I had a customer a year or 2 back who wanted something for an airfield hanger. We (Knight) do door loops which stretch to 5m and he had a few of them (others may do them too !) . Don't know if this helps.

thanks for the info.

tbo, dont think i'd go down that route, did something similar once on a wicket gate. it wasnt a success..

Problem with long loops is when they fault, even using that black curly lead designed for machinery.

Old days we used to use a plug and socket, close door insert plug in the way if door opens it pulled out plug, there was also a contact on the door, and if fitted a contact on wicket gate all fed by the plug and socket. Double pole but obviously not 24 hr tampered.

I suppose today using a shunt box to bypass the tamper it could still be done, not sure if regs would be happy - one for James mrethinks .

Still say forget loops. As RF is probably being used do it that way. Less to go wrong IMHO.

tbh I'd be with you, G3 possibly is the problem.

I wonder how rubust wireless would be, never tried it in what would be a pretty hostile siuation just due to the shuttr vibration alone.

could be a problem with batteries losing connection intermittently.

You would think it would be well known if it was any good, launched over 18 months ago. Still a new one on me.

They launched that gear in security installer and we did it to death on the forums. No Thx
