drewn Posted September 14, 2017 Share Posted September 14, 2017 Hi guys, Has anyone out there installed and used the Heathcote Electronics IRDOT-P unit? Seems a good way to alternate train running but I'm wondering if there are any down sides . Drew Link to post Share on other sites More sharing options...
Matt Posted September 14, 2017 Share Posted September 14, 2017 Not this one but used their mas sequencer for signals which has same inbuilt detector. Great little units. Only issue I could see would be if installed on a low level hiddwn fy as the sensors would get tricked by upper level (I tried install under a bridge and has this problem). As standard the detector is directly soldered to the circuit board which I found fiddly to retrofit. Latterly I requested detectors on a wiring loom which is much easier and I think no cost extra.

RMweb Gold Tony Teague Posted September 15, 2017 RMweb Gold Share Posted September 15, 2017 I don't have any IRDOT-P units installed but I do have around 80 other IRDOT units installed and working, plus my first Heathcote uncoupler unit and I can happily recommend their products (no connection etc). I have a semi-automated fiddle yard in which the rear trains move up when the front ones are released; about 20 of these roads are just 2 trains long, but I have recently converted 2 roads to "light engine" roads and one holds 6 locos whilst the other holds 9. Once the first loco is released the others each move up in turn after a short delay (these are based on IRDOT-2D units); it all works very well. I have solved the problem that Matt mentions, in that I have two fiddle yards that are underneath other structures and in these cases I have painted the underside of the boards above with dark brown matt emulsion paint which does not reflect, and so the IRDOT units work perfectly. I can't see any reason why an IRDOT-P would not work as well as their other units do. Tony Link to post Share on other sites More sharing options...
