ljcox said:Here is how I would do it with relays.
The "total operation time" in my circuit is done by R1 & C1 & Q2. The timing starts if X1, X2 or X3 are operated. I noticed that your circuit has a delay in the operation of the Door Solenoid. I do not think that is necessary, but this may be one of your "traps" intended to make it difficult to circumvent the system. Such a delay could be added to my circuit if necessary.Hayrettin Demir said:You design have more nakeds.

So my shema have very very traps. I don't know what you mean by "traps". I think you mean that your circuit includes several techniques to make it difficult for someone to open the door without knowing the code.
Example that have Total Operation Time , and more Turn On and Turn Off Circuits.Thats important. I don't understand "Turn On and Turn Off Circuits". I think you mean delay circuits.

Yes , R12 is extra.

And this topic name is "Basic , with Relay's Code Circuit Diagram... ".
Also with not other Electronic Component.(IC , PIC , or microProcessor).
I think you mean that you want to do it with relays, not with electronics.
nakeds is exposed......I don't understand what you mean by "nakeds"
Ok...I explain later.I don't understand "Turn On and Turn Off Circuits".

What error?Hayrettin Demir said:nakeds is exposed...

Ok...

So , please see your in shema error.

3, 4. Yes, the current through the X4 and B4 contact is Ir +
Ids.
Why is this an issue?
ljcox said:Now I understand.
The coil current of DS is too much for the B4 contacts.
Here is a simple solution and it has the additional advantage that D5 is not required.
