Abstract
Disclosed is an interconnected smoke detector system of one or more smoke detector(s) wired into a dedicated circuit with a single location housing a DC power backup source, such as a rechargeable DC battery. The DC power backup source may be replaceable or rechargeable with DC current from and AC-DC transformer, a photovoltaic cell, or other means. Electronic relays within the system provide a current to the dedicated circuit by selecting between the line-voltage alternating current source and the DC power backup.
Claims20
A interconnected smoke detector system comprising:
- a smoke detector electrically coupled to a dedicated circuit;
- an alternating current source;
- a first direct current source located remote from the smoke detector in a location of a building structure;
- and
- a first relay electrically coupled to the dedicated circuit, the alternating current source, and the direct current source, wherein the first relay conducts a current to the dedicated circuit by selecting between the alternating current source and the direct current source.
A smoke detector comprising:
- A case enclosing an alternating current circuit, a direct current circuit, and a third relay;
- and
- an external current source, wherein the third relay determines whether the external current source is an alternating current or a direct current and routes the current source to the alternating current circuit or the direct current circuit of the smoke detector accordingly.
A method of forming a smoke detector system comprising:
- installing a smoke detector in a building;
- and
- electrically coupling a first relay to an alternating current source, a first direct current source, and the smoke detector, wherein the first relay conducts a current to the smoke detector by selecting between the alternating current source and the direct current source.
