ANDON Call System for Manufacturing
Stop problems
before they stop production
Andon 4.0 is a real-time escalation and response system for production issues. It replaces phone calls and guesswork with structured, role-based escalation — ensuring faster reactions, measurable response times, and stable line performance even under pressure.
In practice, plants achieve up to 30% less downtime not because machines break less, but because reactions are organized, ownership is clear, and escalation never depends on who happens to be on shift.
See how much you can save →Andon isn’t just another signal. It’s a reaction system.
Andon 4.0 isn’t just another screen or reporting tool. It’s an operational reaction system that takes over coordination the moment something deviates from standard.
When a breakdown, material shortage, or quality issue appears, Andon automatically запускаes the right escalation path — no phone calls, no running around the floor, no guessing who should respond.
- One tap from the shop floor triggers action instead of communication chaos.
- Automatic escalation routes the issue to the right role within a defined time.
- Full status visibility — everyone knows who is responding and how long it takes.
- Data instead of opinions — recurring problems don’t disappear in shift reports.
The result? Less downtime, less improvisation, and production that doesn’t depend on who happens to be on shift.
How Andon reduces downtime and stabilizes production in real life
Downtime rarely comes from the breakdown itself. Most of the time, the real problem is delayed response, communication chaos, and unclear ownership. Andon 4.0 organizes that critical moment — before minutes turn into real losses.
The problem is visible instantly
Line events are captured in real time — no manual reporting, no running around, no hunting for information.
The alert goes to the right person
The system automatically routes the alert to the right role: maintenance, shift leader, quality, or logistics — no phone calls, no guessing.
Leaders see the situation without leaving their desk
Ticket status and response times are visible live — no end-of-shift reports and no “what just happened” explanations.
Every downtime has an owner
Downtime stops being “someone’s problem.” It has a defined owner, a response time, and a full history for future analysis.
The result? Faster response times, less loss, and production that stops running in constant firefighting mode. In practice, plants achieve up to a 30% reduction in downtime.
What results does Andon deliver in a real factory?
Companies that have implemented Andon 4.0 start seeing measurable benefits within the first weeks. Faster response times, less downtime, and better communication translate directly into higher profit and operational stability.

That’s why hundreds of factories choose Signalo — because we don’t sell software, we solve real operational problems.
How escalation works in Andon 4.0
– from signal to decision
Andon 4.0 structures the response to production problems. Every report from the shop floor запускаes a defined escalation path, so decisions happen fast and ownership is always clear.
-
01 Signal from the shop floorAn operator reports a problem directly from a tablet — a breakdown, missing material, quality deviation, or any other standard violation.
-
02 Automatic escalationThe system instantly routes the alert to the right role (maintenance, quality, logistics, shift leader), based on predefined rules and response-time thresholds.
-
03 Response & ownershipIt’s always clear who is responding and within what time. If no one reacts — Andon escalates further, instead of “waiting until someone notices the problem.”
-
04 Decision trail & dataEvery event is logged in the system: time of report, response, and resolution. That way recurring issues don’t disappear into shift reports.
As a result, problem response stops being improvisation, and production gains predictability — even when people or workload change.

