These settings are not included in a preset file.
● Preset
A preset is a set of parameters. Presets can be recalled from a DCP unit, a wireless DCP,
or an MCP1 unit, via GPI, from an MTX unit or MRX unit, or from MTX-MRX Editor.
Fifty presets can be stored in an MTX/MRX system.
● Emergency mode
If the “Preset” dialog box’s [Emergency Recall] setting is [ON], the MTX/MRX will
enter this mode when it receives an EMG (Emergency) signal from an external device,
or when the input to the +24V [GPI IN] pin (IN 8 for the MTX3, and IN 16 for the
MTX5-D and MRX7-D) falls below 2.5V. In this mode, the unit will operate as follows.
• The current state will be remembered. This remembered state is used to return to the
original state when the unit exits Emergency mode.
• The preset specified by the “Preset” dialog box’s [Emergency Recall] setting will be
recalled.
• Operations from an external controller such as a DCP will no longer be received. (On
the MCP1, only the utility page can be operated.)
• If [Block all paging] is selected in the “PGM1/PGX1” dialog box, the entire paging
system including the scheduler will stop.
• The unit will be taken offline from MTX-MRX Editor.
• All MTX/MRX units in the same MTX/MRX system will enter Emergency mode.
