[Solved] Malfunction of symmetric door strike with lock and memory - cable direction

Hi. I have a problem with my electric lock (symmetrical with lock and memory). It only works when it is in the position where the cables go from the top, but when they go from the bottom, it does not engage (but you can hear a snap in it). This model should work in this position as well as the other. The current goes to it properly, but when I connect it to the power supply briefly at home, it then works fine. What should I do?

I had the same case. The reason turned out to be that the fitter had trimmed the wires with a lock, because he had bent them by force. This caused a short circuit.

After cutting off the damaged cable, everything is fine.

I checked it on 2 cables (thinner and thicker) and same situation. Also I have 2 solenoid locks and both work the same so a faulty solenoid lock is rather out.

Added after 9 [minutes]: .

I would also like to point out that 13V goes from the power supply (din power supply preferred) to the video doorbell in the house via a 50 metre 1.5mm cable and there is already 12.5V at the doorbell. On the other hand, the power supply to the doorbell outside goes back via a twisted-pair cable (i.e. approx. 0.5 mm) and there it is already 10V. At the electric strike connected by a 3 metre long 1.5 mm cable there is already 8.5V. I don't know why this is so.
As I said it should work in both positions, but it works in only one, so a short circuit is ruled out. But the hitch is low current, so it should still work in that position. It was even working, just suddenly stopped.

We don't know either, but this is the cause of the electric strike working like this - too much voltage drop. Look for the problem in the wiring or in the video intercom itself.

It was enough to connect the power supply directly from the power supply to the station outside and not from the leads from the monitor. The monitor was giving too little current and the solenoid was not working properly.
