    Good morning
    While tidying up the garage I found a working HET24 Hormann module.
    I would like to open the wicket from the remote control.
    I have an electric strike and this control unit but it only gives an impulse, not a current. What else do I need to "insert" between this control unit and the lock to make it work?
    If possible, please advise me of a specific hardware solution, i.e. what I should buy so that the impulse gives a voltage of +12 to the lock.

    Thank you and best regards

    I have the power supply but what does the power supply have to do with the relay?
    The wicket system is on a Kenwei 703 intercom.
    This HER24 relay seems to work like a button so I guess it needs to be plugged into the circuit that opens the wicket from the intercom?

    Nice of you to share with us the information that there is also Kenwei on the way - yes, it has to be connected as a lock release button (terminals S1 and S2).

    You need to buy a PZ9-PM lock opening extender.
    This controller converts a short-to-ground pulse, or a positive voltage pulse, into a shorted relay tic for a specific time.

    A simple relay with a hold, nothing more.

    Good evening
    One more problem arose before I started adding the relay.
    Well, in the existing system it turned out that the camera image is there, but there is no bell signal and the opening from the internal panel of the security doorbell.
    I have checked the power supply of the security gate and it is ok. The power supply of the internal module works. The camera works.
    No bell signal and no response to the open button

    If I solve the problem, I understand that I have to connect the het24 to the line which goes from the outer module to the control unit on the S1 and S2 lines, so to speak, between the outer module and the control unit and nothing more is needed, yes? Or can I connect it to the S-call (s+, s-) on the inner module? the latter option suits me better

    Check the wiring.
    You plug in the HET as per the instructions, in series a relay with a time delay.

    I will continue
    so there has to be an additional relay? I have an electrovalve with a memory so after a pulse it stays open until closed again.
    I don't have the manual. I have one for Kenwei, but I don't understand
    There are two places, one between the outdoor unit and the lock and the other right at the exit of the indoor unit
    Between the outdoor unit and the deadbolt there is a marking "K button to open the deadbolt optionally" and at the indoor unit "monostable normally open button"
    As I understand HET24 only gives a pulse so I can connect it under "monostable"? and this is sufficient or do I have to connect it as a K-button?
    Thanks for your patience

    So relay not needed, pity you are so perfunctory with the information ;)

    .
    And this is where you plug in with the HAT - you can use a piece of wire to short-circuit these pins and test the function - short-circuiting S1 with S2.

    Yes.

    You need to connect it under K.

    Thanks. I am dosing the information because I am discovering more and more things myself ;-) .

    The HET is 12-24v so 12 is probably enough for him. The name is HET24 but on the board it is 12-24V
    I have connected it to 12V and it gives a signal

    Hello
    I still haven't managed to put it together. I have changed the intercom to a simple one from castorama without video
    I connected het24 to the power supply and here there is no problem. The problem is the opening of the electorail
    I have an electric strike with „memory” that is, when pressed there is a )probably) power failure. The bolt releases and stays open until the gate closes. Can this het24 relay handle this? If so, where do I plug it in?
    I have connected it directly to the deadbolt but this is not it
    Regards
    kuba

    And what kind of "simple intercom from Castorama" do you have?

    I gather from your description that you don't understand the operation of the electric door strike.

    Greetings

    The intercom is a wall-mounted intercom without a handset Blyss B-1
    It may be that I do not understand. For this reason I ask the wiser and I hope for a bit of understanding and explanation :)

    If the intercom is working properly, you connect the HET24 contact in the uniphone under 3-4.

    Greetings
    .

    thank you very much for your help
    tomorrow I will connect as you wrote
    Fortunately I have two free cables in the twisted pair gate - intercom

    kind regards

    This is another question of the naive kind …
    Do I have to het24 a separate line or can I plug in those cables that go from the intercom panel to the deadbolt?

    I connected according to the recommendations of user Ircys, who in fact solved the whole problem and for which I am very grateful.
    Everything is working fine. Remotes programmed and finally no need to fly home to open the gate.
    Thank you and best regards

Topic summary

The discussion addresses how to connect an electric door strike to the HET24 Hormann controller, which outputs only an impulse signal without direct current. The HET24 module functions as a relay providing a pulse, requiring integration into the lock release circuit, typically between the outdoor intercom unit and the control unit on terminals S1 and S2 or the "K" button input. A power supply for the lock is necessary but separate from the relay function. For electric strikes with a "memory" (latching) function, the HET24 can be connected to the intercom's relay contacts, such as terminals 3-4 on a uniphone system, to trigger the strike. Some users recommend using a relay extender like the PZ9-PM to convert the pulse into a relay contact closure if needed. The discussion also clarifies that the HET24 operates on 12-24V and that no additional relay is strictly required if the strike and intercom wiring are compatible. Practical wiring advice includes testing by shorting S1 and S2 terminals and connecting the HET24 in series with the lock release button circuit. The solution was successfully implemented with a Blyss B-1 intercom and a Kenwei 703 system, enabling remote opening of the wicket via programmed remotes.
