Removable battery and alarm system
First Claim
1. A removable battery system having a low battery detection circuitry and an audible alarm, said system comprising:
- a first battery receiver and a second battery receiver, each of the first and second battery receivers adapted to receive a battery therein and being electrically coupled to the low battery detection circuitry and the audible alarm, at least one of the batteries received in the first and second battery receivers providing constant power to the low battery detection circuitry and the audible alarm;
a cover being selectively movable to provide access to the first and second battery receivers; and
a locking mechanism coupled to the first and second battery receivers;
wherein upon failure of one of the batteries received in the first and second 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 of the receiver containing a working battery until said failed battery is replaced.

Abstract
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.

13. A removable battery system having a low battery detection circuitry and an audible alarm, said removable battery system comprising:
-
a housing; a pair of battery receivers coupled to the housing, each of the battery receivers being adapted to receive a battery therein and being electrically coupled to the low battery detection circuitry and the audible alarm to provide constant power thereto; a cover slidably coupled to the housing, said cover being selectively movable between the pair of battery receivers; and a locking mechanism coupled to pair of battery receivers; wherein upon failure of the battery received in one of the battery receivers the low battery detection circuitry sounds the audible alarm and selectively activates the locking mechanism to prohibit movement of the cover of the receiver containing a working battery until said failed battery is replaced. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A removable battery system for a smoke detector having a low battery detection circuitry and an audible alarm, said removable battery system comprising:
-
a housing; a first battery receiver and a second battery receiver, each of the first and second battery receivers adapted to receive a battery therein and being electrically coupled to the low battery detection circuitry and the audible alarm, at least one of the batteries received in the first and second battery receivers providing constant power to the low battery detection circuitry and the audible alarm; a cover being selectively movable to provide access to the first and second battery receivers; and a locking mechanism coupled to the first and second battery receivers and including .an armature; wherein upon failure of one of the batteries received in the first and second 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 moves the armature of the locking mechanism to prohibit movement of the cover of the receiver containing a working battery until said failed battery is replaced. - View Dependent Claims (26, 27)
