Automated external defibrillator alarms

Automated external defibrillator alarms

Recently some campus members have reported that several automated external defibrillators (AEDs) across campus are creating an audible alarm, much like a smoke detector does when its battery is low. The audible “chirping” alarm is due to the AED’s battery getting low on charge. New batteries are on order, but there’s a nationwide back order on Cardiac Science replacement batteries. At this time the manufacturer cannot give us an estimated time of arrival. The AED batteries begin sending an alarm when they have 30 percent of their charge remaining, which means they are still useable with enough charge to last for months. So they will remain in their cabinets for use until new batteries are received and installed.
