Coolroom & freezer alarms · all of Australia
A coolroom alarm that wakes you before your stock spoils.
The moment a coolroom or freezer drifts out of range, it alarms: push, then SMS, then a phone call, escalating until a real person answers. It keeps watching through a blackout, and hands you the HACCP-ready temperature records your council EHO wants. We install it, it watches your stock, it raises the alarm, you get the records.
Installed and monitored by an Australian team. A real person sets it up, and answers when something's not right.
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.
! The overnight failure nobody hears
A coolroom can warm up for hours before anyone notices. By morning the night's prep, your produce and your meat are all in the bin, and you only find out unpacking it.
! An app badge nobody reads at 2am
A silent notification on a phone that's face-down and on mute does not save your stock. The alarm has to actually reach a human and keep trying.
! The clipboard the EHO doesn't trust
Handwritten temperature logs get back-filled, skipped on a busy shift, or lost. When an authorised officer asks for your records, "we usually check it" is not an answer.
! Wi-Fi monitors go blind in a blackout
The exact power or internet outage that kills the coolroom also kills a Wi-Fi-only sensor, so it stops watching at the worst possible moment.
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.
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: a time-stamped record for every room, kept and ready to show on request, instead of a paper sheet that gets back-filled.
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 logged this week, by room
Automatic and continuous, every room, kept for the record. No clipboard, no gaps on a busy shift.
How it works
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 stop opening up to spoiled stock
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 people who actually install this gear
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
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.
