My alarm just sounded itself in the middle of the night which was nice.I shut it down with my code but now it will not do anything on the keypad and the attack light is showing.I have tried to power it off but nothing clears it.I know the egineer who put this in put his own codes in and keeps charging us £40 to come out everytime the alarm comes up for a service by showing the flashing tamper.All he does is keys his code in and clears it then trots of £40 richer.He would be hanged in the days of Robin Hood for this.I would be greatful if anyone can tell me how to clear this 1st problem to get my alarm to function right and also if there is a way to clear his rip off codes off as well.In the time Ive had the alarm I could have bought a new system and swapped it all over myself as Im not bad with electical things and he could be told to sod off as he has made a fortune of me.Many thanks in advance or your help
