Embodiment Construction

[0051] figure 1 A schematic diagram of a hazard indicator 120 is shown, which has a converter device 160 which can be connected via a connection 130 to a two-pole indicator circuit, not shown. According to the exemplary embodiment shown here, the transducer device is a hazard warning device, such as a fire detector, smoke detector, temperature detector, odor detector and / or chemical detector. However, the converter device can also be an actuator that opens or closes a door in hazardous situations, for example. In addition, the converter device 160 has an electronic module 150 through which the alarm circuit transmits electrical energy to the converter device 160 and / or the electronic module 150 is used for switching between the converter device 160 and the figure 1 The communication takes place between the central unit, also not shown in the figure.

[0052] The interface 130 has three input terminals, namely a first input terminal X1, a second input terminal X2 and a third ...

Abstract

The invention describes an interface (130) for connecting a converter apparatus (160) to a two-pole line. The interface (130) has three inputs (X1, X2, X3), a first output (A1) which is connected to a first input (X1), and a second output (A2) which can be connected to a second input (X2) or to the third input (X3). The interface (130) also comprises a switching device (132) which is connected to the second input (X2), the third input (X3) and the second output (A2), and a control device (134) which is coupled to the third input (X3) in such a way that a detection signal (DirSense) can be fed from the third input (X3) to the control device (132). This is indicative of whether the second input (X2) or the third input (X3) is connected to the second pole of the two-pole line. The control device (134) is designed in such a way that the second input (X2) or alternatively the third input (X3) is connected to the second output (A2) based on the detection signal (DirSense).

Description

technical field [0001] The invention relates to the technical field of electrical circuit technology or electronic circuit technology. The invention relates in particular to an interface for connecting a converter device to a two-pole line, wherein the first pole has a high potential and the second pole has a low potential. Furthermore, the invention also relates to a converter system and a converter device using said interface for connecting converter devices. Background technique [0002] In Europe, in automatic fire alarm technology, by standards and installation guidelines in many applications it is necessary to protect the fire alarm line to avoid complete breakdown due to short circuit. Currently, this requirement is ensured either by additionally providing short-circuit disconnection elements at specific positions in the fire line in addition to the existing sensors and actuators or by integrating short-circuit isolators and ring circuit structures in each sensor or ...
