I only fit wired and very rarely fit wireless
I always fit wifi comms on all my systems
Don't worry about Al yeti they are just a yeti who escaped the cage
Unfortunately Scantronic doesn't lock out the zone after it's triggered so if the device is faulty there's nothing you can do other than put your code in when it goes off or repair it
I got 24 veritas r8, 3 Scantronic 9448s, 2 accenta g4 panels, 6 galaxys, 2 ade concepts, risco lightsys, gardtec 800, 3 texecom premiers and a RSI videofied panel
so I count that as a win and reasonable pay
If you ordered it from contact orisec and they will send you a shipping label and a replacement for free and tbh if you are using the in panel receiver don't expect more than 5m range without a external antenna
