The Cardiac Science 50-00395-20 semi-recessed wall box is designed for quick access to life-saving equipment during cardiac emergencies. Made of durable metal, it ensures the AED is easily retrievable and prominently marked. The cabinet features an audible alarm triggered upon opening, alerting facility occupants to a rescue in progress. Powered by a 9V battery for easy installation, it includes a low battery indicator. This semi-recessed cabinet requires a wall cutout, protruding slightly to maintain visibility without consuming excessive space compared to surface-mount cabinets. Its purpose is to ensure Cardiac Science AEDs remain visible, accessible, and ready for immediate use, recognizing the critical importance of time in cardiac emergencies.
