On standard SmartAlarm annunciators a fully is24VDC supply
is provided for use as a signal supply voltage.
This output is available on all +VFC terminals which are internally
linked and protected by fuse.
An internal 160mA glass quick blow fuse, 5mm x 20mm, located on the
Common Services Card is used to protect the output from field wiring
errors.
