I have moved into this house last year, and the alarm (Opt.XM6) outside security box went off automatically few times & I notice every time is was during a really sunny day like today!...I'd tried taking the battery out even swtiching the main off but it still ringing, its driving me mad...can anyone please help?

Hi Marie

No the alarm will not go off if the weather is too hot, you may have debris on you sensors which may if you like burn when it gets too hot and set of your alarm, clean all the sensors and your problem should go awat
