To help mobilize an emergency medical response or deter AED theft, Philips offers three different battery-operated, alarmed wall cabinets. The basic cabinet has a simple audible alarm. Also available are two premium cabinets: a wall surface mounted cabinet and a semi-recessed cabinet that is inserted into a wall cut-out for a less obtrusive look.* The premium cabinets feature combination audible and flashing light alarms. They are made of sturdy, heavy-gauge steel and are large enough to accommodate additional medical supplies, such as oxygen. You can also connect the premium cabinets’ alarms to your internal security system so that a more coordinated emergency response can be mobilized centrally.
