Hello I have had a pool installed since last September & am now into my 3rd. Alarm the first one worked ok for about 2 weeks & problems ever since ie. not working or going off when no one using pool, The firm supplying ( their own alarm I think) is opperating internationally but they say they will send the electrician & he never comes! For the price paid about 440 Euros it is very poor service & I am beginning to think they dont have the answer to the problems. When the guarantee runs out I suppose one is expected to buy another alarm!!! or put up a regulation fence. Has anyone had this sort of trouble & what is the answer? horace
