A collection of parts designed to provide audible and visual alerts when a surface-mounted automated external defibrillator (AED) cabinet is opened. These kits commonly include a siren or buzzer, a flashing LED indicator, wiring, and mounting hardware. For instance, these components are integrated into a cabinet housing an AED in a public area like a school or office building.
The purpose of such a device is to deter theft or vandalism and to notify nearby individuals that the AED is being accessed, potentially signaling a medical emergency. This can improve response times by alerting trained personnel or first responders to the situation. Historically, the need for such systems arose from concerns about the security and availability of AEDs in public locations.
