Theenemy85 Posted April 24, 2014 Share Posted April 24, 2014 Hi, I installed a Galaxy G2+44 panel today and have just realised I forgot to install the 680Ω EOL resistor across the data line in the last Keyprox. I programmed it and everything was working fine when I left. Does anyone know how likely is it to cause me problem/callouts? Thanks Quote Link to comment Share on other sites More sharing options...
matthew.brough Posted April 24, 2014 Share Posted April 24, 2014 Depends. It is there for a reason. If passing the site I'd be inclined to pop it in. Quote www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
Theenemy85 Posted April 24, 2014 Author Share Posted April 24, 2014 Hi Matthew Thanks for your reply. What do you mean it depends? I'm not likely to be passing the site anytime soon but could make a special trip if it's likely to cause problems Quote Link to comment Share on other sites More sharing options...
goncall Posted April 24, 2014 Share Posted April 24, 2014 it won't cause any problems Quote Link to comment Share on other sites More sharing options...
matthew.brough Posted April 24, 2014 Share Posted April 24, 2014 (edited) Chances are you'll get away with it. As it is a rs485 like it should be balanced and as the eol is missing it's not but unless you get a call saying the panel is showing missing modules chances are if it's a small run dataline you'll probably get away with it. it won't cause any problemsThat isn't a guarantee although on a g2 I'd think it highly likely that he'll get away with it but to say its a dead cert would be wrong. It's there for a reason. If it wasn't necessary Honeywell wouldn't ship them with the panel.

I've seen gals wired in 8 core on long runs spurred off etc they give less data problems than belden be it with eols in the mods or not,either way if your gonna get a problem your gonna get a problem so in this case I wouldn't be rushing back to fit it Quote Link to comment Share on other sites More sharing options...

matthew.brough Posted April 24, 2014 Share Posted April 24, 2014 Irrelevant. Don't take my word for it. Use your friend google. Termination is there for a reason. Quote www.securitywarehouse.co.uk/catalog/ Link to comment Share on other sites More sharing options...
goncall Posted April 24, 2014 Share Posted April 24, 2014 Irrelevant. Don't take my word for it. Use your friend google. Termination is there for a reason. I never said it wasn't but in my experience I've seen all ways a line has been wired and all wrong and they sit happy,I've seen perfect runs in belden all terminated and problems,so in this case as the op posted I'd just wait till the next visit to fit the 680 as unlikely to be a problem which was the question,now go and play with your white elephant Quote Link to comment Share on other sites More sharing options...
matthew.brough Posted April 24, 2014 Share Posted April 24, 2014 I think you have just repeated what I suggested but I do not accept that wiring a 1/2 duplex line like a spiders web will cause no issues.

norman Posted April 24, 2014 Share Posted April 24, 2014 Data buffer, not caused issues with it missing from g2 Quote Nothing is foolproof to a sufficiently talented fool. Link to comment Share on other sites More sharing options...
james.wilson Posted April 24, 2014 Share Posted April 24, 2014 I doubt you will have an issue on a light loaded line without a termination resistor. There is one in the panel so most of the swr will be dealt with. Imo dont worry Quote securitywarehouse Security Supplies from Security Warehouse Trade Members please contact us for your TSI vetted trade discount.

Thanks Unless your data run is silly lengths then you should be fine.It's all to do with reflections causing Probs on long runs and polling.

Paul. Giles Posted April 25, 2014 Share Posted April 25, 2014 wont cause an issue, most that fit still forget to remove the jumper/cut resistor in panel when using two data lines. Honeywell never ship them with keypads or RIOs which is a shame. We do fit them but use standard alarm cable for anything under 100M now Quote Link to comment Share on other sites More sharing options...
