tcanact Posted July 2, 2019 Share Posted July 2, 2019 Hello I’ve been installing a Honeywell Galaxy G2 44+ at home recently, the system consists of 2x prox keypads & 2x Power RIO’s. The system has been running stable for a few weeks (with fire zones) and after being away for a week I thought that I’d get the intruder side configured and up and running. The day I get back from being away I come across an odd fault with one of the keypads where after going through a few menu items the keypad display goes blank momentarily, then comes back. This is followed by the first line of of display becoming a row of black squares (as pictured) If I power cycle everything this resolves the issue until they keypad is used again. They keypad then stays unusable until another power cycle. Not particularly ideal! The other keypad works fine and diags shows 100% comms. The RS485 bus is configured as follows: 680ohm EOL resistor keypad (with fault) G2-44+ keypad Power Rio Power Rio 680ohm EOL resistor System sees 6x modules. Any my ideas on what could be causing this issue? Thanks Quote Link to comment Share on other sites More sharing options...
norman Posted July 2, 2019 Share Posted July 2, 2019 Sounds like a cable issue, I'd put it on a short lead and see if it continues, or swap keypads to see if it follows the keypad or cable. 1 Quote Nothing is foolproof to a sufficiently talented fool.

GalaxyGuy Posted July 2, 2019 Share Posted July 2, 2019 Agree, swap keypads over. Looks like a faulty keypad with bars like that. Quote Link to comment Share on other sites More sharing options...

Thank you both for your input & advise, I’ll try swapping the keypad and see how I get on. I did wonder if this would be the culprit. Stuart - incidentally I also ordered a LCE from your shop last night, you may recall our various email conversations about home automation. In the end I thought I’d stick with what I had and then I can always upgrade to a GD at a later point. Quote Link to comment Share on other sites More sharing options...

datadiffusion Posted July 2, 2019 Share Posted July 2, 2019 Yep a lot of panels used to have these (expecting faults?!) and scrapped them for that reason. You can sometimes still see on the PCB where the footprint was before they changed them for standard terminals.

sixwheeledbeast Posted July 2, 2019 Share Posted July 2, 2019 Still pretty common on Honeywell stuff, makes easier for swapping out faulty stuff without re-terminating. Issue can occur if wiring is terminated without it being mounted to the board can make the insides of the terminal block twist. Quote Link to comment Share on other sites More sharing options...
