Description

The invention relates to a danger alarm center and a method for commissioning and configuration of a danger alarm center.

Danger alarm centers, hereinafter also referred to as control centers or control centers, are known in various forms. Danger alarm centers are understood to mean fire alarm control panels, gas alarm control panel, radio control center, spark extinguisher control center, extinguishing control panels or hazardous signal detection and extinguishing control panel.

At such danger alarm centers participants are connected via signal-conducting connections, such as hazard detectors, such as gas detectors, fire detectors or spark detectors. The hazard alarm centers process the signals of the participants and evaluate them. In the case of detection of a hazardous condition, such as a fire, registering sparks in manufacturing processes or containers or, for example, exceed predetermined gas concentration values, pre-alarm or alarm signals are generated by the hazard alarm center, displayed and / or forwarded to higher-level systems or to persons. Depending on the intended use, the hazard alarm centers are configured by specifying configuration parameters so that alarm means and / or protective devices such as extinguishing systems are activated in response to an alarm signal.

The WO 2004/010399 A1 discloses a fire alarm panel with a front panel comprising a display and function keys. The danger alarm center is configured by transmitting a configuration file to the hazard alarm center.

The JP 2000 222654 A discloses a hazard alarm center, comprising: a housing, a first electronic module with a central computer unit, a stored programming with at least one configuration module, a detector signal detection unit and a drive unit, a second electronic module, which is formed on an outer side as a control and display front panel with Switching elements and lighting means, wherein the second electronic module is signal-conducting connected to the first electronic module and is adapted to that set configuration parameters of the configuration parameter setting means are taken from the first electronic module for receiving and processing in the at least one configuration module.

A disadvantage of known hazard alarm systems is that the configuration is a time-consuming and complex process, which requires the use of a separate computer-aided commissioning and configuration tool, such as PC, laptop, smartphone or similar devices. In addition, during commissioning and / or configuration of the hazard alarm center, a signal-conducting connection must be established between the computer-aided commissioning and commissioning Configuration tool and the danger alarm panel are established. Further disadvantages are the high production costs when using displays for displaying and creating the configuration files.

The object underlying the invention is therefore to develop a hazard alarm center, which allows a simplified configuration of the hazard alarm center, without the use of a separate computer-a commissioning and configuration tool, such as PC, laptop, smartphone or similar devices. At the same time, a cost optimization of the production should be achieved. This object is achieved by a danger alarm center according to the features of the first claim. The dependent claims 2 to 10 give advantageous embodiments of the invention.

The emergency alarm center according to the invention comprises a housing and a first electronic module, which is releasably secured in the housing, with a central computer unit, a stored programming with at least one configuration module, a detector signal detection unit and a drive unit.

Furthermore, the second electronic module is preferably set up such that set configuration parameters of the configuration parameter setting means are taken over by the first electronic module for receiving and processing in the at least one configuration module.

Preferably, the danger alarm center is designed as a fire alarm panel, gas alarm, radio center, spark extinguisher control center, extinguishing control panels or Hazard signal detection and extinguishing control center.

Throughout the description of the invention and in the exemplary embodiments described, the phrase "a configuration module" or "the configuration module" is preferably "at least one configuration module" or "the at least one configuration module" to understand.

In a particularly preferred embodiment, the second electronic assembly is created on the basis of a printed circuit board, which has on the outside a front foil with foil buttons as switching element and associated bulbs in the form of LEDs and preferably transparent insertion pockets for sliding signs.

In an advantageous embodiment, pre-alarm events are also detected. It is advantageous that the detection of sparks on a first limit line for a first protection area is possible and the fire detection with fire detectors on a second limit line for a second protection area. Thus, with a single hazard alarm center different hazards can be detected, such as instantaneous radio detection in the millisecond range and fires in the second to minute range with an analysis time to verify the signals of the detector whether a false alarm is present.

The detector signal detection unit is connected, for example via connectors or terminals with at least one limit line. The limit line is to be understood as a connection line with at least one participant. Preferably, a two-wire line is used and forms a closed circuit with a terminal resistor R _E and at least one participant. This line will also be referred to as a signal line.

If several subscribers are used, these are arranged in parallel with the terminal resistor R _E as the last subscriber. The circuit of the detector signal detection unit and the programming of the central computer unit is set up and designed such that the current is measured in this circuit and the measured currents are evaluated in accordance with predetermined limit values. Thus, signal lines for wire break and short circuit can be monitored and signals from subscribers, which are connected to the detector signal detection unit, detected and evaluated to alarm values.

In a preferred embodiment, an automatic quiescent current adjustment is triggered manually during commissioning, in which the quiescent current of the limit line is measured with all participants and contact resistance and stored as a base against which all current changes are measured.

It is now continuously the quiescent current I ₀ and the current changes measured, which are caused by connected participants, or the connection or disconnection of participants and / or by impedance changes in case of wire break or short circuit of the signal lines. When falling below and / or reaching and / or exceeding a preset limit value, in this embodiment variant of a current limit value, this limit value measurement on the limit line is detected by the detector signal detection unit.

The detector signal detection unit measures the current change in both variants and checks whether the preset or current limit values for the alarming or wire break and / or short circuit are undershot and / or reached and / or exceeded.
