My AED is Chirping, What Does that Mean?


The room is quiet until suddenly you hear a chirping noise. You follow the sound and discover your AED is chirping. What does that mean? It is common for an AED to give a chirping sound when something needs attention or care. Don’t stress! This is one of the many amazing features these defibrillators have. With Philips AEDs, self-checking occurs daily to ensure that when an emergency occurs, you have the best possible resources ready. When your AED is chirping, it can mean more than one thing. At any time when your AED begins to chirp, press the information button and the AED will read what the problem is. The machine will tell you whether it is an issue with the pads, battery, software, or another more serious problem. Below are the different reasons and follow-up measures you should take when your AED begins to chirp!


Expired AED Pads


Each AED package will include a set of pads. When in use, the pads attach to the individual and will emit a shock when needed. Always remember to replace pads after each use, but when unused, the pads also have an expiry date. The defibrillator will know when the pads expire or have been open to air and have lost effectiveness (pertaining to the gel). If your AED is chirping and informs you that the pads have expired, it is important that you call and order new pads right away. The longer you wait and put off ordering them, the increased risk of someone not getting the attention they need in an emergency. To stay ahead of your AED, you can simply look at the expiration date located on the bottom of the pads and order yours before your AED chirps!


We also highly recommend purchasing a spare set so that when one is used you have a backup available for use right away.


AED Software Update Needed


Philips is constantly updating and developing new technology to ensure that our lives and hearts are saved in the most efficient and safe way possible, so it is not uncommon for an AED to need a software update. This could be something as simple as updating the phrasing of commands, or the timing between shocks. All software updates are there to ensure your AED is in prime condition and offering the best lifesaving technology should an emergency occur. As soon as you notice that your AED is chirping and it tells you that it needs a software update, acquire the update as soon as possible. For software updates, the best way to have this resolved is to call First Edition First Aid Training Inc. at 403-243-2644 and discuss how to go about getting your AED updated. Updates are there to make things run smoother and ensure that when an emergency happens, everything performs 100%.


Expired AED Battery


Although Philips AEDs will do self-checks daily, weekly, and monthly, the batteries will eventually expire. It is when this is about to happen that you will find your AED is chirping. Philips AEDs have a shelf life of 5 years, after that you will need to purchase a replacement. If the battery needs replacing, call and order your new battery right away. It is not safe to use an AED that has a low or expired battery, and therefore should receive attention immediately.


Other Reasons Your AED is Chirping


In some cases, there may be a problem with your AED that is not recognized in a command. Your AED will chirp but the relay of the issue may not be clear. Here are some of those possible incidents and how to approach them.


Mechanical error

Mechanical errors may occur if the AED became damaged either when previously used or if it was not stored properly. If the AED has a malfunction or does not inform you about a specific problem, call for immediate support and a professional will be able to assist you. Always call the company who originally sold you the machine.

AED Pads Not Plugged In

When storing the AED, the pads will need to be connected at all times. If somehow the pads became disconnected or were not plugged in when stored, you will find your AED is chirping to remind you of this easy fix.


AED Pad Cartridge

When your AED begins to chirp, and asks you to insert the pad cartridge, it may mean that there is damage to the cartridge. The pad cartridge is the part of the AED that contains the pads (pulled out in an emergency). In this instance, it requires a replacement and should be installed as soon as possible.



In any situation when your AED is chirping, attend to it right away. The Philips defibrillators function is to self-test and help remind you when things need a replacement or need fixing. Some issues are easily solved, but if you ever come across a more serious problem or are unsure how to proceed, contact First Edition First Aid Training Inc. and we can help! Stay safe, be prepared, and keep your AED in great working condition!
