmable Caller ID or beep tones when answered to indicate which door is activated.
