Wow, thanks. I am glad that you like my projects. I thought about a diode, and I will add one in the Mark 2 version. And thanks again, I will PM you my details.

That one looks good, do you still have them? or it? I could try and copy the board design out, im in need of a schematic for one. Excuse my lack of knowledge, but what's a digital? Looks old and interesting.

So this was a bell module? In the loft? Looks to be in very good condition, do you take down many standard bell modules? like SAB modules?

Interesting, I understand, its easier and cheaper to buy a fully made up bell box now. Do you take many of these down? Or have any old stock of these? Would be interesting to see them. I like the fact that the internals of a bell box are on 24/7, 365 days a year, constantly for 20 years or more, never get a break. some very robust electronics.

Thanks, I have one of the "Modern Alarms" bell boxes with these in, will get a pic. Well, mine didn't false alarm at all, during light tests I did, I'm impressed. I know, looked on Google for some pics. Don't know why they couldn't be as simple as the one that I made. Those Hexagon bell boxes were such a good design, shame they changed it. The idea of a foam detector is flawed anyway, by the time it has been squirted? in it would be too late.

Does anyone have any experience with these sorts of detectors that you'd get in older bell boxes? Or know how they worked? I have just made one, using the most simple bits possible, two resistors, an LDR and a 2n2222 transistor. Did they work like that a beam of light getting interrupted, or was it more advanced? Been testing mine, and I couldn't get it to false alarm at all. Thanks, Gabs

Is this something that you designed and implemented? it is a good idea, and would reduce false alarms.

Thanks for that, well, everyone has to start somewhere. I am still looking for an idea, or something I can make, which will be an improvement to the security or electronic industry

I understand that, I definitely wouldn't want to loose money, you got any ideas or suggestions? Want to get into manufacturing

Thank you GalaxyGuy, didn't think o the ongoing support that would be needed. Starting small, I could buy internal sounder speakers, and create my own siren driver circuit put that in, and sell it as a siren with the tamper added. That may be a good start. The shed alarm idea I had I am still working on. I will look at the engineer prices, although I can image they would be high. I would like to design a PIR that can be used anywhere with no false alarms, however the problem is it couldn't be used on the standard 6 core cable configuration, or be used with any panel, e.g. Texecom Medusa PIR will work with an ADE Optima XM I could produce those bell box dummy LED modules, do you professionals use them?

If I do go into the panel ,manufacture further, ill take note of these. The chime one is good. Environmental detection inputs? I will look into this too, CSL?

I agree and even harder getting the money to do it in the first place, only thing I can think is a bank loan? However, if it was successful, it would end very well, for person starting the company and the products being made would be better.

Thanks, making things in China would be cheaper, but making stuff here is good too, I am NO Brexiteer, but this it employs people here so that is good, but buying things from there cheaply is good. Yes, it might be hard, although I do want to start a company, could start an eBay business I guess, selling those dummy LED modules.

What else could be produced, I can see the main things needed for a panel could be injection moulding facility and a PCB manufacturing machine?

So your alarms were made in house? rather than using separate companies to make them?

Thanks for the replies, a basic design I had for a bell box was this: I would like to think that it has been designed well with encapsulated or even potted electronics, designed for any weather or condition. I could look at making a bell box or shed alarm first? Before trying a full main control panel?

Thanks for the replies, I know about all the British Standards, been looking into them and seeing what my Accenta G4 (Newest one) complies with. What features would you like? I know I would want something that has a discreet keypad which isn't ugly or big, that blends in and isn't made of cheap plastic that'll just yellow. Same for a bell box, id design an ultra slim SAB, which is made from decent plastic. Hopefully AlYeti will stumble across this post and can give me an insight into the process, who are DA?

Any Help, comments or even criticisms are appreciated. If I wanted to start a company, to put my product idea into the market, how would I go about this, employing minimal people. Please see my basic structure below.. I do have a few unique ideas, which I think would really catch on, not just panels. And, is this how companies like ADE, Texecom and Pyronix do/did it? Or was it all done in house? No separate manufacturers

Thanks, glad you like it, its a handy thing to have I am after an Accenta G4 Actually, don't have one in the collection... Although, it isn't real ADE

Thanks, I was going to start by making a key-switch panel, based around a microprocessor. I have made one around transistors before: This was on a hand etched board, that I made. I used a paint marker to draw on the tracks, for all of the components. I will have a look at the site though. I have some CMOS chips, I may use to make an alarm, to panel. I made some bell box comfort LEDs swell, this way. I like the rewarding feeling of building circuits. The circuit pictured above is. A very basic transistor latch, it would need a relay to be able to switch any decent siren on, however its correct draw is practically zero. I was thinking of trying to mimmic the Accenta's keypunches of 4 and 9 (SOS) with an Arduino, this would be a good way of testing if I can use my own. Do you know what type or brand of microprocessor is used in most alarm panels, PIC or ATMEL. I think the Accenta has a Pic Microcontrollers but not sure, the NVM chip can't be found on the G3, so it may be held in the microprocessor.

Thanks for the reply, reason for me asking all this is that I am going to have a go at building my own panel, baed around an Arduino board: https://en.wikipedia.org/wiki/Arduino I will have a look at that type of serial transmission, hopefully I can have a go at programming something to recognise it. I can see a problem with the speed and efficiency, according to my oscilloscope, when pressed, the keypad sends the data out in a burst that lasts only 24 ms in total, so very fast. Do you know if all alarm panels use this method? Or is it just ADE panels? WHere have you gotten your knowledge on this from, did you design alarm panels at one time? Thanks, Gabs

Wow, thanks for the reply, think I understand it I understand that, but still am unsure how the keypad can drop the 5v that the panel is sending it, when a button is pushed. I would have thought that the Comms was always at 0v, and would only become active with 5v when a button is pushed, the Accenta has a different Tamper loop, with the comms disconnected, but everything else left in place, none of the keypad buttons work, as it is only this line the signal is send down. I have an early Accenta LCD keypad, and it works with his panel, using exactly the same drops in voltage, so it can recognise them and then displays vague messages on the screen, not as good as the G4 one. If I was designing an alarm, I'd have made it like this, If one or 2 were pressed, then the button number would correspond with the number of 5V Square waves are sent. Can you think of any reason, the ADE didn't do it like this? Or have any alarm manufacturers done it like this? Thanks, Gabs