Andon 4.0 – a real-time production issue response system
Andon 4.0 is not just another problem-reporting tool. It is a mobile response center that organizes escalation, shortens downtime, and takes decision pressure off people on the shop floor.
In practice, Andon 4.0 turns every production tablet into a trigger point for a clearly defined response. No phone calls, no running around, no guessing who should react.
Any deviation from standard is recorded and routed to the right role — without delays or misunderstandings.
An operator reports a breakdown, material shortage, or quality issue without calling or hunting for “the right person.”
The system decides who takes ownership — and escalates further if no one reacts on time.
Every event is logged: report time, response time, and resolution time. This becomes the foundation for real process improvement — not just after-the-fact reports.
The result?
Less firefighting, shorter downtime,
and production that runs predictably
— even when people or workloads change.
Control. Calm. Predictability.
Andon 4.0 gives you real control over what’s happening on the shop floor. No running around, no phone calls, no guessing whether someone is already reacting — or even knows about the problem.
In practice, Andon 4.0 organizes your plant’s day-to-day operations. Every problem reported from the shop floor is routed exactly where it should go — and you get a clear picture of what’s happening, without waiting for the end of the shift.
Messages, roles, and procedures are configured for your specific lines, workstations, and real-world problems — not a generic template.
An operator reports an issue with a single tap on a tablet, instead of calling, looking for a supervisor, or waiting until someone notices the downtime.
Notifications (SMS, email, app) reach the right people — maintenance, quality, logistics, or shift leaders.
Tablets and the interface are designed to work in dust, noise, and environments with high employee turnover.
Every event is logged in the system — so you can see where you’re really losing time, not just where it “feels like” something isn’t working.
Impact for leaders:
less firefighting during the day,
faster reactions to real problems,
and production that runs more smoothly — even when people and plans change.
Less chaos. Faster response. Full control.
One place where all shop floor issues are visible and controlled — in real time.
Andon 4.0 organizes how production issues are handled.
Instead of phone calls, running around the shop floor,
and guessing who is already reacting —
you get a clear signal of who took ownership, when, and with what result.
As a result, downtime is shorter, communication is simpler,
and decisions are made faster — even when people or production plans change.
The system works by your rules: lines, roles, issue types, and response times are configured for how your plant really operates — not for a generic template.
On a tablet at the machine, on a shift leader’s computer, or in the production office — without waiting for an end-of-shift report.
A multilingual interface ensures every employee knows what they are reporting and what happens next — even in international teams.
You see response times, downtime sources, and recurring issues — without manual data collection or guessing in meetings.
The system automatically routes each report to the right team and enforces response — instead of relying on memory and goodwill.
How daily operations change
Stable production doesn’t come from technology. It comes from clear, structured reactions to problems.
More real production time
Faster response reduces downtime and stabilizes line rhythm, instead of catching up at the end of the shift.
One communication standard across the plant
Everyone knows what to report and what happens next — without phone calls, guesswork, or manual coordination.
Better use of resources
People and machines are directed to where real value is actually created.
Fewer operational losses
Problems are caught early, before they turn into downtime, scrap, and overtime.
Full visibility of plan execution
Leaders react during the shift, not only after reviewing reports.
More control, less stress
Clear response rules increase safety and take decision pressure off people.
How it works
In critical moments, when every second matters.
Changeovers without delays
The system triggers support exactly when it’s needed, reducing downtime between production runs.
Immediate failure response
When a line stops, the right team is notified instantly — no calls, no searching for contacts.
Just-in-time deliveries
One click submits a request. Logistics responds without unnecessary conversations.
Staffing gaps under control
Missing an operator? The system flags the issue before it impacts plan execution.
Faster quality inspections
Finished products are automatically routed to inspection without blocking the production line.
Instant plan changes
When priorities change, the team gets a clear signal. Production adapts without chaos.
Where the gap forms between a signal and a reaction on the shop floor
Downtime doesn’t come from failures alone. It comes from delayed reactions, communication chaos, and unclear ownership. Andon 4.0 organizes this critical moment — exactly where production most often loses money.
React before the problem escalates
Events go instantly to the right people. No calls, no searching for a shift leader, no firefighting when losses are already irreversible.
Less downtime. Fewer losses.
Shorter response times mean real cost reduction: less line stoppage, less overtime, and more predictable plan execution.
Data instead of opinions
Every report is recorded. You know where time and money are really being lost — no guessing and no “I think so.”
A system tailored to your production
Andon 4.0 works by your rules, not generic templates. It scales with your plant and integrates with your existing IT environment.
One communication standard across the plant
Operators, maintenance, logistics, and shift leaders work in one consistent response process — regardless of language or shift.
More stable and safer production
Faster reactions reduce EHS risks, improve quality, and lower stress on the shop floor — day after day, shift after shift.

Frequently Asked Questions About the Andon System
In most factories, deployment takes from a few days to a few weeks. The system does not require long downtime — installation is modular and adapted to your existing infrastructure. After a short training, employees can start using the system immediately.
Yes. The system can operate both online and in local mode (LAN or GSM). In case of connectivity issues, data is temporarily stored locally and synchronized once the connection is restored, so no information is lost.
No. Andon 4.0 integrates with existing ERP, MES, and CMMS systems via open APIs, without the need to replace your infrastructure. Devices such as industrial tablets are designed to operate reliably in harsh factory-floor conditions.
The cost depends on the size of your plant and the number of workstations, but thanks to a subscription model it does not require large CAPEX. In most cases, ROI appears within the first few months, mainly due to reduced downtime and production losses.
Factories using Andon 4.0 typically report 25–40% less downtime, faster reaction to failures, and smoother operations. In addition, communication becomes more transparent and team effectiveness improves, which translates into real cost savings.
Executive summary
Signalo Andon 4.0 — short and to the point
Andon 4.0 is an operational response system built by Signalo that detects and escalates production events in real time. Its goal is not “visibility” — but faster reaction, less downtime, and more stable production.
Issues are reported directly from tablets at workstations, and the system automatically routes alerts to the right roles (maintenance, shift leaders, quality, logistics). It runs without IT involvement and can integrate with ERP, MES, and CMMS.
Andon 4.0 works just as well in smaller plants as in large multi-shift factories. In practice, it delivers lower costs, better quality, and real control over production flow.
