The two external alarm inputs (alarm inputs #1 and #2), when activated,
are transmitted from a remote Fiber Remote Multi-IPE Interface over the
fiber-optic link to the local Fiber Remote Multi-IPE Interface to activate two
out of three external alarm outputs (alarm outputs #1 and #2) on the local
Fiber Remote Multi-IPE Interface unit. At the local site, the alarm output #3
is activated when the fiber-optic link detects an alarm condition.
The single alarm output at the remote Fiber Remote Multi-IPE Interface
will be activated if an external alarm is activated or if the fiber-optic link
detects an alarm condition.
