    Connecting any detector to any control panel - guide

    Many times on the forum I meet with a request to draw a scheme for connecting a given detector to a given control panel, because the instructions do not include how to do it.
    Yes, the Satellite control panel manual will not find information on how to connect a DSC detector, but there is information on how to connect a Satellite detector. And that's enough. This can be done by analogy.
    It is enough to know that each detector has the same and the same effect basic contacts , which simply depending on the manufacturer can be marked in different ways and placed in a different order.

    Contacts that interest us

    o two power contacts Here we give the correct power supply from the control panel (plus to plus, minus to minus)
    o two NC tamper contacts. Shorted when the detector housing is closed and reacts by opening to open.
    o two NC alarm contacts. Shorted when the detector is powered and does not detect motion, responding open to motion detection or power off.

    Now let's look at a few popular models:

    Satel Aqua

    Connecting any detector to any control panel - guide
    NC, NC alarm contacts
    TMP, TMP tamper contacts
    COM 12V power supply

    And how do other manufacturers describe it?

    DSC (e.g. LC 104 or PIR LC 100 detector)

    Connecting any detector to any control panel - guide
    NC, C alarm contacts
    tamper contacts T1, T2
    power supply -12+

    As you can see in relation to the Aqua detector, the alarm and tamper contacts have been swapped with each other. There is also another NO / EOL contact, which should not be of interest to us when connecting the detector to the control panel in a standard way.

    Vidicon Bingo

    RELAY alarm contacts
    TAMPER tamper contacts
    power contacts -12+

    Again a different order, different descriptions, this time for a pair of terminals and not single ones, and this time two terminals (EOL), which remain outside the scope of our interests.

    Which way to connect the detector to the control panel and how to do it

    As you will notice, the instructions contain several different examples for connecting detectors. If your control panel supports this parameterization method (DEOL), then forget about NO, NC, EOL. (below is the diagram from the installer manual for the Satel CA 5 control panel)

    Connecting any detector to any control panel - guide

    Advantages of DEOL (2EOL)

    o With the detector connected in this configuration, the control panel detects three states on one line: normal state, violations and tamper.
    o The status of the zone on which the detector is connected is monitored all the time regardless of whether the system is armed or not. It should be known that the control panel will detect and report as tamper not only the detector opening, but also damage (interruption or short circuit) of the cable to which the detector with the control panel is connected.
    o We save control panel lines by providing alarm and tamper signaling on one line.

    Initially, connecting the detector in the DEOL (or 2EOL) configuration to the control panel may seem complicated. Nothing could be more wrong. It should be remembered only that one resistor connects one of the tamper contacts with the alarm contact, and the other one is parallel to the alarm contacts. You will find out about the benefits of such a system by quickly diagnosing faults during the installation of the system and its operation. To facilitate, manufacturers are increasingly building resistors in detectors and all you need to do is to postpone the appropriate jumpers during installation, remembering not to use both methods at once, i.e. do not put the jumpers in DEOL and do not give external resistors at the same time.

    Examples. In both cases pay attention to the position of the parameterization jumpers (circled in red)

    Notes / FAQ

    o In the attached photos you can see stuck wires in the detectors. This does not look too elegant, but in this way I wanted to draw your attention not to cut free veins and leave a supply of wire in the detector.

    o DEOL parameterization can also be used when connecting detectors without tamper contacts (eg most reed detectors). This makes sense because, as I wrote earlier, sabotage is not only opening the device, but also damage (short circuit, break) on the wires.

    o DEOL parameterization is not only supported by very old control panels. But there are exceptions. Among those designed in this century that do not support this parameterization, first of all Satel Micra should be mentioned. It is not without reason that installers prefer to stick to the name: "Communication module with the control panel option" We will rather not use DEOL parameterization by connecting detectors directly to the communication module. But there are also exceptions that give such a possibility, such as Genevo GSM-8.

    o In detectors, we use resistors (of such values) as imposed by the control panel. Although in most popular control panels from manufacturers such as Satel, Genevo, Ropam, 1.1 k resistors are used for DEOL parameterization, but there are also control panels based on 2.2k (Risco) or 5.6k (DSC) resistors. In practice, this means that by connecting a Satellite detector, e.g. Graphite, to the DSC control panel, we will not use the built-in resistors, and we will have to use those attached to the control panel. Of course, the method of assembly will be the same. However, we will use the built-in resistors in the Satellite detector, e.g. Graphite, connecting it to the Genevo or Ropam control panel.

    o When choosing a given detector parameterization (eg DEOL), remember to choose the same parameterization in the settings of the given control panel zone.

    o If the detector reports tamper during violation (motion detection), it usually means that incorrect resistors were used, the resistors were inserted into these terminals, and the resistor legs were not well seated in the detector connectors.

    o In more advanced exchanges, such as, for example, all "+" integrals, you will also meet something like TEOL (3EOL). It is nothing more than parameterization using 3 resistors, where the control panel detects one more state. This is used, for example, when connecting detectors with anti-masking (by the way I suggest you be interested in detectors equipped with this function). The control panel zone working in this mode detects next to tamper, violation, normal status, and detector masking. In control panels that do not support TEOL parameterization, the detector anti-masking output is simply connected to a separate control panel input.

    Good luck!

    A small note for beginners.
    Please, when laying cables in the detector, pay attention not to lead to incorrect arrangement (short circuit) of the resistors. The detectors or alarm will not damage the detectors, but the detectors work incorrectly.

    Preparation of resistors

    With 1 / 4W resistors there are no major problems, but with 1 / 8W I wrap the U-shaped wire ends of resistors because after connecting to a terminal with a thicker YTDY or UTP cable there is no reliable connection. I do the same with the tip of the insulated wire, which avoids the lack of contact with which I had a few cases after the introduction of 1 / 8W in Satellite.

    In the title I wrote that it is about any detector, and I gave examples only of motion detectors.
    Well, let's look at the inertial detector VD-1 from Satel

    Connecting any detector to any control panel - guide

    Has the same, same contacts as the motion detector:
    o two power contacts (COM + 12V)
    o two tamper contacts (TMP TMP)
    o two line contacts (NC NC), which simply indicate vibration detection for a change
    What's more, even the descriptions for these connectors are the same as for satellite motion detectors.
    If we want to connect it to the control panel in 2EOL (DEOL) parameterization, then we will do it in the way we know at the beginning of the guide.

    As everyone is also a brick from myself (I hope I will not repeat anyone, although I have read the thread (?))

    Where does the name "EOL" come from?
    EOL or - End Of Line ("End of the Line"). It is very important that the end-of-line resistors are ... at the end of the line. So they are supposed to be in the detector, not the control panel (see: popular error of beginners, who install resistors for the EOL configuration at the control panel inputs instead of the detectors).

    What does the current PN-EN50131 standard say about such creations as "DEOL, EOL, etc."?
    Nothing. The standard does not define such concepts, but only indicates that the detector should have, for example, anti-sabotage protection. It does not impose a technical solution, i.e. the standard does not say to insert resistors into the detector. The point is that the installer is to connect elements of the alarm system so that, for example, when the detector senses movement, the control panel knew that it was a move, while the detector knew that the control panel was open (sabotage) when the detector was opened. If the installer feels like it, he can connect the detector in the NC configuration and take several detector inputs. However ... alarm system manufacturers have come up with such "optimizations" as EOL, 2EOL, 3EOL, among others so that you can save the entry of the control panel. Of course, such configurations bring with them other improvements, such as the simple way to bypass the alarm line (by just using the "parameter" on the line, i.e. the resistors). For a person once in the life of the detector, it is not necessary to penetrate the details, but it is worth remembering that ... resistors to detectors are really worth inserting (that is, it's worth parameterizing the alarm lines).

    Nomenclature (various documentation from different manufacturers may state this differently). Generally:

    SEOL (Single EOL) = EOL
    DEOL (Double EOL) = 2EOL
    TEOL (Triple EOL) = 3EOL

    For example, the previously mentioned Integra Plus series (ie Integra, which meets the requirements for stage 3 according to PN-EN50131-1), has 3EOL not because the standard forces (see above). It has 3EOL, because it is more convenient to connect detectors with anti-masking function (it is enough to use one input for such a detector, and it will still be able to control all key signals from this detector).

    From level 3 of the said standard, detectors with an anti-mask function are required.
    But this "anti-masking" is a bit "embarrassing" thing. I can be wrong (standards are more extensive than it seems, especially when it comes to the interpretation of many entries), but the standard indicates that as a part of one of the tests you should use a black card (...). The microfile flips such a card without blinking and the conclusion is that the only "real" antimasking is the one that is based on infrared (of course not on the PIR track, only on the IR transmitter -> IR receiver). This is important, because a large number of detectors with anti-mask function is based on microwave (in dual detectors).
    See: Satel OPAL Plus and OPAL Pro. The PRO version has an infrared antimasking (and has a grade of 3), while OPAL Plus has antimasking implemented in the microwave (and has the degree 2). Opel's Satel is just an example, because what I wrote is not based on the degrees assigned to these detectors, but based on the standard.

    Examples of topics related to connecting alarm detectors to control panels:

    Connecting the Optex BXS ST detector to Satel Integra 32 in DEOL. So, as you know, basically every DEOL operating panel

    Connecting the Satel TSD 1 smoke detector to the Ropam Neo control panel (the same principle applies when connecting to other control panels)

    Two detectors on a 6-wire cable

    Connecting the detector to the alarm control panel on the example of Satel Perfecta + Pyronix DD

    Connecting two motion detectors to one control panel input without resistors (in NC)

    Connecting two or more detectors to one control panel input in DEOL NC (here on the example of reed switches, but the same principle applies also to other devices)

    Connection of two motion detectors to one control panel input in DEOL NC

    And about why you should avoid connecting several detectors under one control panel line

    (And for supplementation) it will additionally detect the opening of the reed switch (A or B), because the VD-1 detector has such a possibility.

    Exactly, because this detector signals on the same contacts both violation of the inertial and reed switch sensors. Which, of course, boils down to the fact that we do not know which of these sensors an alarm was created.
    It is different in a Risco inertial detector with a built-in reed switch. There we have separate signal contacts for the shock detector and separate for the opening detector.
    So we can connect these two outputs to two independent control panel lines.

    However, if we want to connect this detector to one zone, we can use the diagrams contained in these topics:

    Connecting two or more detectors to one control panel input in DEOL NC (here on the example of reed switches, but the same principle applies also to other devices)
