AED Wall Cabinet Storage with Alarm ----- AED Wall Cabinets are constructed of heavy-guage steel and tempered glass to protect HeartStart Defibrillators from theft, vandalism and the elements. The Basic AED Wall Cabinet with Alarm is equipped with an audible alarm and flashing light powered by two 9-volt batteries to attract attention, to mobilize assistance or deter theft. Opening the AED Wall Cabinet door activates the alarm. For locations where a siren is inappropriate, the audible alarm can be disabled. The Basic AED Cabinet mounts on the wall.
