The Cardiac Science Semi-Recessed AED Cabinet with Alarm and Strobe Light (MPN 50-00395-30) is the corridor-friendly alarmed cabinet in the Cardiac Science Powerheart family. Built from rugged metal with a baked-on finish, the cabinet pairs a door-activated audible alarm with a high-visibility flashing strobe light — and recesses into the wall so only 3.12 inches protrude into your hallway.
Semi-recessed installation means the cabinet's back box sits inside the wall cavity while the perimeter trim overlaps the wall surface. The result is a cleaner architectural appearance than surface-mount cabinets, with significantly less protrusion into walkways — important for ADA compliance in narrow corridors, schools, hotels, and healthcare facilities where the 4-inch protrusion rule matters. A standard 2x4 stud wall provides sufficient cavity depth for the back box.
Like the surface-mount variant, this cabinet is security-enabled: the alarm can be hard-wired into your building's existing security system so the door-open event triggers a notification at your security desk or monitoring station. The keyed switch on the alarm assembly lets authorized staff disable the alarm for scheduled maintenance, training drills, or pad replacement without setting off the building system.
The 50-00395-30 cabinet is designed for the Cardiac Science Powerheart AED line. The integrated hook system accommodates both the G3 and G5 with or without their soft carry cases.
The cabinet has two integrated hooks inside. The Powerheart G3 hangs on both hooks for two-point support recommended configuration. The G5 hangs on a single hook designed for its handle geometry. Hooks keep the AED stable inside the cabinet so it doesn't shift during transport or accidental door bumps.
Cardiac Science offers the same alarm + strobe cabinet body in three mount styles. The right choice depends on whether your wall allows a cutout, how much hallway protrusion you can accept, and the visual look you want.
Semi-recessed installation requires cutting a rough opening in the wall sized for the cabinet's back box. The cabinet's perimeter trim overlaps the wall surface while the box itself sits inside the wall cavity. Before cutting, confirm the wall has clear space behind it no electrical, plumbing, HVAC, or structural framing in the planned opening.
Always confirm the exact rough-opening size from the installation diagram supplied with the cabinet before cutting drywall. Standard 2x4 stud wall construction (3.5-inch nominal stud depth) provides sufficient cavity depth for the back box.
The alarm assembly includes terminals for hard-wiring into a building's security system. This connection routes the door-open event to your central monitoring station or security panel, so staff are notified the moment the cabinet opens not just people within earshot. Wiring is a job for a qualified security technician or facilities electrician; check the alarm assembly instructions for terminal layout and supported relay types.
U.S. state laws on AED placement, signage, and registration vary. The Cardiac Science Semi-Recessed AED Cabinet meets equipment-side requirements for alarmed, publicly visible AED storage in every state. Where you mount it, how you register it, and how you log inspections is governed by your state. Higher-regulation states are summarized below.
AED registration with local EMS required. Monthly readiness checks must be logged. Signage and AED location notification to building occupants required (Health & Safety Code §1797.196).
AED owners must register with the regional EMS council. Health care facilities and public schools have additional signage and training requirements (Public Health Law §3000-b).
AED owners must notify the local EMS agency of each AED's location. Regular maintenance and physician oversight required (Health & Safety Code §779).
Physical Fitness Facility Medical Emergency Preparedness Act requires AEDs in fitness facilities with trained staff. Public schools (K-12) require AEDs on premises.
AED owners encouraged to register with local EMS. State schools and public buildings have specific placement and training requirements (F.S. §768.1325).
Cardiac Arrest Survival Act provides Good Samaritan protection nationwide. OSHA recommends AED placement in workplaces where cardiac risk or response delay exists. FAA requires AEDs on most commercial aircraft.
