PMI2 Design & Engineering Considerations

The PMI-2 can be used in a project just like a PMI. Make sure that a PMI-2 is selected in the Zeus configuration. As a

result, all features and limitations currently applicable to a PMI are also applicable to a PMI-2. However, due to PMI-

2’s increased processing capability, some new enhancements have been added.

 Global PMIs in a networked FireFinder XLS system: Maximum of 10 GPMI-2 units are allowed in a Global

Voice configuration when using an NRC ring architecture. A maximum of 5 GPMI-2 units are allowed in a NIC-C

architecture. No change from PMI.

 Colors: The PMI-2 supports different colors for different event lists, with red for alarm events, yellow for

trouble events, blue for supervisory events, and magenta for security events.

 Local PMIs in a networked FireFinder XLS system: Maximum of 64 PMI-2 units are allowed in either a NIC-C or

NRC architecture. Note that the PMI only supported 59 units.

 Logic Functions: PMI-2 supports a maximum of 2500 logic functions in a single node. A AND, OR, D LATCH,

START TIMER etc are examples of logic functions. This is a marked improvement from PMI which supported only

1500 functions. Improved PMI-2 microprocessor speed combined with increased memory therefore makes it

possible to combine fire, voice and smoke control functionality in a single node.

 External References: Similar to logic functions, the maximum number of external references has also been

increased to 1000 for the PMI-2. The PMI only supported 500 external references. A logic function that

references a point physically located in a different node counts as an external reference.

 The result is that the PMI-2 supports fire events, voice evacuation, and smoke control in a single node, as long

as the logic function and external reference limits are observed.

 The supervisory current draw of the PMI-2 is 190 mA, lower than the 230 mA required for the PMI.

 Connecting cables for the PMI-2 are exactly the same as those used to connect the PMI to the rest of the

system.

 The PMI-2 supports integral Mounting slots for SCM-8 or LCM-8 modules. The PMI-2 come with two

removable cover plates below the main operator interface where the switch or LED module can be installed.

 System configurations and module firmware upgrades are transferred from a laptop computer to the PMI-2 by

a USB connection. This not only provides a faster transfer mechanism, it relieves the requirement to use a serial

connection or converter. Since many modern laptop computers do not have a serial port, this feature is a

welcome change.

 PMI-2 panel firmware is transferred from the laptop computer to the PMI-2 by an Ethernet connection. These

large system files are transferred much faster than the current serial connection, and with greater reliability.

 Global PMI database information is stored on an SD memory card instead of a PCMCIA card. Many modern

laptops do not have a port to write directly to a PCMCIA card, but may write to an SD card from a built-in port.

Also, SD cards can be inserted and removed from the card slot on the PMI-2 without removing power from the

unit. Lastly, the SD memory card slot is accessible from the back of the PMI-2 without removing the back cover

of the unit.
