In particular, the security alarm system comprises more than ten security detectors, preferably more than fifty security detectors and in particular more than two hundred security detectors. The security detectors are designed to monitor a surveillance area. In particular, each security detector monitors its own surveillance area. The security alarms are arranged, for example, in or above the surveillance area. The safety alarms are preferably fire detectors, for example active or passive fire detectors, moisture meters, temperature sensors or other sensor devices for determining a safety-relevant event.

The security alarm system comprises at least one memory module. In particular, the security alarm system comprises at least two memory modules, preferably more than ten memory modules, and in particular more than one hundred memory modules. It is particularly preferred that the security alarm system comprises a number of memory modules corresponding to the number of security detectors. The security detectors are connected to the memory module for data purposes. For example, the security detectors are connected to the memory module by means of a radio link or a cable connection. In particular, it may be provided that the security alarms are connected to one another by data technology, for example with a radio connection or a cable connection. The security detectors are preferably remote security detectors, wherein the remote function takes place, for example, by means of the data connection and / or realized. The memory module can be realized as a computer unit, as a processor unit or as a microchip.

The security alarm system and / or the security alarm are designed to generate a maintenance data record during maintenance and to provide the maintenance data record to the memory module. In particular, it may be provided that the security detector provides all its memory modules with its maintenance data record and / or provides all other security detectors with its maintenance data record. The security alarm system and / or the security alarm are preferably designed to generate and / or provide the maintenance data record after completion of the maintenance. The maintenance record includes, for example, type of maintenance performed, the time of maintenance performed and results from the maintenance performed. The maintenance may be for example a function test, a battery test or another test. In particular, it may also be provided that the maintenance of the safety detector is a mechanical maintenance that is performed by an external to the safety detector.

The memory module has a block data string. In particular, each memory module has a block data string.

In particular, the memory module a Genesis block record, wherein the Genesis block record is a first block record to which all other block records are appended and / or which forms the origin of the block data string. In particular, it is provided that an attached block data record in the block data chain is immutable and / or is no longer changed. For example, the block record includes a block record header and a list of maintenance records.

Alternatively, it may be provided that if there is a non-majority match of the block data record and / or the maintenance data record, a warning is displayed that this data record may be damaged and / or incorrect. A majority agreement is, for example, if the maintenance data record and / or the block data record are stored identically in more than half of the requested memory modules. This refinement is based on the consideration of providing a security alarm system which only makes unadulterated service data records and / or block data records available to a user. In particular, such a tamper-proof security alarm system is provided.

An embodiment of the invention provides that the security alarm system comprises a test module.

For this purpose, the test module comprises, for example, a memory unit, wherein the test program is included on the memory unit. Specifically, the test program includes tasks that must be performed in order for the safety detector to be maintained. The triggering for the execution of the test program causes the security detector, for example, to independently perform a maintenance and / or visually or acoustically indicate to a third party that maintenance is necessary. If the third party carries out the maintenance or if the security detector itself is waiting, the maintenance data records are generated and / or generated.

It is particularly preferred that the test program comprises a test cycle. The test cycle indicates, for example, in which regularity the safety detector is to be checked. The test module is preferably designed to trigger the safety detector based on the test cycle to a regular performance of the maintenance. For example, the test cycle is a once-yearly maintenance, a half-yearly maintenance or a monthly maintenance.

Optionally, it is provided that the test program is a country-specific or application-specific parametrisable test program. For example, different test cycles are required in different countries. On the other hand, it may be provided that a security detector in a hazardous area, for example in a laboratory, should be checked more regularly than a security detector in a residential building. In this case, it is provided in particular that the security detector receives its position, its country of assignment or its purpose from a central office. For example, the central office is a central one Monitoring device, an alarm center or a central server to which the security detectors are connected. In particular, provision may be made for the security detector to be provided with its position, its country of assignment or its insert by the memory module. The test module is preferably designed based on the deployed use, position and / or country of use parameterize the test program. For example, the central office informs the security detector that it is a fire detector in a German laboratory so that the test program stops the test cycle once a month. The security detector is finally checked once a month, with maintenance data records being provided once a month in the memory module.

A further embodiment of the invention provides that the maintenance data record comprises an operating state of the security alarm. For example, the maintenance record includes a period of time in which the security alarm was active and operational and / or a period of time in which the security alarm was inactive and / or inoperable. This embodiment is based on the idea of informing an insurer and / or a third party about the risk assessment of how safe and / or close-meshed the monitoring of the corresponding area is.

A further subject of the invention is a method for operating a security alarm. A safety detector generates and / or maintains a maintenance record during maintenance. This maintenance data record is provided to a memory module for storage, for which purpose the maintenance data record is stored in a block data record and the block data record is added to a block data string.
