First Claim
Patent Images
1. An audible alarm system for an automated external defibrillator (AED), comprising:
- an alarm condition indicator designed to detect an alarm condition within the AED; and
an audible alarm circuit, operable on a power level of less than 5 volts from a power source wherein said power level is less than the operating power level of the alarm condition indicator from the power source, connected to said alarm condition indicator and designed to produce an audible alarm through an external audible alarm port, said audible alarm circuit initially activated by said alarm condition indicator, and wherein said audible alarm circuit operates independently of said alarm condition indicator after the initial activation.
