Abstract

The present invention discloses improved smoke detector devices. In a preferred embodiment, the invention takes the form of an improved smoke detector of the type having a ceiling-mounted, main housing with an electrical circuit that includes an alarm device and a smoke sensing means that activates the alarm device when smoke is present in the vicinity of the sensing means. Wherein the improvement comprises a remote housing that is remotely disposed from the main housing, with the remote housing having affixed thereto a remote electrical circuit comprising a means for receiving an electrical connection from the main electrical circuit, a means for testing the operating condition of the main electrical circuit, a means for shutting off the alarm device, and a remote battery coupling means that allows a battery for powering the detector to be located in the remote housing. In another embodiment, the invention takes the form of a smoke detector remote unit, for use with a retrofitted, improved smoke detector, for providing the detector with remote testing, shutoff and powering capabilities.

Claims

1. An improved smoke detector of the type having a main housing and affixed thereto a main electrical circuit comprising an alarm device, and a means for detecting smoke that operates to activate the alarm device when smoke is present in the vicinity of the means for detecting smoke, wherein the improvement comprises:

a remote housing that is remotely disposed from said main housing,

a remote electrical circuit affixed to said remote housing and comprising a means for receiving an electrical connection with said main electrical circuit, a means for testing the operating condition of said main electrical circuit, a means for shutting off said alarm device, and a remote battery coupling means that allows a battery for powering the detector to be located in said remote housing, and

wherein said remote housing comprising a base configured so as to be mountable on the front of a recess-mounted, electrical box.

2. An improved smoke detector of the type having a main housing and affixed thereto a main electrical circuit comprising an alarm device, and a means for detecting smoke that operates to activate the alarm device when smoke is present in the vicinity of the means for detecting smoke, wherein the improvement comprises:

a remote housing that is remotely disposed from said main housing,

a remote electrical circuit affixed to said remote housing and comprising a means for receiving an electrical connection with said main electrical circuit, a means for testing the operating condition of said main electrical circuit, a means for shutting off said alarm device, and a remote battery coupling means that allows a battery for powering the detector to be located in said remote housing,

an electrical line that connects said remote electrical circuit by a quick-disconnect connector to said main electrical circuit, and

said type of detector to which said improvement applies further comprising a pin connector extending from said main electrical circuit for engaging with said quick-disconnect connector.

3. An improved smoke detector as recited in claim 2,

wherein said remote housing comprising a base configured so as to be mountable on the front of a recess-mounted, electrical box.

4. A smoke detector remote unit for use with a retrofitted and improved smoke detector so as to provide the detector with remote capabilities, the improved smoke detector being of the type having a main housing and affixed thereto a main electrical circuit comprising an alarm device, a means for detecting smoke that operates to activate the alarm device when smoke is present in the vicinity of the means for detecting smoke, a means for testing the operating condition of the main electrical circuit, a battery coupling means that allows a battery for powering the detector to be located in said main housing, and retrofit improvements comprising a test connector which allows a parallel electrical connection to be made across said testing means and a power connector which allows a parallel electrical connection to be made across said battery coupling means wherein the remote unit comprises:

a remote housing,

a remote electrical circuit affixed to said remote housing and comprising a means for receiving an electrical connection with said main electrical circuit, a testing contact that allows one to activate said means for testing the operating condition of said main electrical circuit, a means for shutting off said alarm device, and a remote battery coupling means that allows a battery for powering the detector to be located in said remote housing,

an electrical line that connects said remote electrical circuit by a quick-disconnect connector to said main electrical circuit, and

the retrofitted and improved smoke detector further comprising a pin connector extending from said test connector and power connector of said main electrical circuit for engagement with said quick-disconnect connector.

5. A smoke detector remote unit as recited in claim 4,

wherein said remote housing comprising a base configured so as to be mountable on the front of a recess-mounted, electrical box.

6. A smoke detector remote unit for use with a retrofitted and improved smoke detector so as to provide the detector with remote capabilities, the improved smoke detector being of the type having a main housing and affixed thereto a main electrical circuit comprising an alarm device, a means for detecting smoke that operates to activate the alarm device when smoke is present in the vicinity of the means for detecting smoke, a means for testing the operating condition of the main electrical circuit, a battery coupling means that allows a battery for powering the detector to be located in said main housing, and retrofit improvements comprising a test connector which allows a parallel electrical connection to be made across said testing means and a power connector which allows a parallel electrical connection to be made across said battery coupling means, wherein the remote unit comprises:
