Mirtone MIR2
The MIR2 allocates fixed ranges of 4-digit point IDs to all detectors, modules, and notification appliance
circuits either connected directly to the MIR2-MCM main controller module or to the MIR2-LCX
Expander module. In addition the MIR2 assigns unique point IDs to various panel faults, for example
point 0003 is assigned to Battery fault and point 0005 is assigned to Ground fault. Please refer to the
MIR2 System Operations Manual for a complete list of faults and point IDs.
No conversion is necessary for the detectors, modules, and notification appliance circuit point IDs. Those
point IDs are transmitted directly as the 4-digit SIA zone number. The MIR2 panel fault point IDs are
converted to different SIA zone numbers so there is no conflict with the SDACT’s hardwired zone
numbers.
The conversion rules are summarized in the following table:
