Alarm Connector (RJ45)
External devices can be connected to the alarm port to either trigger an alarm event or to be the recipient of an alarm
event triggered by the Switch. External device connections can be paired together and connected to the alarm port
using a standard RJ45 connector. As with any RJ45 connector, there are four pairs of copper wires that can be used,
two pairs for external input connections like temperature sensors and two pairs for external output connections like
speakers or LED lights.

The alarm input pin-pairs, pair1 (Din1+/Din1-) and pair2 (Din2+/Din2-), are used to send alarm signals to the CPU of
the Switch. When the circuit between Din+ and Din- is shorted, an alarm signal will be sent to the CPU.
The alarm output pin-pairs, pair1 (Common1/Normal open1) and pair2 (Common2/Normal open2), are controlled by
the CPU of the Switch and are used to send alarm signals to external devices. When the circuit between the Common
and Normal is open, 42 VAC 50 Hz, 60 VDC, 1 A current is sent. The CPU can short this circuit when an alarm event
occurs.
