I installed one of those door knox things from SytemQ a few weeks back to a new build. The thing is intermittently buzzing and of course the customer wont pay and System Q are hopeless.
I suspect the sparks have wired in my cable routes as i have even temporary lashed cables across the floor and everything appears OK. But its intermittent so how would i know. If i fail all the mains its clear but again i cant do a prolonged test so how do i know.
I asked for a second kit on supply or return to prove kit but SQ are having none of it so ive purchased a second kit and the problem persist and im stuck with kit i dont want. BTW please dont tell me i shouldn't have bought from them. Hindsight isn't going to get me paid.
Anyone any experience in sorting this problem or even how to explain to the customer whats happening?
