The ZOP (IED1544ZOP/IED1544ZOPC) zone output processor is a GLOBALCOM® auxiliary device for integrating line level analog devices with GLOBALCOM® Series Announcement Control Systems. The ZOP acts as a GCK endpoint to provide an I/O interface with analog audio devices using an EQ and level control.

Eight logic inputs are included for triggering actions in GCK, four of these as standard logic inputs and four as supervised inputs for detecting shorted or broken wires. The ZOP provides a redundant PoE connection that can be supplemented with an optional 12/24/48V DC auxiliary power connection for non-PoE switches.

Up to eight ambient noise sensors (IED0540S) can be connected to GCK for automatic level adjustment. Up to 2 sensors per channel can be used to adjust levels locally or on a remote T112/T112C. Using GCK, levels can automatically be adjusted higher so that audio can be heard over a louder area and lower over a quieter area.

For detecting shorted speaker lines from an amplifier, the line level inputs may be used with an end-of-line module (IED5411EOL) and indicator (IEDM596SGFI) that can be purchased separately. A fault relay on the back activates automatically when a fault is detected.

The zone output processor comes with rack mount kit PA702-RMK.
