I'm putting together my first Elk M1 system having used HAI previously.
The Current Draw Worksheet that Elk has is telling me our system needs 15.66 amps.
This is quite a bit more than most people here seem to have, Altronix doesn't even offer a power supply that can supply that much.
The biggest draws are 11 COSMO-4W smoke/co detectors at .40mA each, combustible gas sensors at .8mA each, and assorted other sensors that have a max draw of nearly an amp each.
It is apparently unwise to have several parallel power supplies in parallel because they can fight each other, or overload one the others if one fails.
I could use dedicated power supplies for some purposes, such as one for the smoke circuit, another for glass breaks, another for sirens, etc.
There are also some lab power supplies available that offer up to 30A at 12VDC such as this one on Amazon.
Is there a better way? How have others solved this problem?
