In today’s world, seconds matter when trouble strikes. The Viking PB-3-IP is a compact VoIP panic button that mounts cleanly under a desk or countertop. Press it once and it quietly dials up to five emergency numbers – no loud alarms, no fuss. The person who answers can listen in silently through the built-in mic or switch to two-way hands-free talk by pressing “#”. It even plays a custom recorded message so responders know exactly where the call is coming from. Powered by PoE over a single network cable, it works with your existing SIP phone system or cloud provider and handles noisy environments thanks to automatic noise canceling. Perfect for K-12 classrooms, college lecture halls, courtrooms, bank teller stations, gas stations, convenience stores, and late-night restaurants – anywhere people need a fast, discreet way to call for help. What we love most: the red LED on the button lights up so the user knows help is on the way, but it stays completely silent for everyone else. The 2-amp relay lets you trigger a strobe light (like the Viking SL-2) or door unlock if needed. Setup is straightforward for any IT admin – program it from a PC on the LAN, remotely, or even from a touch-tone phone. Our Expert Take: This is one of the most reliable and affordable VoIP panic solutions for compliance with safety standards. It’s rugged, built for -40°F to 140°F temps, and backed by Viking’s reputation for USA-designed durability.
