ALARM Connector Pin Layout 

A closed circuit on the 

ALARM

 input pins indicates an alarm.

• Pins 1 and 9 are alarm input one.

• Pins 2 and 10 are alarm input two.

• Pins 3 and 11 are alarm input three.

The IES-6000 signals an alarm when it detects an alarm on the 

ALARM

 input pins, the IES-

6000 is overheated, the voltage readings are outside the tolerance levels, a fan fails, or another 
alarm occurs.

To signal a minor alarm, the MSC opens the circuit for pins 4 and 12 and closes the circuit for 
pins 5 and 12.

To signal a major alarm, the MSC opens the circuit for pins 13 and 6 and closes the circuit for 
pins 14 and 6.

To signal a critical alarm, the MSC opens the circuit for pins 7 and 15 and closes the circuit for 
pins 8 and 15.
