Graded Door Contacts

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.

posted piccy in trade how to sort that, prefer to leave it there (in trade) if ok with all.

indeed we do fit secondary, contact just one part of a higher spec'd system.

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?

i have no issue about subject being moved to trade,

just to mention, James posted this thread, which is in public and he would know that, so i assume we are not causing any 'problem' discussing it here?

earlier i was replying using of my iphone, i find it harder to notice difference area's via board colour.

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.
