What is «Remote transmission»?
Remote transmission establishes a transmission path to the fire department in the event of a FIRE ALARM.
For FAULT there is normally a separate path established.
When does the remote transmission have to be isolated?
Normally the remote transmission operates in active stand-by. Isolation is needed only in special cases, for ex-
ample for testing the control functions. For this test the
Remote alarm isolate key
1
on the control console
has to be pressed. The «ISOLATED» state is signalled by the indicator
