Fig. 1-7. Console and Alarms Ports Pins Order
The Alarm port contains 3 alarm inputs and 1 alarm output. The inputs accept voltage differences from
8V to 60V (indicating alarm on) or less than 8V (indicating alarm off).
The Alarm output works as follows. In an alarm situation or when the device is powered off, pin 4 (common)
is short-circuited with pin 9 (NC). When alarm is off, the pin 4 turns to a short circuit with pin 5 (NO), while pin 9
keeps isolated.
