Approx 10 years ago I installed a Galaxy G2-20 with multiple DO8M contacts at my house and it has been working fine since.
Recently I have a strange problem where I originally thought the D08M sensor was defective so I changed the zone to not used like I have done in the past. I also removed the serial number in the RF options but when I take the alarm out of installor mode it fails on zone sabotage while nothing is configured.
Im not a specialist and I cannot find back my notes so some help is much appreciated! ?
