23 Minutes of Downtime.
Not a Minute of It in Any Report.
An operator hits the button at the station and it reaches the wrist of whoever fixes it, Materials, Maintenance or Quality. A machine can raise the same call on its own. The clock starts the moment the button goes down, so the waiting nobody logs today shows up in a report by station and by shift.
Free for 60 days, hardware ships at no cost and goes back free · starts with a 30-minute call · nothing of ours joins your network, not your Wi-Fi and not the internet.
Other problems we hear every week
🚶 Operators leave the station to find help 40+ min a shift
"Our operators leave their stations for 10+ minutes just to find a supervisor, lead, or maintenance person. That happens multiple times per shift."
— Modular Manufacturing Facility, Florida
If that happens four times a shift:
= 40+ minutes a shift gone at that one station
= and every minute of it invisible to your reports
📻 The call gets made and nobody hears it Daily misses
"It's a loud facility. Radios aren't heard well. Intercom calls aren't audible. We've tried everything."
— Foam Manufacturing, 60K sq ft, Pennsylvania
And where it’s quiet enough to hear, the call still has to reach that far:
"I didn't hear it. I was in the back near the compressors. The radio doesn't reach back there." — Maintenance Tech
The call was made. Nothing delivered it, and nothing recorded that it went unanswered.
🔔 Calls sit unanswered until somebody notices 25 min waiting
"The call was made 25 minutes ago. No one responded. The operator just sat there waiting."
— Tier-1 Automotive, Michigan
Without escalation:
• First responder is busy → call dies
• No backup gets notified
• No timeout rules trigger
• No one knows it's still waiting
📊 No proof of any of it when management asks Invisible losses
"I know we're losing time, but I can't prove it. When leadership asks how much downtime costs us, I have nothing to show them."
— Operations Manager, Midwest Manufacturing
"With radios there's no record keeping. It's all he said, she said." — Manufacturing Facility, Mississippi
• Can't prove which stations need the most help
• Can't show leadership what slow response actually costs
• Can't defend your team when something goes wrong
• Can't feed your CI reviews with real numbers
The idle time costing you every shift is invisible today

Now put your own numbers in
Five days a week, year round. This is exposure, not savings. It's time you're already losing. Nothing on your floor is timing these calls today, which is the actual problem.
Everything above is still an estimate. Run the free 60-day trial in your plant and you get the real number instead: every call timed, your own hours, station by station and shift by shift.
Your whole plant on one board
Every station on one board, under the names your plant already uses, with a clock running on every open call. Watch where the calls come from: some an operator pressed, some came straight off a machine, some from software you already run.
The board runs in a browser, so the same one opens on as many screens as you want, all at once and all in sync. Put it over the line, on the supervisor’s desk and in the maintenance office off any TV, monitor or PC you already own.
Someone presses a button
A call button sticks to the station, no wiring and no drilling. Up to five teams per station, labeled in your plant’s own words, so the call says who is needed before anyone walks over.
The machine calls on its own
A dry-contact module wires to a signal your equipment already produces and turns it into a call. Nothing inside the control panel changes, and there is nothing to program on the machine.
A system you already run
Your MES, SCADA, CMMS or a scheduled script calls an address on the computer running the software, and the alert goes out. If your system can flag it, we can page someone about it.
Nothing you own today is timing that wait
You already have radios, lights and an MES, and each one does part of the job well. None of them tells you how long your operator actually waited for help, or makes sure the call gets answered at all.

What’s in the system
Every system needs the transmitter and the license. The buttons and the pagers are how most plants put it together, sized to your floor and your crew. No new server, no cabling contractor, no license to renew.
What most plants start with
recommended
Call buttons at the station
They stick where people stand, so nothing gets wired and nothing gets drilled. Each button carries up to five teams, printed with your own names for them and assigned before it ships. Press one and it lights up, so the operator knows the call went out.
Specifications
| Radio | 433.500 MHz |
|---|---|
| Range to transmitter | 260 ft clear · plan 100–150 ft |
| Battery | 2 × AAA, up to 10,000 calls |
| Teams per unit | up to 5 |
| Mounting | adhesive, no wiring |
| Enclosure | water resistant |
Reaching the far end of the floor
Past roughly 150 ft, or through enough concrete and racking, a signal repeater sits between the call buttons and the transmitter. Every system ships with at least one, and a big floor chains several. We size them off your layout.
| Relays | up to 1/4 mile |
|---|---|
| Chaining | as many as the floor needs |
| Power | wall outlet |
Watch pagers and beepers
The alert lands on the person, not on a wall they have to be looking at. It vibrates silently and the screen names the station and what is needed. Same pager in two shells. A watch for people who will wear one, a clip-on beeper for people who won’t. They cost the same, so you can mix them across a shift.
