Description
Managing door strikes and gate access across multiple entry points shouldn't require proprietary hardware or complicated installs — the Viking SRC-1 gives you secure, touch-tone programmable relay control that works with virtually any analog entry phone or door box you already have in place.
The SRC-1 connects alongside Viking door boxes, entry phones, and hotline panel phones to give you programmable control over door strikes and gates from any touch-tone phone. A six-digit security code protects access to programming, and non-volatile memory keeps all your settings intact through power outages. With support for up to 32 keyless entry codes, a programmable relay activation time, and a trigger input for contact closures from postal locks or request-to-exit devices, this controller handles the full range of real-world access scenarios without extra equipment.
The SRC-1 runs on any 12–24V AC or DC power source, making it easy to integrate into new or existing installations. Built-in LEDs provide instant visual confirmation of power status and relay activation, so you always know the system is working. Whether you're securing a single door in a small office or managing entry across a multi-tenant building, the SRC-1 fits cleanly into your setup.
Our Expert Take: The SRC-1 is a natural companion to Viking entry phones like the E-10A, E-20B, E-30, E-40, E-50, or K-1700-3 when you need to keep relay control separate from the entry phone itself — particularly in high-security applications where you want an additional layer of programmable code protection. The switchable 32V talk battery is a practical detail that makes compatibility with a wider range of door boxes straightforward, and the trigger input for request-to-exit or postal lock contact closures adds flexibility you'll appreciate in commercial lobby and multi-tenant deployments.
