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
