directionally accurate.
End of Line resistor. There's an entry somewhere here on it, basically it's a resistor that you put inside your sensors to indicate that it's the last one on the circuit. It's nothing you need to worry about until you actually get the equipment. First thing you need to do is determine what you want to do and where.
I believe one of your questions was "how many 22/4 wires do I run to each room". The answer is...depends on the # and types of sensors you have. For example, in my rooms i have (and this isn't in EACH room):
1) smoke detector [needs an 18/4 run to that location]
2) motion detector [i ran 18/4 as I bought 1000' of it, 22/4 works too]
3) window contact sensors [22/2 - no power]
4) Heat [22/2 - no power needed]
5) CO [Haven't even opened up box yet, but i'd imagine it is 4-wire so in my case i ran 18/4 as i had a ton of it. I'm only doing 1 per floor]
6) Door contact sensors [22/2 - no power needed]
7) 2 Keypads, one in back of house, one in front of house. [ CAT5 ]
California requires smokes in almost every room, so i have motion & smoke everywhere. I have heat in the kitchen & laundry, and as the window sensors were priced by the dozen and were only ~$25, i bought a 12-pack. I have 15-18 windows, but i won't do every single one of them.
So to personalize this help for your situation - what do you want to put in each room? That'll tell you how many wires to run.
