Thank you all.

I have a simple project in the design of fire alarm panel.

I have not used  microcontroller in this project.

and I use digital ICs,lm339 and 4001

and i have a control panel bord that (There are parts,lm339,4001)

Which is connected to 8 zones.

if you have same circuit diagram,please help me.

The essential point,My project is educational and not commercial !!!!!

with all greatest respects, a fire alarm is designed to detect fire - not cause it.

you are tinkering in an area that could cost lives if it fails. for that reason alone please please use tried and trusted commercial equipment.

No, we've put up with your crackpot idea for yrs....

If somebody wishes to build there own controls, f'kin good luck to them.

i''m astinished at the flipancy dusplayed, i think the possible consequences require the application of common sense.

this guy is trying ti design a fire panel with little idea why the regulations are their, not just any fire panel btw, but an 8 zone version.

now that implies to me a reasonable size building would you thnk? perhaps offices, factiry even a block of flats or a playschool

joke all you want, i just hope your concience's can remain a clear!

I think from what the op said he's doing this out if interest on a bench rather than in a building?

8 zones?

no idea of his capability, no idea if his experience, no idea of his qualifications

their are plenty of books on basic electronics, b.bannini will possibly have a basic diagram, we should simply not be encouraging or up for the risk to life of others!
