An apparatus includes an AC-to-DC power supply, with a positive terminal operatively coupled to two two-wire pairs of an Ethernet port to provide a first and second power path over a structured cable. A negative terminal is operatively coupled to a third two-wire pair of the Ethernet port to complete the first power path. Power path control logic has an input port operative to receive a two-wire input signal from an external device, and is operatively coupled to the negative terminal of the AC-to-DC power supply output, and to a fourth two-wire pair of the Ethernet port to complete the second power path. The power path control logic is operative to disconnect the negative terminal of the AC-to-DC power supply from the fourth two-wire pair of the Ethernet port in response to a two-wire input signal received at the input port, to disconnect the second power path.

An electrical power line mounted fire warning system and a method of monitoring and providing a fire warning using the same are provided. An electrical power line mounted fire warning system includes: a plurality of sensor nodes, each including a housing mountable on an electrical power line, a plurality of sensors supported by the housing and including an IR sensor and/or a bolometer to detect a fire, and optionally including an electromagnetic sensor to detect at least one of a spark, a current surge of the electrical power line, or a line short of the electrical power line, a microcontroller configured to determine existence of a fire or a fire risk based on one or more parameters detected by the plurality of sensors, and a communication device.

To provide an auxiliary unit capable of reducing the number of signal lines for outputting warning information. A multi-output unit is connected to a plurality of sensor units via individual output lines 262a to 262h through which the plurality of sensor units output a detection result of each of the plurality of sensor units and a data line 261a for communicating with the plurality of sensor units. The communication control unit 104 communicates with each of the plurality of sensor units via the data line 261a and receives warning information transmitted by at least one of the plurality of sensor units. When receiving the warning information from at least one of the plurality of sensor units via the data line 261a, the common signal line 154 outputs a common output signal indicating the warning information to an external device.

Methods, systems, and products bridge wireless data transmissions with power-line communications. Should a failure occur in alternating current power, a backup battery maintains the power-line communications. Direct current battery power is used to power a wireless transceiver, thus maintaining both wireless data transmissions and communication during power failures.

A meter socket with a tamper detection assembly is disclosed. The tamper detection assembly may include a light sensor that enables the detection of tampering caused by an energy thief removing the cover of the meter socket enclosure and/or removing the meter from the meter socket in an effort to access the power supply connectors and steal electricity. The tamper detection assembly may also include an acoustic sensor that enables the detection of tampering caused by an energy thief drilling, cutting, hammering, bending or otherwise attempting to violate the integrity of the meter socket enclosure in an effort to access the power supply connectors and steal electricity. The tamper detection assembly is preferably mounted within a mounting block of the meter socket so as to provide a secure source of power and communications for the assembly.
