Abstract: Disclosed is a rechargeable battery 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.

Abstract: Disclosed is a battery interconnected detection and alert device system with building structure vibrational alert. The system includes of one or more alert devices 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 an AC-DC transformer-rectifier, a photovoltaic cell, or other means. An electrical relay within the system provides a current to the dedicated circuit by selecting between the line-voltage alternating current source and the DC power backup. When activated, the detection and alert device generates a distinctive pulsed vibrational alert transmitted through the building structure to beds and other furniture resting on the floor, and additionally transmitted through the air as pressure waves which are perceived by hearing-impaired and other persons alerting them to a possible emergency situation.

Abstract: Disclosed is an alarm device system with simultaneous AC/DC power. The system includes of one or more alert devices 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 an AC-DC transformer-rectifier, a photovoltaic cell, or other means. A dedicated circuit is energized with a composite current to provide continuous, uninterrupted DC backup power, upon which line AC is superimposed. AC and continuous DC backup are simultaneously provided to a system of detection and alert devices, such as smoke alarms, electrically coupled to the dedicated circuit.

Abstract: Disclosed is a battery interconnected illumination device and system. The system includes one or more illumination devices 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 an AC-DC transformer-rectifier, a photovoltaic cell, or other means. An electrical relay within the system provides a current to the dedicated circuit by selecting between the line-voltage alternating current source and the DC power backup. A light source of the illumination device is mounted on a mounting surface, such as a ceiling or building wall, by a mounting plate which forms a gap between the light source and the mounting surface. When activated, the light source shines light onto the mounting surface, illuminating the space with low-glare indirect reflected light.

Abstract: An AC powered and DC battery backup powered interconnected smoke alarm/detector system that provides battery backup to each and all smoke alarms/detectors within a dwelling using a single, centrally located rechargeable backup battery. Both AC power and DC backup power sources are distributed and provided to each and all smoke alarms/detectors through the same electrical high voltage wiring via an AC and DC Pass-Through Relay.

Abstract: A method and system for providing on-location troubleshooting services to homeowners and businesses for low-voltage electronic equipment and other on-location services. It employs the use of an Internet-based system for recording customer requests for service and subsequently automatically dispatching technicians and managing provision of the requested services. It also provides functions to support customer and technician recruitment and sign up. Additionally, it provides functions for recording customer satisfaction, requesting repair services and links to low-voltage electronics equipment suppliers for purchasing desired low-voltage electronics equipment. Service areas, work cells are established for groups of customers which are closely located geographically. Technicians are recruited and assigned responsibility for work cells based on whether their residence is in or close to a particular work cell or group of work cells.
