    External alarms are connected to the WCS using a connector inserted into the alarms port located on the rear of the WCS. The alarm connector on the WCS-4 and WCS-2 Subracks has the following inputs: four opto-isolated (chassis-ground referenced) dry contact inputs to monitor external devices. The alarm state is activated when the alarm input is pulled to ground.
  • Page 16 WCS-2 and WCS-4 Subrack Overview Before inserting the external alarms connector into the WCS alarms port, insert the conductors carrying the alarm signals into the alarm connector (circular holes). The alarm connector provides tension clamp connections in the mating connector. The wires carrying the alarm signals should be stripped back by 7mm and then inserted into the alarm connector.
