Description

Component for a fire protection device, fire protection device and fire protection system

The invention relates to a component for a fire protection device, in particular a signal transmitter and / or an alarm device and / or an actuator, a fire protection device, a fire protection system with a fire protection device and a method for configuring a component. Fire protection devices are known in principle. Fire protection devices usually have a hazard alarm center, in particular a fire alarm center. Fire protection devices are generally used to detect a fire and to emit a warning signal, for example an acoustic and / or visual warning signal. In addition, a fire protection device can be set up to initiate a suitable fire extinguishing measure.

Limit value technology, for example, is used as the reporting technology. Fire detectors in limit value technology trigger an alarm when a predefined limit value is reached. With limit value technology, the detectors are usually wired in a line in the stub, at the end of which there is a resistor. Fire detection is implemented by monitoring this resistance. If a defined threshold value is exceeded, the fire alarm control panel triggers an alarm.

The signal generators generally include resistors, in particular combinations of resistors. In the signaling devices connected via limit value technology, the corresponding resistor combinations usually have to be manually installed. The assembly is time-consuming and can only be checked with great effort in the de-energized state. The resistance circuit depends on the central unit used. For this reason, a specific resistor combination for the signaling device must generally be provided for every fire alarm control panel available on the market. Furthermore, the signal generators can lose their official approval if a change takes place on the signal generator, for example resistors are changed and / or introduced. The same applies to alarm devices and valves. Should a modified resistor or a modified resistor combination be required in a signal transmitter, these are usually completely replaced. This is the case, among other things, when a different fire alarm control panel is used. A further disadvantage is the long installation and commissioning time.

The following documents were named in the search report of the German Patent and Trademark Office on the priority application: DE 102014225297 B4, DE 102015223253 A1, FR 2966963 B1, US 2018/0182233 A1.

It is therefore an object of the present invention to provide a component for a fire protection device, in particular a signal transmitter and / or an alarm device and / or an actuator, a fire protection device, a fire protection system with a fire protection device and a method for configuring a component that can be used individually and has a short assembly and / or commissioning time.

According to a first aspect of the present invention, this object is achieved by a component for a fire protection device, in particular a signal transmitter and / or an alarm device and / or an actuator, comprising: a configuration unit adjustable with a setting value, a first interface for input and / or output of configuration data of the component, the configuration data containing the setting value, characterized in that the first interface is set up for wireless transmission of the configuration data using NFC technology. The wireless transmission of the configuration data using NFC technology means that the setting values are set in the adjustable configuration unit. These setting values can be adapted according to the specifications of the limit value group or control group of the different fire alarm control panels. The solution according to the invention enables a shorter assembly and commissioning time. In addition, there is the possibility of a higher standardization of the components, since the components can be designed the same for different fire alarm control panels. This is due in particular to the fact that the individuality by means of the adjustable configuration unit and the subsequent transmission of the configuration data, the setting value is comprehensively achieved by means of NFC technology.

A signal transmitter can be, for example, an industrial alarm, a white alarm, a temperature switch, a pressure switch, an RAS system, a float switch and / or a leakage alarm. The actuator can be a solenoid valve, for example.

The component includes the adjustable configuration unit. The configuration unit can be set with the setting value. The configuration unit can be, for example, an adjustable resistor.

The component also has the first interface. The first interface is in particular arranged and designed to input configuration data and / or to output configuration data. An input can also be understood as a reception. The configuration data are used to configure the component. The configuration data include at least the setting value and can also include further data. The component is characterized in that the first interface is set up for wireless transmission of the configuration data using NFC technology. NFC stands for near field communication. This is an international transmission standard based on RFID technology, particularly for the contactless exchange of data. This exchange preferably takes place via electromagnetic induction using loosely coupled coils. The exchange usually takes place over short distances of usually a few centimeters.

The invention was based, inter alia, on the knowledge that unconfigurable components of fire protection devices require a high level of assembly and

Have commissioning effort. In addition, if the facility or the system is changed, these can usually not be changed or can only be changed with difficulty. In addition, changing such components is usually associated with a loss of approval, so that the component either has no approval or a new approval is required. The component according to the invention, on the other hand, enables individual configuration, taking into account the necessary boundary conditions. The adjustable with the setting value

The configuration unit can be, for example, a configurable resistor that can be changed by means of the setting value. In one alternative, the adjustable configuration unit is designed as a configurable resistor, the setting value being a resistance value of the configurable resistor. In addition, it can be provided that the configurable resistor is designed as an alarm resistor, the setting value being an alarm resistance value of the alarm resistor. When a fire is detected, a switch can be operated within the component, for example, which switches the alarm resistor and thus an alarm is triggered.

