Matt Eaton Posted November 19, 2015 Posted November 19, 2015 Hi. I'm living at my Nans house. She has not used the alarm for about 5 years. I tried to set the alarm yesterday with what I thought was the code, however the internal alarm went mad and also the alarm on the keypad went mad. I could not stop it so I had to cut the cable from the keypad to the control panel. I rewired the broken cable but the keypad is dead, the pirs are all lit up. When I connected the live wire to the keypad it makes a very light ticking noise but no lights on the panel. Any ideas...please. Thanks Quote

norman Posted November 20, 2015 Posted November 20, 2015 Not necessarily, there could be a few more reasons too and if the battery is really old the charging circuit may be damaged. Quote Nothing is foolproof to a sufficiently talented fool.

Thanks Nope, the keypad was never designed to be disconnected on a live panel, and I'd bet the NVM is corrupted, as it often is on this model. It's a 9800 / 9800+ by the way, 9827 refers only to the keypad itself. Quote So, I've decided to take my work back underground.... to stop it falling into the wrong hands
sixwheeledbeast Posted November 20, 2015 Posted November 20, 2015 It's 20 years old and most likely never been serviced in years get the system decommissioned or upgraded. Quote
