  • Device for supplying electrical power to detectors, control devices and signaling devices
    Patent number: 6778371
    Abstract: A device for supplying electrical power to detectors, control systems, and signaling systems is described, in which the power supply line can be implemented as a ring. Each of the peripheral consumers connected to the ring has a power supply device which connects through the power supply line to the next power supply device depending on a minimum voltage. Power supply terminals, which detect short-circuits and/or interruptions on the power supply ring and therefore the lack of power supply to a detector, are each connected to a ring input and a ring output. Alternatively, the power supply line may be implemented as a spur line, with power supply then provided up to an occurring short-circuit or an interruption. In the case of the spur line, the control center is informed in that it receives signals from the individual detectors about an existing power supply via an alarm line.