A further preferred development of the component provides that the configurable resistor is designed as a terminal resistor, the setting value being a terminal resistance value of the terminal resistor. The terminal resistor is usually used for line monitoring. The terminal resistor can therefore also be regarded as a monitoring element for the line.

According to a further preferred development of the component, it is provided that the configurable resistor is designed as a monitoring resistor, the setting value being a monitoring resistance value of the monitoring resistor. The monitoring resistor can also be used to monitor a line and / or a detector.

Another preferred development of the component provides that the setting value relates to at least one of the parameters contained in the following list: a line voltage on the signal transmitter; a state of a contact; a sensitivity; a voltage inversion function; a solenoid valve parameter, in particular a value for trips; - a digital nameplate, preferably with manufacturing data;

Location data;

Plant data, in particular a location, a

Detector group affiliation and / or a date of installation.

In addition, it is preferred that the configurable resistor is designed as a transistor, in particular as a power field effect transistor, preferably as a temperature-compensated power field effect transistor, or includes one. As an alternative or in addition, the configurable resistor can be designed as a digital potentiometer or comprise one. A power field effect transistor is an adjustable power resistor. The resistance value of the power field effect can be set using a so-called gas source voltage. In order to set a constant resistance, the circuit is usually temperature compensated. A power field effect transistor has the advantage of an essentially constant resistance, which essentially always allows the same current to flow, that is to say in particular the current intensity remains essentially constant.

A digital potentiometer is an integrated circuit in which a specific resistance value can be set via a digital interface. This resistance value is essentially accurate. A digital potentiometer is easy to implement and the technical and financial outlay is low. In addition, it can be preferred that the configurable resistor is designed as a selection circuit, in particular as a multiplexer with resistor circuitry, or includes one. A multiplexer is a multiple switch that is digitally controlled. Different signals can be switched on at different inputs of the multiplexer. Demultiplexers can also be used. A demultiplexer or DEMUX (er) for short can be the counterpart to a multiplexer. With the demultiplexer, an input signal is switched to one of several outputs. For control purposes, the demultiplexer has control inputs which are required for switching over its switches. The different resistors can be connected downstream so that fire alarm systems from different manufacturers can be used. The implementation is comparatively simple with multiplexers and demultiplexers.

Furthermore, it is preferred that the configurable resistor is designed as a current sink or comprises one or more such. The current sink can generally be described as a constant resistance that always allows the same current to flow. The advantage of a current sink is that it requires little space and has constant resistance. A current sink for voltages of up to 40 volts can also be provided. In a further preferred alternative of the component it is provided that the adjustable configuration unit is alternatively or additionally designed as a contact, the setting value defining a function of the contact. The contact can be designed, for example, as a normally open contact, also a working contact. Of the Normally open contact closes the contact when the contact is actuated. In addition, the contact can be designed as a break contact, also a break contact. The normally closed contact interrupts the circuit when this is actuated.

It is also preferred that the component comprises a visual display and / or an acoustic acknowledgment of a function. The end devices that are programmed usually have no displays. This means that the operator cannot understand whether the terminal has been programmed correctly. After successfully programming a function, e.g. setting a value on the terminal, this is signaled, for example displayed, by an optical or acoustic notification, the acknowledgment, on the programming device. Before this, the data is read from the terminal device and compared with the data on the programming device. This is followed by the optical or acoustic notification, i.e. acknowledgment.

The component preferably has an antenna, in particular an NFC antenna, the antenna being integrated in particular together with the first interface on a circuit board. The antenna can be implemented, for example, by conductor tracks integrated in the printed circuit board. The integration on a common circuit board reduces the complexity of the component.

Preferably, the first interface is used to implement an access control, in particular including authentication, to secure the data, in particular the configuration data, against unauthorized access. This ensures that the configuration data, for example, is only transmitted by authorized persons and that the integrity of the fire protection device, for example, is not endangered. Various possibilities for implementing such an access control are known to the person skilled in the art and can be used advantageously.

According to a further aspect of the present invention, the object mentioned at the beginning is achieved by a fire protection device comprising a

Hazard alarm control center, in particular a fire alarm control center, and a component according to one of the design variants described above.
