Something wierds going on

[Emokid1994]

hello
I have a scantronic 9100 alarm and for the past month the alarm has gone of twice both those days were Saturday's and both were 11:35 at night and it was always zone 3 which is the kitchen motion detector, something seems very strange about this and I don't know why there is nothing in the detector and it's clean and sea
End with blu tack, Any ideas what I could of been?
Thanks in advance

Mains surge ? Something switching on at that time ? Fit filters and check battery

Thanks,
The battery is not very old at all however we have had the ELCB tripping at about 6 in the morning some mornings, there's a substation next to the house of that makes a difference and I can't think of anything coming on at that time, I am thinking it might be paranormal or a dodgy detector

Had a job that was tripping a detector most days around 1.30 pm did all the normal things replaced detector , swopped power and alarm pairs , even sat in house at 1.30 with alarm set ! In the end fitted act 1313 spike filter and mains filter been ok since...

Ok thanks I will keep an eye on it and I'm fitting the menvier speech dialler tomorrow so I should know when we go on holiday on Saturday if it's gone off, I might buy a filter for it soon if it doesn't stop

I concur - The ACT1313 is the aspirin/paracetamol of alarm systems. If anything wierd happens, fit one.
