Run status, mains-fail events and readiness of standby plant, so you know it will start when you need it.
4Warn · RF & GSM asset monitoring
Know the moment
Know the moment
something goes wrong.
4Warn watches your critical assets onsite — generators, cold rooms, server rooms, diesel tanks and more — relays the signal by RF to our servers, and raises the alarm by SMS, Telegram, email or pager the instant a reading breaches its limits.

What we monitor
One platform for every critical asset
If it has a temperature, a level, a voltage or a state we can watch, 4Warn can keep track of it — using RF or GSM units depending on what suits the site.
Server rooms
Temperature, humidity and power conditions in comms and server rooms — caught before hardware suffers.
Diesel & fuel tanks
Live fuel levels and drop alerts — spot theft, leaks or low reserves before they leave you stranded.
Fridges & cold rooms
Scheduled temperature logging with automatic weekly graphs — the audit trail you need to stay compliant.
Air conditioning
Supply-air temperature and run status — know the instant cooling fails in a critical space.
Relays & switching
Open/closed states and switching events for pumps, doors, alarms and any dry-contact signal.
BMS systems
Integrate with building management systems to surface faults and readings on one shared dashboard.
…and more
We monitor a wide variety of assets. If you can measure it, talk to us — chances are we can watch it.
How it works
Monitor. Transmit. Alarm.
A simple, reliable chain — from the equipment on your site, over RF to our servers, to the alarm in your hand.
01
Monitor onsite
Rugged units read temperature, level, voltage, run status and relay states directly on your assets, around the clock.
02
Transmit by RF
The signal is sent by Radio Frequency (RF) across our network to our servers — independent of the mobile carriers.
03
Raise the alarm
The moment a reading breaches its limits, our servers send the alarm by SMS, Telegram, email or pager — with full reporting available.
Using our GSM units? They log readings and plot them into graphs over time — and you can query a unit at any moment to pull the current onsite temperature.
Control-room systems
Alarm Monitoring Systems, built in-house
We design and build our own Alarm Monitoring Systems (AMS) and supply them to control rooms — the system operators sit in front of to receive, display and action alarms as they come in.
Rent it, or own it outright
Because we build the AMS ourselves, you choose how you take it on — and we support and adapt it either way, without waiting on a third-party vendor.

Who runs on it
-
Armed response companies
Signals from client sites land in the control room and get actioned by the operator on duty.
-
Mines
Plant and safety alarms across a large site, consolidated onto one control-room view.
-
Large industrial parks
Many tenants, many alarm points — monitored centrally instead of site by site.
Cold-chain compliance
Temperature compliance, handled.
Our GSM units log temperatures over time and plot them into clear graphs — like the real 7-day vaccine-fridge report shown here. Query a unit whenever you like to read the current onsite temperature, and lean on full reporting to stay compliant with health and food-safety regulations — without anyone writing down a single reading.
- Continuous temperature logging & graphing
- Query current onsite temps on demand
- High- and low-limit alarms via SMS, Telegram, email or pager
- Full reporting for auditors — built & supported in-house

Why 4Warn
Built to catch problems before they cost you
Our own RF network
Where our RF coverage reaches, you’re not dependent on a single mobile carrier — more resilience, fewer blind spots.
RF and GSM
Every site is different. We choose the connectivity that gives the most reliable link for each location.
In-house hardware
We design and build our own units — including the fridge temperature logger — so we can support and adapt them.
Compliance-ready reporting
Full reporting and temperature graphs give you an audit trail regulators accept, with no manual logbooks to keep.
Alarms, your way
SMS, Telegram, email or pager the moment something breaches its limits — so the right person acts, not a dashboard nobody watches.
Local support
A South African team that understands local conditions, load-shedding realities and your regulatory environment.
About us
Messaging Software Solutions
Messaging Software Solutions helps businesses protect their most important equipment through remote monitoring and timely alerting. Our 4Warn platform combines our own RF network, GSM connectivity and in-house hardware to watch a wide variety of assets — from generators and diesel tanks to cold rooms, server rooms, aircons, relays and BMS systems.
Alongside 4Warn we build our own Alarm Monitoring Systems (AMS) for control rooms, available to rent or buy outright, and already in use by armed response companies, mines and large industrial parks.
The principle is simple: the sooner you know about a problem, the cheaper and easier it is to fix. We turn quiet failures — a warming fridge, a generator that won’t start, a draining fuel tank — into an alert in your hand, and into the records you need to stay compliant.
