One of our customers moved into a house that is full of the old Grafik Eyes. Bar, kitchen, living room, etc. etc. etc. and each one has 2 keypads connected. To make things more complicated, it also has an original radio-ra system (where the FAS switch goes left to right) linked to the Grafik eyes via the GRX accessory link. I should mention I HATE HATE GRAFIK EYES, even the new ones.
Anyhoo, last week, one of these 6 zone grafik eyes died. It was a weird thing because the LED's on the grafik eye still worked as did the keypads, ie. you'd hit a button on a remote keypad and the corresponding button push would also show up on the grafik eye, but the lights would not come on. There was power however in the box and manually connecting the switch legs to the hot would turn the lights on and there were no shorts, so in my opinion it was dead. I went to disconnect it and for a second all the lights came on, but then it died again so in my now expert opinion, the unit seems to have a screw loose.
For now, I put good old fashion switches there so the customer can have lights, but I am curious what can be done here.
Is the Grafik Eye (which is at least 10 years old) really done for? There is no secret fuse or something there?
Is there any compatiblity between the old GRX grafik eyes and the new QS ones? In other words, at some point the customer will need to upgrade to either Homeworks QS or Radio RA2 and for one room, they'd kill me if I said "Hey you guys, this repair for 6 lights is going to cost you $20,000" but if they are going to spend $1000 on fixing those lights, at least it'd be nice if the repair could go towards a newer system.
also, the keypads appear to be only connected to that one Grafik Eye (I think) so it doesn't seem like they were all linked together.
