Buzzer on the doorbell rings when he wants to.

I have on the door 1 push button Brand Simón series 27 play receipt with 1 bell screen printing. And in the hall I have 1 buzzer Mark Simón seri 27 play, with pitch adjustment. The resistance between its two contacts of 2k ohms. It turns out that if I turn the regulator at 1 point it stops sounding and if I keep turning it increases the tone, it seems strange to me that at 1 point it stops sounding. But what worries me is that if I leave it well regulated and ringing ... sometimes the doorbell does not sound and others do. How could I know if the buzzer is damaged or the button? Greetings!

If it rings at one point in another, then the problem is a buzzer because if it were the bell, the buzzer will not ring at any time.

The buzzer has a screw that clicks on the rotation and gives more or less energy to the buzzer. When I turn to a minimum it does not sound when I pass from half turn upwards begins to increase the tone. Is this tonle of tone the one that is damaged? What can be a switch with several outputs ?, because it has the click click and is not silent like a potentiometer. I measured resistance between its phase input and neutral return and mark 2 K ohms and does not change when turning the tone screw. Greetings!

Will the buzzer tone extension mechanism be damaging the system?

Hello The first thing you can do is bypass the button on the street front. If the buzzer sounds correctly, you can disassemble the button and clean it. The button internally has a spring that maintains continuity between the button itself and the body of the button, when this spring becomes dirty or oxidizes it stops making contact at times. Regards

I find this solution interesting, I will see if it can be disassembled as the Simon 27 series mark, it gives me that it is electrowelded. But on the other hand, what component will the buzzer coil have to select the increase or decrease of the tone? Buzzer contacts give me 2k ohms, will it be an acceptable value?

Hello, even if it is electro welded it can be bridged. Either way, this is what I would do to start, it is the simplest.

Ricardo, but it is that the failure is very occasionally, it is not something of a series of failures followed. That's why I wanted to know if there was a multimeter test to discard the button. I measured resistance of closed circuit and I scored 2 r, then a series of 0.1ry and finally of continuous 0.00 r. I thought that if it gave me more than 0 r, it was bad but as I saw it started bad and ended good. That's why I'm confused.

Like all things, first you start with the simplest. And the simplest is to test the button.

Ok, but for the bridge test, it must be just when you see it not working. I will do so and comment. I hope to fail again shortly. The system is demonized. Thank you!

Today I replaced the button, the new one of the same brand that I put had 1.9 R, the old one I replaced just measured it and it gives me 26 R. I think this reading of 26R, when the factory pattern marks 1.9 R gives me Foot to affirm that it was the button. What do you think of my reasoning? Greetings!

Works?

What do you mean?

If you mean that if the system in which I have replaced the button works, I say yes. But before it also worked, but when it seemed it stopped working, hehehe.

Hopefully now it will not fail and be repaired. Regards

Yes Ricardo I hope so, but do you know if my resistance measure is an indication that it was the contact that failed to have a lot of ohmic value? Thank you, 1 greeting!
