3.5 ALARM Connections

A closed circuit on the ALARM input pins indicates an alarm. Pins 7 and 3 are alarm input
one. Pins 8 and 4 are alarm input two. Pins 9 and 5 are alarm input 3.
The IES-1248 signals an alarm when it detects an alarm on the ALARM input pins or the IES-
1248.
To signal an alarm, the IES-1248 opens the circuit for pins 1 and 6 (the common pin) and
closes the circuit for pins 2 and 6.
Examples of an alarm on the IES-1248 are when the IES-1248's voltage or temperature is
outside of the normal range.
