How many is "many" though?  What sort of numbers are we talking about RTS?

Greetings,
on average  each install uses  3 digital keypads, 1 zone expander, 3 dual
tech motion detectors (with LED displayed), 5 glass breakage detectors, 4
doors, 1 high power siren, 2 low power sirens, wireless key entry, cellular
backup transmitter.
again on average  current  runs in the 800 - 900 ma range..   in alarm  it
can jump up to 1.5 - 2 amp..

Back in the days of Moose, Adcor, E.L. and early Ademco  the power was a no
brainer,  they offered 1 to 2 amp  standard..
But with each new and improved panel  the current supply drops ..

It seems the industry  is pushing toward wireless,  for good or other..
