Coolroom temperature monitoring & alarms

Your stock sleeps. We watch the temperature.

Continuous coolroom temperature monitoring with automatic HACCP logging, and an alarm that actually reaches you. The moment a coolroom or freezer drifts out of range it escalates: push, then SMS, then a phone call, until a real person answers. It keeps watching through a blackout, and hands you the records your council EHO wants.

Installed and monitored by an Australian team. A real person sets it up, and answers when something's not right.

The night it climbs

One number decides whether you open up to a full coolroom, or an empty one.

Scroll through the night a compressor quietly gives up. Watch the temperature, and watch what happens when someone is actually told.

11:00pm

Closed up, all good.

Coolroom 2 sits at 2.4°C, right where it should be. The last delivery is away, the door is shut, the room is holding. Nothing for anyone to do.

1:10am

The compressor stops.

No bang, no spark. It just quietly stops fighting. The room is still cold, so a simple threshold alarm says nothing yet. But the only direction the number can go now is up.

2:30am

5.1°C, and rising.

It crosses 5°C, into the danger zone, climbing on a steady curve. This is the moment everything turns on. A silent app badge would let it keep going. We don't.

2:31am

We call your phone.

Push, then SMS, then an actual phone call, to you, then the next person on the list, until someone answers. Hard to sleep through. Easy to act on.

Before 7am

You're back, stock saved.

You called the fridgie at 2:40am, propped the right door, moved what mattered. By open the room is back to 2.9°C and the bin run never happened. The call cost you a night's sleep, not a night's stock.

The other morning

14°C. Everything gone.

The morning nobody was told, the same failure ran for six hours. The night's prep, the produce, the meat: all of it in the bin, and no record to show why. That is the morning a real alarm exists to prevent.

The cost of one bad night

You find out the coolroom failed when you open up. Stock gone, no record, no warning.

A compressor fails at 2am, a door is left ajar after the last delivery, the power drops over a long weekend. By open, the damage is done, and a clipboard can't tell the EHO what happened.

One overnight failurea coolroom of stock

For a butcher or a busy cafe, a single warm-up event is thousands of dollars, a health risk, and a morning spent unpacking the loss instead of trading.

The overnight failure nobody hears.

A coolroom can warm up for hours before anyone notices. A silent notification on a phone that's face-down and on mute does not save your stock. The alarm has to reach a human and keep trying.

And the Wi-Fi monitor that should warn you goes blind in the exact blackout that kills the coolroom. The alarm that protects stock runs on battery and 4G, and climbs from push to SMS to a phone call until someone acts.

What you get

More than a thermometer. A system that protects your stock and your records.

We don't post you a sensor and a manual. We design it for your rooms, install it, and keep it monitored. You get the alarm and the audit trail.

The 2am wake-up that works

Push, then SMS, then a phone call, to multiple people, escalating until someone acknowledges it. Not a silent badge: an alarm that keeps trying until a human acts.

Keeps working in a blackout

Battery backup plus a 4G cellular link mean it keeps monitoring and alerting straight through a power or internet outage. You also get a power-failure alert in its own right.

HACCP-ready records, automatically

Every reading logged and kept, with reports the council EHO or your auditor actually asks for. It replaces the clipboard and the human error that comes with it.

Every room on one dashboard

Coolrooms, freezers and fridges in a single view, on phone, tablet or laptop, each with its own thresholds. One room or twenty, watched the same way.

Door-open & compressor-fail

A door left ajar or a compressor losing the fight shows up as a rising trend and a warning before the danger zone, not after the stock has warmed.

Installed & monitored

We fit it, no rewiring, no fridgie, no downtime to your coolroom. Then it stays monitored, so a flat sensor or a dropout gets sorted before it leaves you blind.

HACCP records, done for you

Replace the clipboard with records that hold up.

Standard 3.2.2A of the Australia New Zealand Food Standards Code asks you to substantiate that cold storage stays in control. Continuous logs do exactly that, instead of a paper sheet that gets back-filled.

A time-stamped record for every room, kept and ready to show on request. No clipboard, no gaps on a busy shift.

Cold potentially hazardous food belongs at 5°C or below; the danger zone runs 5°C to 60°C. We log every reading so you can show your control, not just claim it.

We help you demonstrate compliance; we don't certify it, that's for your council EHO and accredited auditors. Records stay available on request and are kept for the period your state requires.

Who it's for

If it holds chilled or frozen stock, we watch it.

Cafes Restaurants Pubs & clubs Butchers Fishmongers Florists Caterers Supermarkets Cold-storage

How it works

Three steps, then you stop opening up to spoiled stock.

We map your cold storage

Tell us your coolrooms, freezers and display fridges. We set the right temperature thresholds and who needs to be alarmed, in what order.

We install it

Sensors fitted in each room, the gateway stood up with battery and 4G backup, the dashboard set, your escalation list built. One visit, no downtime.

You get watched, and warned

Live temps on your phone, an alarm that reaches a human when a room drifts, and the HACCP-ready records ready whenever the EHO asks.

Backed by the people who install it

Built by a team that fits this gear, not a kit in a box.

Coolroom Alarm is run by Alien IT Solutions, with 15+ years building networks, sensors and connectivity that has to work when it counts. We're vendor-agnostic: we fit the right sensor for your rooms, not the one we're told to sell, and we bundle the install, the monitoring and the escalation that self-install kits leave to you. It's part of our wider temperature monitoring work across cold chain and food safety. Want the hardware only? You can buy the kit and run it yourself.

Questions people ask

The honest answers.

Will it actually wake me at 2am?

Yes, that's the whole point. The alarm escalates from a push notification to SMS to an actual phone call, to more than one person, and keeps going until someone acknowledges it. It is not a silent app badge you find in the morning.

What if the power or internet goes out?

It keeps watching. Battery backup runs the sensors and gateway, and a 4G cellular link gets the alert out even with your internet down. You also get a power-failure alert in its own right, which is often the first sign a coolroom is about to be in trouble.

Does this make me HACCP compliant or pass my council audit?

It produces HACCP-ready temperature logs and reports that help you demonstrate temperature control under Standard 3.2.2A and 3.2.2 of the Food Standards Code. We don't certify you or guarantee a pass, certification and audits are done by accredited bodies and your council EHO, but the records make your case easy to show.

Can it watch multiple coolrooms and freezers?

Yes. One dashboard covers every coolroom, freezer and display fridge, each with its own high and low thresholds. Coolrooms typically run 2°C to 4°C and freezers around minus 18°C or colder; you set what's right for each room.

Will it tell me if a door's left open or the compressor's failing?

Yes. A door left ajar or a compressor losing ground shows up as a rising trend and an early warning before the room reaches the danger zone, so you can act while the stock is still good.

How hard is it to install, do I need a fridgie?

No. We install it. It's non-invasive, nothing is rewired and there's no downtime to your coolroom. We fit the sensors, set the thresholds and build your alarm list in a single visit.

What does it cost, is it a subscription?

It's an upfront install plus a monitored plan, and we tell you both numbers plainly so there are no surprises. The monitored plan is what runs the escalation, the cellular link and the logging. Send us your rooms and we'll quote the real figure.
