2.3.2. 24 v Emergency cutoff input settings (DIp switch 8 operation) (SX-2000AO only)
the 24 V Emergency cutoff input can be set to be enabled or disabled.
once enabled when the SX-2000 system is combined with an emergency broadcast system, a 24 V Dc is
normally kept being supplied to this 24 V emergency cutoff input terminal and is cut off (24 V emergency cutoff
function) in emergency situations. this interrupts the general-purpose broadcast from the SX-2000, allowing
the emergency broadcast to override it. At the same time, the EmErGENcy indicators flash, one on the
SX-2000Sm's front panel and others in the fluorescent displays on the front panels of SX-2000Aos in 24 V
emergency cutoff state.
Note
When using this input terminal in combination with an emergency broadcast system, set DIP switch 8 to oN.
Step 1. remove the protective cover on the SX-2000Ao's front panel by unscrewing it with a Phillips screwdriver.
