Question Quiz Lockout Buzzer

This Post based on:

hello hainhi,
ok here is what u need to bulid 1.
2 - momuntary push buttions
1 - togel switch
2 - 2 pole relays 1 normaly open contact
and 1 normaly closed contact
2 - lights
1 - buzzer
1 - transformer of relay voltage.
now how to wire this
1. connect 1 screw of togel to transformer output
2. from other screw on togel connect to the common contact of both relays
3. from the normaly closed contact of relay 2 connect to 1 side of momtary pushbutton 1
4. from the normaly closed contact of relay 1 connect to 1 side of momtary pushbutton 2
5.connect from normaly open contact of relay 1 to other side of momtary push button 1, 1 side of buzzer, 1 side of light 1, and to 1 side of coil on relay 1
6.connect from normaly open contact of relay 2 to other side of momtary push button 2, 1 side of buzzer, 1 side of light 2, and to 1 side of coil on relay 2
7. connect from other side of light1, light2, buzzer, coil on relay1, coil on relay2 to other side of transformer output.

what hapens here is whin contestant 1 pushes there buttion it sounds buzzer and lights there light and disconects power to constant 2 button. the buzzer and light will remain energised till togel switch is thrown reseting system. i built 1 of these for my church youth group so i know it works. if u r confused i can e-mail u a ladder diagram on how this works and it may make more sence 2 u

Hi, can I can please get help with the quiz lock out diagram? I am stuck. I wired as instructed, but I am not getting any sound or light when I press my buttons.

Welcome to the forums.

This thread is 14 years old and it would appear that the original poster and responder are no longer with us so we've created a new thread just for you.

Did you try drawing out the circuit ? That usually helps.

I'll check over the circuit and see if I can be of some help.

I'm sure someone will be along soon to help you now that the weekend is here. Been a bit of confusion because you answered a very old thread.

Thank you for responding. Yes I drew the diagram before attempting the actual wiring layout. What I am not sure about, is when the instructions say; connect 1 side of coil to another coil on the other side. I am using two 5 bosch 12v relays.

It would be a pleasure to see a diagram.

Thanks in advance for your help
Hugh

Good choice of relays.

I'll try to draw up a wiring diagram.

Try this:

Label the pushbutton terminals as 1 and 2. Label the transformer secondary (low voltage load) terminals as 1 and 2. Label the relay poles as 1 and 2. For each relay pole, identify the terminals for normally open contact, common, and normally closed contact and label them. (Relay pole may lack either the NO or the NC contact.) Label the light and buzzer terminals as hot and neutral on each. If you are a purist, the neutral should connect to the lamp socket outer shell although it does not matter for this low voltage application.

Connect transformer secondary terminal 1 (power) to pushbutton terminal 1 and also to relay pole 2 (used as normally open) common.

Connect pushbutton terminal 2 to other side relay pole 1 (normally closed) contact.

Connect relay coil terminal 1 to same side relay pole 2 normally closed contact and to light hot and to buzzer hot and to opposite side relay pole 1 common.

Connect relay coil terminal 2 and buzzer neutral and light neutral to transformer secondary terminal 2 (as ground/neutral).

Repeat for other side.

Master release toggle switch can either be ahead of transformer secondary power to everything or can be in transformer 120 volt primary.

Good Job Bahtah, appreciated your help.

A friend of mine only has one (1) BUZZER. Could you please assist with drawing a diagram using
2 RELAYS, 2 SW and 2 LIGHTS?

Thanks

Just don't use the buzzer. The circuit is the same as the buzzers and lights are wired in parallel.

Thanks PJmax, I was considering that too, but the children love to hear the sound of the buzzer and to see the lights go off.

The question is, how can we get one buzzer to work with the 2 switches?

You mentioned he had one buzzer.... you didn't include it in your list of items to connect.
No problem. See new diagram. You will need to pickup two diodes. Nothing critical....1A 50v is fine. 1N4001 Fairchild Semiconductor | Mouser Radio Shack should have something similar.

Not sure how the buzzer will react with 1/2 wave DC from the diodes. You'll have to try it.
