OK Newbie here at installing home alarms and now I need some advise. I bought and installed a vista 20P setup and now I am ready to install 3 smokes and 2 heat detectors. Currently, all my zones are wired and everything works. Here is what I have wired and installed so far:
3 PIR's (LED enabled)
6160 keypad
WAVE2 siren
2---eight zone hardwired expansion modules (for expansion flexibility should I need it at a later date)
I have the 1.2 aux power supply and matching transformer but it is not hooked up yet.
The smokes are the 2-wire photoelectric with thermal and the heat detectors are 135 degree.
My question is, when I install the 3 smokes PLUS the 2 heat detectors on Zone 1 (with the EOL resistor), will the panel power supply handle everything? I know the max is 500mA but I don't know if I should calculate the power draw on the smokes and heats and add to the other stuff. I read that the wave 2 draws 500mA itself but something tells me that that is seperate being that it is hooked to a set of dedicated terminals (#4&5??)
According to the specs, the two zone expanders draw 60mA together, the three PIR will draw 30mA together, the keypad is 40/150 and the smokes say 50/130 each. How do I do an accurate load calculation assuming all smokes and 2 heat detectors are used? Do I need a sperate battery for the power supply as well? If i need the Auxillary supply, can I just power the smokes and heats from that and let the panel power everything else?
Sorry for the long post but I am confused and I can't find any real clear references anywhere!
Thanks guys....

Look carefully at the specs for the 2-wire smokes. That standby power is 50 micro amps. The 130 milliamp draw in alarm is the one you need to take into account. (the first number is standby, the second number is alarm load).
Heats draw no power, they are a normally open contact device (basically a fancy switch).
As you sit, you are still good for power consumption, but since you have the power supply, install it, and get it out of the way.
