Yes I agree with the wire colour idea. We use red for powered devices, grey for phone, brown for doors, white for windows. We run 24/8, CAT3 wire to all keypads. Often the end of the keypad wire is run to the adjacent door, thus saving a brown wire run, We use the brown pair of the CAT3 for the door contact, duh! Siren, strobe get individual 18/2, with 18/3 run for power. Ground wire is present if needed, but panels are generally not grounded. Smoke and other supervisory devices get grey wires as well.
Additionally we use standard wrap around wire markers and keep track on a wirelist that is later tranferred to disk and accessible quickly from the office or my home office (thank you PC Anywhere!).
On the wirelest itself is a breif description of the location of the device. Keypads are above light switches unless otherwise noted and when used, motion detectors are in corners, hidden. Glassbreak detector locations vary so much due to different layouts, that there is little standardization, but since I purchased a digital camera, it's easy to relate the wirelist description with the picture, should there be a problem locating a wire. Since DVDs are so cheap, it's no big deal keeping lots of 1 -1.5 Mb pictures around. I have to go to each site to check the prewire anyway, so it's a good use of my time. I also take pictures of speaker prewires so it's easy to see the speaker location after drywall.
Our alarm and audio prewires are buried and this takes the drywaller out of the wire location equation. How many times have you cursed the drywaller for pulling a wire out of the wall in the wrong place? That won't happen anymore.
It is alot of work to keep accurate records, but it pays off in the long run. I don't know about anyone else, but when I sell my accounts, the paperwork and recording keeping will be hard to surpass. I've seen some real poor recording keeping as I'm sure most of you have.
Anyone ever use the inside of the can as the 'wirelist'? I took over an old PC1550 system this week that had this done. I wrote it down on my blank wirelist sheet anyway.....
Just wondering.... is it ethical to keep records, i.e. files including programming sheets and wirelests, of systems that are now monitored by others?
