I have just bought a house with a veritable alarm. I have the code for the alarm but have been told it has not been used for several years. I managed to download the manual and I have found out which rooms link to which zone however Zone 5 I am unable to find out where it is. I have done the Walk test and all the zone work 1,2,3,4,6. As soon as I go the panel and input my 4 number code, zone 5 lights up red . I then press 'part or full' and the alarm starts beeping but it doesn't stop, so it isn't setting. Don't understand why zone 5 lights up in red when I put my code in and also why system doesn't set, any help would be greatly appreciated. Thankyou
