Note:
If a power transformer must be shared between EX-2 modules
(an example would be at the FSCS), the +VA rating on output is
0.6 VA. This is enough to run any LED or sonalent provided on
the FSCS. A maximum of 10 VA would be available to run other
items. (All LEDs and sonic alerts are On during the LED test.)
