pie chart showing that 70% of cardiac arrest deaths occur outside of hospital
Every year, approximately 5,000 people in Ireland die from cardiac arrest. Of these, 70% happen outside of hospital, which makes it critical to have public access to properly maintained life-saving equipment.


In 2015, the Health Products Regulatory Authority (HPRA) identified nearly 1,000 defibrillators in Ireland that could fail in an emergency because of outstanding maintenance issues. Normally, devices need to be regularly checked in person to ensure there are no maintenance alerts on the screen, which can be forgotten or leave the defibrillator out of order for a period of time before the next inspection.

The Challenge

• Provide an easy-to-install option
• Allow AEDs to be placed virtually anywhere
• Monitor the status of AEDs to provide timely maintenance
A Sigfox defibrillator cabinet, made by Pyres

Ireland’s first Sigfox-enabled defibrillator cabinet, seen here, was installed in DCU Alpha on Nov. 7, 2016.

The Solution

The AIVIA monitoring case, designed by Pyrescom, uses an optical sensor to view the AED screen, and send an alert as soon as there is a change in the status of the cabinet, rather than relying on in-person visual checks

Pyrescom and other companies also make cabinets that communicate via wifi or cellular connectivity. Cellular is more expensive, and both options mean that the cases have to have hardwired electricity because of the energy requirements of those connectivity options. An electrician was required for the installation process.

With the introduction of low-power, affordable Sigfox connectivity, Pyrescom was able to switch indoor cabinets to battery power, which lasts about three years. Installation is now a simple matter of mounting the unit on the wall, with no need for professional help. The cabinet has its own power and doesn’t feed off the battery of the AED itself, ensuring the device is always ready for a life-threatening emergency. If there are any maintenance or battery notifications on the screen, the cabinet will immediately send an alert. It also sends a notification about the status of its own battery once per week.

In Ireland, the distributor for AIVIA cabinets is Heartsafety Solutions.

Why Sigfox?


Sigfox is the most affordable way to connect low-bandwidth devices, which allows wide-scale rollouts. Early defibrillation can more than double a person’s chance of surviving a cardiac arrest. This makes wide availability of AEDs important.

Low Power

Sigfox connectivity is extremely energy efficient, which allowed Pyrescom to produce a connect AED cabinet that is battery operated. This means there is no complicated mains wiring, and also allows the AEDs and cabinets to be placed anywhere.


Sigfox-connected AED cabinets are an easy, affordable way to ensure defibrillators are properly monitored and functioning in the event of a life-threatening emergency. Battery powered cases also allow AEDs to be installed virtually anywhere. There are more than 150,000 AIVIA cabinets worldwide.
