To connect the router to external alarm-reporting devices, attach wires to the
and relay contacts on the craft interface. A system condition that triggers
YELLOW ALARM
the red or yellow alarm LED on the craft interface also activates the corresponding alarm
relay contact.
The terminal blocks that plug into the alarm relay contacts are supplied with the router.
They accept wire of any gauge between 28-AWG and 14-AWG (0.08 and 2.08 mm
which is not provided. Use the wire gauge appropriate for the external device you are
connecting.
