Hi all.. I am new here.. Looking to learn...I think the more I think I know,the more I realize I know so little... I came upon a very interestinginstall today.. or whats left of it. Place is in an old building undergoingextensive renovations. There is an old door that resembles something out ofa stable.. cobblestone drieway, etc.. has to be 75 years old. Some old timealarm guy looks like he protected this door by using what appears to be verysmall guage wire in a back and forth criss cross patern on the iside of thedoor. I imagine if someone kicked the door in, or maybe kicked at it fromthe outside, the line would stretch, or maybe break?? (not sure on thispart) and cause an open or closed condition. Has anyone else seen anythinglike this? I love goingi into old gun shops or jewelry shops and seeing howthe old timers did the foil on windows.. Even new systems.. I enjoywalking into a store and looking around.. wondering why they opted to go awall mount motion when a 360 ceiling mount would have been better... thentrying to figure out the logic behind the decision..

Yes, Ye Ol' Lacing.. Have done several Lacing jobs myself back in the old days when I was a tech. We still have several dozen foundries back in Indianapolis that using them. Ever heard of lacing on an addressable system :) Works better electrical devices any day!
