    Hello.
    I am writing a thesis on alarm systems (or more precisely, I create my own alarm control panel based on a microcontroller).

    I am looking for specific information on the differences between the GRADE grades. However, this is not about general differences included in the GRADE grades themselves.

    I am interested in specific differences resulting from the alarm system requirements for meeting certain GRADE 1-4 grades.

    I found a part of this information in a pdf called "nazwa_sswn_tecnoalarm", but some information is incomprehensible to me, and the whole seems to be incomplete.

    If anyone has any materials, please share it.
    best regards

    The only documents where you will find complete, detailed information are the standards themselves, for starters PN-EN50131-1 and (speaking of the control panel) PN-EN50131-3. You can buy them at PKN, but if you are studying (thesis), look for the standards reading room at your university.

    I know about the standards, but they are difficult to access.
    Of course, the purchase is not possible due to costs.

    It does not have to be very detailed information, it is important that in my diploma thesis I can at least show the basic differences in GRADE grades, say for a detector, siren, centrepieces, centrepieces, etc.

    The problem is that half of the standard are tables that show the requirements and differences for individual GRADE ... Unfortunately, there are no shortcuts.

    Exactly like the colleague above. I will just add that you will not find it profitable to look for standards on the Internet, because you probably won't find them there. The standards are quite expensive (about PLN 150 for one sheet of 30-40 pages). There remains a reading room, etc.

    When it comes to the differences between the various degrees, here is a small example:
    In each of the 4 levels (1-4), the time to enter the protected facility cannot exceed 45 seconds.
    In stages 1 and 2, the system must be able to withstand backup power (usually a battery) for 12 hours.
    In stages 3 and 4, it is already 60 hours. Only in the case of stages 3 and 4, when the system is monitoring the events to a monitoring station (security agency) and one of the information transmitted is the main power status of the control panel (up / down), the time of 60 hours can be reduced to 30 hours.

    The standard (PN-EN 50131-1) also states that at the 1st and 2nd stage, continuous signaling of the arming status is allowed (i.e. the LED on the keypad may be on when the system is armed). For grades 3 and 4, it is required that such an indicator will switch off automatically (e.g. a diode) after some time (the time is not defined in the standard).

    It seems to me that when you are designing an alarm control panel, you should focus more on the installer manuals for each control panel. There you will learn how to connect the detectors, how the control panel tests it (and tests it through the A / C converter, which measures the voltage on the line - the detector represents a certain resistance, which together with the resistor on the control panel board forms a voltage divider).

    Added after 2 [minutes]:

    I also recommend: http://www.zabbezpieczenia.com.pl/. There you will find many documents in PDF that also deal with standards, and you can enter this at the end of the work ;)

    Therefore, I am not going to mess around with norms.
    Especially that in the diploma thesis it does not have to be described in detail and in detail.
    It is enough for a potential reader to know a few basic differences between the grades.
    For example, that the number of digits of the code for stage I is 3, for II is 4, for III is 5, for IV it is 6 or, for example, which standard requires tamper protection, etc. etc.
    As I say, more "general" and basic (without going into technical details).

    If someone had any materials (or I know in a given area, please share them here or in the PW message).

    Thanks for the answers and best regards

Topic summary

The discussion centers on the specific requirements of alarm systems categorized by GRADE 1-4, particularly focusing on the differences in alarm control panel specifications based on microcontroller technology. Participants emphasize the importance of consulting the PN-EN 50131 standards, specifically PN-EN 50131-1 and PN-EN 50131-3, to understand the detailed requirements, which include factors such as entry time limits, backup power duration, and code digit requirements for each grade. For instance, GRADE 1 and 2 require a backup power supply for 12 hours, while GRADE 3 and 4 require 60 hours, with some exceptions. The discussion also highlights the need for tamper protection and continuous signaling requirements, suggesting that a thorough analysis of the standards is essential for developing a compliant alarm control panel.
