Compact Size AED Wall Cabinet with Advanced Alarm Options. This junior cabinet is perfectly sized for smaller AEDs like the Philips HeartStart Onsite. Just like larger cabinets, the sturdy metal construction protects and prominently displays your AED. Door-activated audible alarm alerts everyone in the area the AED has been deployed for rescue. The alarm has multiple settings to control the alarm function and duration and has the capability of being connected externally, for example connecting to a security station. The strobe light is ideal for noisy environments and also serves as an indicator showing the cabinet is alarmed, which serves to deter tampering.