Specifications
| Receives | 462.750 MHz |
|---|---|
| Battery | 3–4 days per charge |
| Recharge | 4 hours · one charger does 5 at once |
| Alert | vibrate + on-screen text |
| Watch | 100% waterproof · 1.5 × 5 × 0.5 in |
| Beeper | water resistant · 1.5 × 2 × 1 in |
The software license
Runs on one PC in your plant. The live board opens in a browser on any TV, monitor or PC you already own, and every call is timed and logged.
Specifications
| Host | one Windows PC runs the software |
|---|---|
| Transmitter | plugs into that same PC by USB, or onto your network by Ethernet |
| Data | stored on that PC, no cloud |
| Board | any TV or PC on your network, in a browser |
The transmitter
Every press reaches it first, then it drives the watches, the board and the lights. One reaches up to 3/4 of a mile and carries as many call buttons and pagers as you need, which is why you buy it once and everything you add after it costs a fraction of that.
Specifications
| Receives from buttons | 433.500 MHz |

Machine integration
A dry-contact module so the equipment triggers its own call the moment it faults or stops, without waiting for anyone to notice. Nothing inside the control panel changes.
Virtual buttons
The same call triggered from a computer, tablet or phone, with a custom issue list and a note. For when the right person needs to arrive already knowing what is wrong.
Your plant, from your phone
The alert lands on the lock screen. Open it and you have the floor plan, every call still open with its own clock, who has each one, and the same reports the office PC has. Tap Take and the call is yours, whether you’re in the office, in another building, or home on a Sunday. Plain texts and email are still there for anyone who prefers them.
About range. Every figure above is line-of-sight. Concrete, racking and metal cut all of it down, so real range depends on your building rather than the number. That is why a button rated at 260 ft is planned at 100 to 150 ft once walls are in the way. It is also why every system ships with at least one signal repeater, and why a big or spread-out floor chains several, each relaying about 1/4 mile. How many yours takes comes off your layout, worked out before anything ships rather than found as a dead zone later.
Most of the waiting sits on a short list you can’t guess
Below is one report out of a 27-station plant, cut two of the ways you can cut it. It tells the same story both times, and it isn’t the story anyone there would have told you from memory.
Every hour in both charts is somebody standing at a machine before help showed up. None of it is repair time. That is the half you can cut without getting any faster at the fix, and it's the half no downtime report on your floor separates out today.
Why people were waiting
% of all waiting timeWhich kind of help was slowest to arrive.
The calls at the top aren’t the most common failures. They’re the ones people wait on longest, which makes this a coverage and routing question rather than a repair one.
Where people were waiting
% of all waiting timeWhich stations lost the most time before anyone came.
The quickest way to move those six is arrival time: change who covers that end of the floor. Cutting the calls themselves takes longer, through a PM schedule change or a spare kept on the shelf.
Your top three won’t be these three. What lands on your list depends on your layout, your shift pattern and who covers what, and none of that shows up until the calls are timed.
The cuts you can pull
By station, by shift, by team, or by what the call was for. Compare one month against the last, so a change you made shows up as a number rather than an impression.
Waiting is a dispatch problem you can fix this month
All of the waiting above is time your maintenance team never had a chance at, so this reads as a map of how calls travel rather than a scorecard on your crew. Repair time takes longer to move, because that’s parts and skills. One number hides the difference; two show it.
Clean numbers you can export
A minimum-time rule drops accidental presses, and you can hide test calls. Export to CSV or PDF for a morning meeting, or stream it live into your BI or OEE system.
Try it in your plant, free for 60 days
You run it live on a real line for two months, on your floor, with your own people. We ship the hardware at no cost, and it goes back free if you don’t keep it. Six steps in total, and the first one is a phone call.
Agree to it
One call, one document, nothing to prepare
- Whenever you are ready
A 30-minute call about your floor
Which line, roughly how many call points, and what’s in the way on that floor. A trial is usually about ten call points on one line. That’s the whole call.
- Same week
One trial request to sign
It covers the equipment for the 60 days it’s in your plant. No invoice and no payment details.
Set it up
We configure it, you place it in under an hour
- Before it ships
A short form tells us how your floor works
Machine names, who each call goes to, when it escalates, and where any lights go.
- The day it lands
It arrives already configured and goes live
Stick the buttons on, hand out the watches, and brief the shift in five minutes.
Let it prove itself
Nothing to do but read it
- 48 hours in
Your own numbers start coming back
Your busiest stations and your longest waits, ranked, from two days of real shifts.
