发明名称 Removable battery and alarm system
摘要 The present invention relates to a removable battery system for a smoke detector having a low battery detection circuitry and an audible alarm. The system includes a pair of battery receivers each adapted to receive a battery therein and being electrically coupled to the low battery detection circuitry and the audible alarm wherein at least one of the batteries provides constant power to the low battery detection circuitry and the audible alarm. The system further includes a cover that is selectively movable to provide access to the battery receivers and a locking mechanism coupled to the pair of battery receivers wherein upon failure of one of the batteries received in the pair of battery receivers that provides constant power to the low battery detection circuitry and the audible alarm, the low battery detection circuitry sounds the audible alarm and selectively activates the locking mechanism to prohibit movement of the cover.
