Hi everyone can I get some help please?
One of my pir sensors was faulty would randomly go off in the night, so I stupidly decided to change it myself with a new D20 one, I wired it up accordingly and now I noticed that non of the sensors in the house have the red led motion light blinking anymore, when I input the alarm code in the separate panel now all the zone lights light up red and it makes the beeping noise but the alarm won't set anymore. I've tried looking online but can not find anything, please help!
