Welcome to the forum.
It sounds as though you're ready to tackle this project. You said:
I'm not sure if once the wires are all in place if it's as simple as following Ken_In_Pittsburgh's instructions and use the keypad to start programming the system. Is it really just that simple??
The truth is that once all of the wires, sensors, etc. are in place, the only remaining task is programming. But that's not to say it's simple. The difficulty of programming will depend largely upon your learning style and how you approach things. Most of your questions can be answered by studying the Install Manual and the Reference Manual, along with our FAQ's and tutorials. You don't need a computer or software, although it can be done that way. If all installations were identical, it would be very easy to give you a step-by-step, foolproof programming sequence. But every house and family are unique; the difficulty, then, is not so much in learning how
to program as in what
to program so the system works the way you need it to work.
I'll take a stab at your initial questions and trust that you'll make every effort to learn as much on your own as you can.
First, the wiring really isn't that involved. You're correct: AC for power from the transformer, Bell for the siren. AUX provides auxiliary power; that is, power for motion detectors, glass breaks, etc. (any device that needs power to operate).
RED, BLK, YEL, GRN is the keybus, a color-coded interface for conecting keypads, modules (like the wireless receiver), and pretty much any device that must communicate with the system by sending and receiving data
, rather than simple electrical current.
The Z and COM terminals are where the zones are connected.
PGM's are programmable terminals that will either complete or break a circuit when certain events occur, depending upon how you program them.
All that's left are the four telephone terminals.
It's really not all that different from your 1555!
CAT5 is suitable electrically
, but it's physically very fragile and is therefore not recommended for alarm use.
Resistors are used to supervise the wiring. Click here
for an article on the use of resistors. (The link is not working properly, so you'll have to scroll down after going to that page.)
See if that gets you started.
