ANY HELP IS GREATLY APPRECIATED Would anyone be able to help me in finding out how a keypad talks to the main panel, I have an oscilloscope asd I have connected it to the 'Comms' wire, when the Accenta keypad is connected to the panel. This wire is at a constant 5 volts, with dips in this voltage when a button is pressed, or the panel needs to send the keypad information. This first image shows the data line between the panel and keypad when 1 has been pressed, these dips in the 5 volt signal were created by the keypad, for the panel to recognise. The above image shows what happens when the 'PROG' key is pressed. The highlighted in red waveform is the keypad sending the Prog signal to the panel, the one in green is the panel responding to the keypad telling it to light up all LEDs. What I do not understand is how the keypad can create a dip in the 5v line if the panel is constantly giving out 5v, same with the panel, how can it then create a drop in the voltage in the data line, if the keypad is constantly giving out 5v. The only way I thought it could be done was the panel shorts out the keypads data line, and the same with the keypad, it shorts out the 5v of the keypad to create 0v in the 2 way data line. Just wondering if this is correct? If anyone knows. I have tried the sound line, however it doesn't carry any data, just 'beeps' and alarm tones.

Hi All, I hope that somebody can help me. The house we bought about 3 months ago has a G3 alarm system fitted in the understairs cupboard with an Accenta keypad in the hallway. Everything has been working fine so far but for the last few days when we put in the 4 digit code to set the alarm as we leave to go out I've noticed that the beeping (approximately every second) doesn't actually stop and when we return several hours later I can still hear it whilst I am stood outside. I have noticed that when I input the code before I leave the zone 1 led illuminates, I don't honestly know if this used to happen when the alarm was behaving normally or if this is part of the problem of the alarm not arming. I am a complete novice at this as I have never had a house with a burglar alarm before. Any tips/advice on finding a cure would be greatly appreciated.

Hello, I`m new in this site and I´m here to ask to this comunity that I have a problem with a Optima Compact G3 396. I'm teenager and my landlord doesn't remember the code and he says that he doesn´t want repair the alarm, he says just switch off, but the case that I need the alarm because I´m going to leave in a few weeks and I have got many things inside. The problem is when I switch on the alarm in the central electricity panel, it's start to sound very louder outside and inside, i´ve tried to press reset twice withing 5 sec. nothing happened, I´ve tried put ###DEFAULT CODE### as well, but nothing... I need reset this alarm, but I don´t want spend nothing... I´ve looking for engineer but they are very expensive (£65). just power light on no tamper, no attack, no day. Thank you