- Day 60
You decide on numbers from your own floor
Keep it and the price you already have covers exactly what you’ve been running, or it ships back free and your floor is exactly the way it was.
That’s phase one. Thirty minutes on the phone, and you’ll know if it fits your floor.
Trusted on 1,000+ plant floors
Tier-1 automotive, aerospace, packaging, chemicals, heavy equipment. Different products, the same problem with people waiting on help. Here are a few of them.
















































Real results from real plants
Different industries, same pattern: hidden idle time exposed within the first few shifts, and a wait-time number the plant had never had before.
Hidden Idle Time at a 24/7 Casting Plant
75+ production lines across multiple buildings. Operators used PA systems to call for maintenance — but nobody tracked when help arrived or how long the fix took.
200+ Stations Connected Across 2.1M Sq Ft
Workers walked to find supervisors across a massive facility. No call tracking, no escalation, and no Wi-Fi available for digital tools.
Andon Deployed Across FDA Clean Rooms
Clean room constraints, RF interference concerns, and corporate IT security requirements. Passed formal risk assessment without touching the corporate network.
7 more, same pattern in a different industry:
The questions every plant manager asks first
You will, and it’s two different approvals worth separating. Running the trial takes your operations lead, plus IT for the one PC the software sits on. No money moves and there’s no capital request. Buying takes finance and procurement, and that’s the harder one. Doing them in that order is the whole point: the capital request then arrives with sixty days of wait times measured on your own floor attached to it, rather than a number from us.
The waiting is already happening and it doesn’t pause for a budget year, so the question is how soon you can start rather than which line item it fits. The trial costs nothing in any budget year, and it’s what turns “we think we’re losing time” into a figure a request can be built on. When you do buy, we can split the payment or take a card if a PO cycle is the thing in the way. And if the whole plant is out of reach this year, one line is a far smaller number, and the transmitter and software in it already carry every line you add later.
Run us in parallel with whatever else you’re weighing. You can put ours on a real line for two months before anyone signs anything, so you settle it on your own logged response times instead of three sets of vendor claims. Ask the other two whether they'll do that.
You reconfigure it yourself. Rename the buttons, move people between teams, change the escalation times, all in the software. The buttons peel off and go back up somewhere else because nothing is wired. No new hardware, no rewiring, no service call, so a layout change costs you an afternoon rather than another purchase order.
Most reviews end at the first answer, which is that it doesn't touch your network. The radio is ours, the database is local, and there's nothing for you to host. An FDA-regulated plant cleared exactly this through a formal corporate IT risk assessment.
The answers IT will ask for
| Network needed | none at all for buttons, pagers and lights |
|---|---|
| Radio | dedicated 433.5 / 462.75 MHz, not Wi-Fi and not Bluetooth |
| If the network goes down | buttons, pagers and lights keep working |
| Cloud | none. The database is local to that PC |
| Host | one Windows PC, Windows only |
| Transmitter | USB to that PC, or Ethernet onto your network, so a virtual host is fine too |
| Traffic into the PC | one listening address, and only if you switch on calls from your MES or SCADA |
| Traffic out of the building | only if you run the plant from phones, or switch on text and email alerts |
You buy it once. No subscription, no per-user fees.
Three example builds at three sizes, here to show the shape rather than to price your plant. The only things that change between them are how many call points you cover and how many people carry a watch.
Transmitter, software license, call buttons and watch pagers.
Transmitter, software license, call buttons and watch pagers.
Transmitter, software license, call buttons and watch pagers.
A real system is rarely exactly one of these three. Repair-time buttons, floor lights, extra buildings and running it from phones all sit on top.
The transmitter and the software are the bulk of the first system, and you buy them once. That one transmitter already carries as many buttons and pagers as you need, so a second line is buttons and watches on top of what you already own.
What moves your number
- How many call points. One per machine, bench or cell where somebody would flag a problem.
- How many people carry a watch. Anyone who responds, so typically maintenance, quality, materials and supervisors.
- Whether you track repair time too. That needs a third button at the station, and it's what turns one number into two.
- How big and how obstructed the floor is. Concrete and metal cut radio range, so a big or spread-out building needs repeaters.
What to weigh it against
Whatever you spend here sits against the hours your people already spend waiting, and that is the one number almost no plant measures today. It's the comparison worth making, and the trial is what settles it.
None of this is a quote, and there’s no way to get one without talking first. One 30-minute call, a written price for the exact system you’d start with, then sixty days running it before you buy.
