Missing the point….. again

PP8FR Reverse Powered

In the out

A customer from WA found this in the course of his travels. Once again a separate fire trip relay has been mistakenly used! To make things worse the power has been fed into the expansion outputs rather than the dedicated inputs. This will work however it makes things harder for the tech who has had to change all the output jumpers to get one of the boards to work on fire trip.

Remember technicians, the whole point of the PP8FR is to provide a built in/all in one fire trip and power distribution solution. No extra relay is required. Also read the instructions!

Care when terminating.

Recently one of my re-sellers had to rush to site with a replacement module for a PP8FR that had a “faulty” output. Fuse one would blow every time power was applied to the board.

On inspection I removed the main output terminal plug and found a single strand off copper shorting the output. I brushed it off and the unit worked like new.

It is sometimes easier to terminate to the main output plug while removed from the PP8FR. In this case while striping/cutting the cables the tech had inadvertently dropped strands of copper onto the board and one got stuck behind the replaced plug. A simple enough mistake to make and a good reminder to take care when terminating around exposed electronics. If the copper had fallen on a controller the cost could have been considerable.
