New to the forum and desperate for help, got the wireless alarm and its worked fine for 3 months, I've got 3 PIRs and 2 contact sensors. Woke up this morning and disarmed it as usual, and set the alarm when we went out to work. When the mrs got home and opened the front door, the beeps didn't start so she assumed I never set it. A little while later one of the PIRs picked her up and the alarm went off. I got home and cleared the alarm from the panel and decided to do a walk test, but when I pressed the learn button on any of the sensors it didn't pick them up on the control panel. Tried removing the sensors with the intention of re-adding them thinking this would fix the issue but when it says press button on device to be added, I press the button and the control panel doesn't detect any of them. Tried a complete reset and still won't detect any sensors. Any idea? Thanks.
