Abstract
A security apparatus and method for protecting merchandise items is presented. In the preferred embodiment, a merchandise security device includes a housing with an access door that has an open position and a closed position, a primary power source, a secondary power source and alarm system. The alarm system determines when a voltage of the primary power source drops below a threshold value. When the voltage drops below the threshold value, the alarm system switches to the secondary power source for its power. When the alarm system is in a standby mode, it will not generate alarms when operating on the secondary power source. However, when the alarm system has not been placed into a standby mode, the alarm system will generate alarms when operating on the secondary power source and the access door is in the open position.
