Thank you for your help, I will order a battery for the alarm, and hopefully that will make it work. I have a code which I would like to change to my own, since the keys on the keypad have all worn off, around the old code. Thanks everybody for your help, If it doesn't work after that, or continues to buzz very loudly, I'll call a local alarm company, how much would a service cost? roughly.

Problem is, I'm a student, and I really cannot afford it, not even £50 for a new alarm, I just wanted to know more about it, so then I'll be able to use it, for piece of mind.

Good to know it is serviceable, I see, well, my parents have an Optima XM from the early 1990s, it gets used every day, is that made by ADE too? Just thinking about it there, and from memory, the XM case and the Concept case seem to be the same. What sort of battery do these alarms take? 9v? I'll have a go at changing the battery myself, it can't be that hard, surely. Well, it was a guess that the external sounder is dead, but by the looks of it, it is dead, what is the little bit of circuit board in it, connected to the siren? Does this also have a battery that needs changing? Oh, yes, I have herd of Honeywell, they make thermostats and the like, would what looks like an Accenta work with the Concept main panel? It was also make by ADE, from what I can see on Google.

Hi, thanks for replying to my post. Is that old for a burglar alarm? the Keypad is a little yellowed, I guess that is the UV from the sun reacting with the plastic. I was wondering about a new panel because I have read on another forum, DIY NOT that they were cheap junk, so I was just curious. The main control box is very hot, towards the top right, and has left black heat marks on the wall above it, which worried me. Do ADE still make this alarm? The box outside is totally dead, it has 4 vents each side, and a big hole in it, you can see what looks like a small circuit board, and a big black siren horn thing. I am guessing the box is dead and beyond repair

Hi, I'm new here, so please bear with me I have just moved into a house with an Concept System alarm, I know nothing about alarms, so could anyone tell me: How old it is? How much electricity do alarms use? Would it be worth getting the system removed? Who made the Concept System? And are there any spares, incase it is old and things go wrong? The keypad just says 'DAY' and 'POWER', the main box which says Concept System on it, it has a 'POWER' light on too, it makes a quiet buzzing sound, is this normal? Thanks in advance
