This is probably one for alarm engineers/sparkies familiar with this particular panel but here goes anyway. A tamper fault has developed on my system - the alarm goes off when not set (i.e. when in normal day mode). The panel only indicates "Tamper" with no zone showing unlike a real alarm when the zone lights up. It's probably a mouse chewing a cable in the loft or an insect inside a PIR, or a dying battery/wasps in the exterior bell. The panel itself has a brand new back-up battery but the exterior bell battery will be a few years old. I have put the system in Engineer mode (Day and Attack are lit). I need to trace the tamper fault or wait for my trusty installer to get back from holiday. Meanwhile, I want the whole system disabled so that no tampers arise because and I don't want it going off all night annoying my neighbours as I sometimes work nights. Will the Engineer mode setting I have described disable the system? (and can I leave it like this indefinitely whilst I check everything, which will take several days up in the loft etc?) Thanks in advance to anyone with experience of this and can advise accordingly. Cheers all.
