USER INSTRUCTIONS FOR INFILTEC LEAKAGE ANALYSIS PROGRAM

FIREDEMO.EXE is a self extracting file that
contains the DOS multi-gas program LA.COM
with sample data files for most gases.

Save the extracted files to a new folder
such as c:\firedemo on your hard drive,
or onto a floppy disk folder.  After saving
the program files, you can run the program
by going to START then RUN then C:\firedemo\LA.COM.
LA.COM is the program file.

The LA.COM program prints to DOS LPT1 printer, 
but this may not work under Windows.  To get
around this, you can select the printout option
"Print to File" and the report will be saved in
a text file so that you can use a word processing
program like MS Word to print your report.  You
will want to select a mono-spaced font like courier
for these reports, and not a proportional spaced
font, to keep the formatting of the data columns
straight.

The sample test files for each gas are adapted
from the NFPA 12A-1989 Standard Appendix B
on Integrity Testing for Halon 1301 Total
Flooding Fire Suppression Systems


       NOTE: To use this software with E3-DM4 you MUST:

       1. Set Orifice Plate Ratio=1.0 in this program
          because the DM4 computes the ratio from the Low
          Flow settings.

       2. For depressurization (fan blowing away from you) leave
          both DM4 reference ports open. Connect the signal ports
          to the fan and the door panel.

          For pressurization (fan
          blowing way from you) leave the pressure reference port
          open, but connect the flow reference port to outside/door
          pressure tap on the door with T fitting. Contect the
          signal ports to the fan and the door panel.

      If you have any questions about these two instructions,
      contact the Infiltec factory at 540-943-2776.

Improvements in 06/20/94 Version of Program LA

1. NFPA 2001-94 based calculations for gases 1301, Inergen, FM-200, FE-13 
   and NAF-SIII.
2. The graph is printed out in the report on a separate page.
3. Printer output can be written to a disk file (in ASCII format) for use in 
   word processing
4. The ESC key now allows jumping from all screens, back to the previous 
   screen.
5. Printer output has 1" margins at left and right if your printer is set to 
   10 cpi.
6. More comment lines are added to Test Identification Screen.
7. If screen entries are blank, then the lines are not printed out in report.
8. Optional upper leakage area calculation shows the effect of changing ratio 
   of upper to lower leakage.
9. Optional mixture density is computed from gas weight, room volume, and 
   site altitude.

Instructions for running Infiltec MSDOS Program LA

*  Make a copy of the program disk and store it in a safe place as a backup 
   (e.g. COPY A:*.*  B:).
*  You can copy the program disk onto your hard disk and run it from there 
   (e.g. XCOPY A:*.*  C:)
*  You must have file the LA.COM to run, plus HERC.COM if you have a mono 
   graphics monitor.
*  To run from a floppy drive, insert the disk and log onto the drive 
   (e. g. put it in drive A and get A>).
*  Type the program name, HA, and press the ENTER key to start program.
*  The first screen will ask you whether you want an "old" file with saved 
   test data or start a "new" file. 
*  If you can not read the first screen, press F1 to quit, and type LA S to 
   restart.  This will slow the display.
*  Type the letter O (for Old) to select an old file, so you can see some 
   sample data.
*  The next screen shows a directory of test files that are saved on the 
   disk such as NFPA-CAL.HAL
*  Type the first few letters (like N or NF) to select the file named 
   NFPA-CAL and then press ENTER.
*  Type Y (for Yes) when you are asked if NFPA-CAL is the file that you 
   wanted.
*  Files 1301, CO2, INERGEN, FE-13, CEA-410, NAF-SIII and FM-200 are examples.
*  File NFPA-CAL contains the NFPA 2001-94 sample calculation test data.
*  File README has information on latest updates to the program.
*    You can look through the data file you select by just pressing ENTER to 
     move through screens.
*      Or you can use the arrow, page, insert and delete keys to edit lines.
*         Or you can use the function keys to jump around or change 
          calculations:
*  F1 Key = Quit the program.  Before quitting, you will be asked if you want 
   to save your work on disk.
*  F2 Key = Change flow data input from flow units (cfm or lps) to flow 
   pressure units (in wc or Pa).
*  F3 Key = Jump ahead to the next screen.  ESC jumps you back to the 
   previous screen.
*  F4 Key = Change the measurement units from metric (Pa & lps) to English 
   (in wc & cfm) and back.
*  F5 Key = Save your work on a disk file that you can name and retrieve 
   later.
*  F6 Key = Change the calculation type from "NFPA only" to "Infiltec & NFPA" 
   and back.
*  F7 Key = Print a report of all data entered or computed up through the 
   screen you are on, or you can save the report in a disk file for your 
   word processor.

Standard Program features:

*  Data can be easily saved and retrieved from small disk files.  These 
   files have a ".HAL" extension)
*  The program works with any video board: CGA, Hercules, EGA, VGA, etc.
*  Data editing uses all the standard keys: Insert, Delete, Page, Arrows, etc.
*  Function keys are used to jump between screens and to change modes.
*  Color is used on all screens, but the program also works on monochrome or 
   LCD monitors.
*  You can switch from English to metric units (and back) by pressing key F4.  
   Note that if you save a data file, the type of units will be saved, and 
   the next time you display this data, the units will be the same as when
   you saved it.  So if you always work in one set of units, you will not
   have to switch back and fourth if you do not want to.
*  Key F6 switches you between straight NFPA 2001-94 calculations and the 
   Infiltec calculations.  Note that NFPA calculations predict the hold time 
   for 1/2 of the initial concentration (3% if you discharge 6%), while 
   Infiltec has developed a prediction of the hold time for a 1% drop in the 
   concentration (5% if you discharge 6%).  Since the Infiltec calculations 
   may be confusing to your customers who do not understand the NPFA 
   calculations, you can stay in the NFPA mode during demonstrations, and 
   then switch to the Infiltec mode when you need to have a better prediction 
   of actual discharge test results.
*  When you exit the program, you are always asked to save your data so 
   that valuable test results will not be lost.  If you were editing a 
   previous test file, you are given the option of overwriting the original 
   file or creating a new file name.
*  The program is designed to be user friendly so that it is difficult to 
   accidently make serious errors.

Please give us your suggestions for improvements and let us know about any 
   problems.
