STI Defibrillator Theft Stopper, 5" W x 5" H x 2" D

MFG Part #:
Here is an effective way to help reduce the risk of theft. The Defibrillator Theft Stopper incorporates a unique steel cable operated switch mechanism. This allows the defibrillator to be used for a medical emergency, but it sounds a powerful alarm when the AED is removed. This loud alarm may alert your first responders in the building, but it can be very disturbing for a potential thief. Before use, the steel cable is permanently crimped around the handle of the AED. When removed from the unit, the alarm sounds. Reinserting the cable silences the alarm.
