Abstract
An electrical unit, such as a fire or gas detector, carries a three conductor plug for receipt of energy, AC hot, and neutral, as well as for coupling to a bidirectional signaling line. A multiple conductor adapter makes it possible to couple the plug to a plurality of incompatible, previously installed sockets. The adapter can be fully contained in a single housing. Alternately, it can include a housing for some of the conductors with the remainder carried on a cable which extends from the housing.
Claims8
An adapter for coupling an existing connector of a multi-wire interconnect system to a different ambient condition detector than the one for which the existing connector was designed, the adapter comprising:
- a non-conductive housing which carries a first set of electrical conductors and a second set of electrical conductors wherein the number of the second set of conductors is the same as the number of the first set of conductors, wherein members of the first set exhibit an electro-mechanical plug-type profile for engagement with socket elements of the existing connector and wherein members of the second set exhibit an electro-mechanical socket-type profile for engagement with a second plug carried by the ambient condition detector wherein the existing connector and the second plug are incompatible and are not mutually engageable, wherein the first set of electrical conductors includes a plurality of rigid conducting prongs which extend axially from the housing and are engageable with the existing connector.
An adapter system for coupling an existing connector of a multi-wire detector interconnect cable having a least one power wire and one signaling wire to an incompatible plug of an ambient condition detector where the plug of the detector includes at least one power terminal and at least one signaling terminal, the system comprising:
- a plurality of adapters with each adapter having a non-conductive housing with first and second ends, with at least two socket-type contacts carried at the first end, configured to engage the power terminal and signaling terminal of the detector's plug;
- at least two plug-type contacts carried at the second end with the two plug-type contacts configured to engage an interconnect cable connector with one plug-type contact adapted to engage a power contact and the second pug-type contact adapted to engage a signaling contact, both contacts carried by the connector with the socket-type contacts carried on the first end substantially the same for all members of the plurality of the adapters, and, with the plug-type contacts, carried at the second end different for all members of the plurality of adapters.
