Description
In busy facilities where a ringing phone can go unheard over ambient noise — warehouses, break rooms, shop floors, or large open offices — the Viking SRL-1 adds both a loud audible alert and a bright visual ring indicator so incoming calls are never missed.
The SRL-1 converts analog ringing signals or dry contact closures into a selectable high-decibel audible alert paired with an LED visual indicator. This combination ensures staff are notified of incoming calls even when they're at a distance from the phone or working in noisy conditions. It is well-suited for enterprise and industrial telecom environments where standard phone ringing alone does not provide sufficient coverage.
Our Expert Take: The SRL-1 is the right add-on when ambient noise is masking incoming calls or when someone needs to know about a ringing line from across the room. The paired audio-plus-LED approach covers both high-noise environments and users who need visual notification.
