Anyone have a setup using those components?
I'm wondering about the current calculations. The DSC 18xx PGM only supplies 300ma. COSMOD2W says [email protected] in alarm; I'm going to have 2 of them so 242ma.
The 2WTA-B specs are confusing to say the least. The 2WTA-B says 130ma "max" but 30ma in alarm and 12ma "for all other units on the loop". Somehow the "first" one on the line is 30ma and subsequent ones are 12ma. Why? The COSMO2W says 50ma "max alarm current" but 20ma "max reverse polarity current". None of this makes sense - how can max "alarm" current be more than "reverse polarity" current?
It appears I need a PC5204 power supply module. It claims 1A but down in the details for residential fire it says 550ma which just makes it.
As far as why I want to use an older panel, its for automation integration using an EnvisaLink or IT-100. (And not Elk or OPII due to wasteful cost - I already have Loxone.)
