arfur mo Posted September 12, 2010 Share Posted September 12, 2010 It's also effected by a magnetic field, so same as a reed for substation issue's. If a cheap prox reader could be made, perhaps reducing costs by having say 500 differs and s short range less than used fir access, there's a chance of reliable tech. TBH, i fail to see the logic of the need such high tech, no matter how advanced the contact tech used, intruder can still cut around it just as they do with 5 lever Chunb locks, or cut direct through the door, even remove complete with frame, unless anchored the best contact designed my NASA ain't going to be worth diddly squit. So you are very likely going to fit secondary detection at least (or more) anyway, logic dictates where you have a door contact ,that door contact don't ever work to protect the floors, Walls or ceilings, so why all the fuss? G3 rated villains are rated much smarter than that. Arfur If you think education is difficult, try being stupid!!!! Link to comment Share on other sites More sharing options...

arfur mo Posted September 12, 2010 Share Posted September 12, 2010 thought you could get shock c/w contact ? Thought this was trade?discussing G3 contacts I'n public did not occur - iphone skin don't dhow public, If not mods please shift ii Precisly, I'm one who don't like them mutch brigade, external influences and all that. Lace wiring would help but old hat so a dt at least would be looking a it to cover the weakness. That line of thought, the door contact serves more to indicate the doo/s are closed (if not secured) before arming. I'm not saying makers don't to strive for s better option, but in truth do we really need what we have so far the reisbility hassle and additional expense involved?

Arfur thought you could get shock c/w contact ? Viper make them, imho just asking for false alarms in the future, things like if door or window rattles in the frame during high winds.

MrHappy Posted September 12, 2010 Share Posted September 12, 2010 there only 2 post in whole thread from "non trade" members, but can't see any reason to move it ? can see any issue with a shock c/w smc , or shock + smc.....
