2.5.3. CPU OFF function (general urgency all-call) settings
(RM-200SF: DIP switch 6 operation or RM-200SA: DIP switch 5 operation)
The CPU OFF function permits the all-zone calls to be made from the RM-200SF or RM-200SA by bypassing
the CPU*

normally used by the SX-2000 system and using an analog link instead. This function is usually used
if a system failure is preventing normal broadcasts from being made. Announcement from the RM-200SF can
be made to all zones within the system only while the Talk Switch is being pressed with the CPU switch on its
top panel set to OFF, or announcement from the RM-200SA can be made to the said zones while its General
Urgency All-Call key is being held down for 4 seconds or more. Whether or not this function is available can
be set using DIP switch 6 on the bottom panel of the RM-200SF or DIP switch 5 on the side panel of the RM-
200SA. (Regarding how to make such broadcasts, see the separate Operating Instructions, "Operation.")
If the SX-2000 system receives a 24 V emergency cutoff signal*

, the general urgency all-call using the CPU
OFF function is disabled because the emergency system other than the SX-2000 system takes precedence
over the SX-2000 system.

CPU is a central processing unit, which is built in the SX-2000SM, SX-2000AI, SX-2100AI, SX-2000AO, and
SX-2100AO.

In the SX-2000 system, a 24 V emergency cutoff input terminal that allows control of an emergency audio
input is provided on the SX-2000AO's rear panel. When the SX-2000 system is combined with another
emergency system, a 24 V DC is normally kept being supplied to this 24 V emergency cutoff input terminal
and is cut off in emergency situations. This interrupts the general-purpose broadcast from the SX-2000,
allowing the emergency system other than the SX-2000 system to override it.
