Audible and Visual Workplace Alert System
Give everyone in your factory or warehouse a clear instruction the moment something goes wrong – a medical emergency, a fire, severe weather, or any event in your emergency response plan. The Netbell IP paging system plays a distinct tone and pre-recorded message, the VidiMax operational visualization platform shows matching instructions on your screens, and supervisors can page live from the phones they already use.

Trusted by industry leaders


















Machinery, forklifts, and hearing protection can make an announcement difficult to hear. A workplace emergency alarm system needs to account for those conditions and communicate the actions in your emergency plan.
Netbell provides the audible paging, and VidiMax adds visual alerts to the TVs and monitors you already have. Together, they help your employees hear the warning and see what to do, and help your facility meet the OSHA 29 CFR 1910.165 employee alarm system requirements.
Place network push-button stations at practical locations such as supervisor stations and reception, and assign each button a pre-recorded message to match your emergency code. Supervisors can carry a wireless key fob, and anyone at a computer can use the free QuickAction app.
Use IP horn speakers in production and warehouse areas, and wall or ceiling speakers in offices and hallways. Build paging groups around those spaces so messages can go to selected areas or across the facility.
How It works
Netbell and VidiMax work together over your facility’s network for audible & visual alerts

Staff press a button or use QuickAction. Connected equipment or a National Weather Service warning can also start it automatically.

The Netbell-NTG-B sends the emergency message to your IP speakers. Staff can follow up with live updates from an IP microphone or a phone.

VidiMax puts the same emergency code and instructions on the screens, so people in the loud areas see it even if they missed the page.

When the emergency is over, the system can trigger an all-clear message over speakers and displays so workers know it’s safe to resume operations.
The Platform
PoE-powered speakers across your facility, driven by a tone generator that stores your pre-recorded emergency messages. Trigger by push button, key fob, or automatically through VidiMax.
Pushes full-screen emergency alerts to every HDMI-connected TV or monitor in your facility – critical for noisy areas where speakers alone won’t reach workers. Integrates directly with the Netbell-NTG-B.

Tell us your emergency codes and how you want to trigger them. A floor plan helps, but you don’t need one to get started.
It’s a system that warns everyone in your building about an emergency and tells them what to do. Linortek’s system works on-site, with Netbell IP speakers for the spoken message and VidiMax screens for the written one, triggered by a button, an app, or your connected equipment.
Start with who you need to reach and where. The alarm has to be heard over the noise in every area, so loud spots need horn speakers, and areas where people wear hearing protection need screens too. Each emergency should have its own signal your people recognize, the buttons should be where someone will actually be when things go wrong, and the system should be easy to test. We’re happy to help you work through it with a free system design.
When something goes wrong – a fire, a lockdown, severe weather – you need everyone to know in seconds, not minutes. An emergency alert system lets you trigger a clear audible and visual warning across your whole facility from one button, so everyone gets the same instruction at the same time.
Yes. Supervisors can page live from your VoIP phones through the AU-711-SIP gateway. Pre-recorded alerts can be set off with a wired button, a wireless key fob, or our free QuickAction app, or by tying the system into your fire, security, or gas detection equipment through a digital input or our RESTful API. With VidiMax, it also watches National Weather Service alerts and sends the warning on its own.
Audible alerts are spoken messages or tones over the speakers. Visual alerts are on-screen messages on VidiMax displays or LED signs – “LOCKDOWN – SHELTER IN PLACE,” for example. Pairing both means the message still gets through in a noisy plant, or for anyone who can’t hear the announcement.
They’re mostly two names for the same job – getting a warning out to everyone fast. “Alert system” usually means the audible and visual warning inside your building; “notification system” often adds ways to reach people off-site, like text or email. Ours handles the on-site side – instant audible and visual alerts across your whole facility – and can hand off to other tools when you also need to reach people who aren’t there.
It’s used across factories, warehouses, offices, construction sites, and multi-building campuses – anywhere you need everyone warned at once. It handles fire and evacuation, lockdowns, severe weather, and any custom alert you set up, each with its own message on the speakers and displays.
Text and app services are good for reaching people off-site or on their phones, but they depend on everyone having the app, a signal, and actually looking down. Ours is the in-building layer – loud audible alerts and on-screen messages that interrupt what people are doing right where they are.
It depends on your building and who you need to reach, but the practical checklist is short: it reaches everyone at once (loud enough for noisy areas, visible for anyone who can’t hear it), it’s one-button simple in a real emergency, and it doesn’t lock you into monthly fees. Linortek’s system is built around exactly that – audible plus visual, triggered from a button, key fob, or your existing systems, with no subscription.
Yes. Everything runs on your local network, and each device stores its own settings and messages, so paging, buttons, and scheduled signals keep working without the internet. The only feature that needs it is VidiMax weather alerts. Because the speakers get their audio and power over your network, we recommend putting your network switches on battery backup (UPS).
On the device. Every Linortek device has its own built-in server that stores its settings and messages, so nothing lives in the cloud.
