Description
Need a reliable way to know when your phone is ringing—even in loud warehouses, outdoors, or for those who are hard of hearing? The Viking BLK-4-EWP delivers bright, attention-grabbing LED strobe and beacon alerts right from your analog phone line.
This rugged kit includes a powerful blue LED strobe, control module, weatherproof mounting box, and everything you need for quick installation. Whether you're adding visual notification for emergency phones on a campus, in an elevator, or in a busy factory, the BLK-4-EWP turns line activity into unmistakable visual cues.
It works on standard analog lines or PBX station ports and gives you flexible options like flashing on ring only, off-hook (line in use), or both. Plus, its Enhanced Weather Protection (EWP) design handles rain, snow, and humidity without missing a beat.
Expert Take: If your environment is noisy, outdoor, or serves hearing-impaired users, this is one of the most dependable visual ring indicators available. It's not just a light—it's a practical safety and accessibility upgrade. We recommend it highly for both new installs and retrofits.
