Product Details

The SRC-1 Secure Relay Controller enables a standard touch tone phone to securely operate a set of timed relay contacts that control a doorstrike or gate controller at a remote location. The SRC-1 is fully user programmable and uses non-volatile memory. The SRC-1 eliminates the possibility of dialing the activation code through the entry phone using a hand held touch tone dialer.

The SRC-1 features a switchable 32V talk battery to allow use with any of Viking’s entry phones (E-Series), doorboxes (W-Series) or hot-line/panel phones (K-Series).

The SRC-1 is installed between the entry phone and the secure phone, and will reject touch tones from the entry phone and only operate the relay if the correct activation code (user programmable) is given from the secure phone.

The SRC-1 also provides up to 32 keyless entry codes to operate the relay from the entry phone with 1 to 6 digits. This feature can be disabled in programming for increased security.
