24 V OUT (removable connector)
24 V dc output for logic inputs (GPI) and external equipment (I max: 800 mA).
59
DRY CONTACT (removable connector)
Dry contact that will be closed in case of a fault is detected in the main unit.
60
GPO (‘Generic Purpose Outputs’, removable connector)
10 logic outputs that are activated (the 2 pins get shorted) when paging their respective
zone or due to a GPI command.
For instance, the GPO 3 is on when paging the zone 3.
61
EXT. AMP IN (ZM 2124 only, removable connector)
Input for the connection of the external amplifier 100 V output when ZM 2124 is set to
the dual amplifier mode (through the respective dip-switch
28
).
The external amplifier is used for paging only and its input needs to be linked to the ZM

INT. AMP OUT (ZM 2124 only, removable connector)
Direct amplifier 100 / 70 V output to loudspeakers (not affected by zone selection).
Each loudspeaker shall have a line transformer with the input voltage equal to the line
voltage (70 / 100 V).
The loudspeaker total power (considering all the 6 zones) shall not be higher than the
amplifier maximum power (240 W).
