A report for the previous job can be printed at any time.
5. Press START JOB to begin a new job. Enter a name for the new
job and then press SAVE to save the job name. The previous job
will end and a summary of it will print.
6. Check Alarm 1 & 2 setpoints (displayed in the monitor screen
window), adjust if needed.
7. Zero calibrating the unit before a new job is not required (nor
recommended). If desired, calibrate unit using ZERO
CALIBRATE menu item.
The status bar will indicate WAITING FOR PRESSURE and the
STATUS LED will flash green until containment pressure reaches the
operating window. Once this is reached, the status bar will display
NORMALand the STATUSLEDwillchange to steady green indicating
that the unit is now in its normal operational mode. Printing and
logging of pressure readings begins once the normal operational
mode is achieved.
During normal operation, the highest and lowest pressure readings
will be printed and logged into memory with a time/date stamp every
15 minutes (the default Print/Log rate).
If the monitored pressure then goes outside the operating window,
the unit will go into alarm mode. The buzzer will sound, the status
bar will change to a flashing >>ALARM<< and the STATUS LED will
flash red. The print and log rate of the pressure readings will
increase to every 15 seconds (the default Print/Log Alarm rate).

Section 4: Detailed Operation
The Omniguard 4 monitors and records the differential pressure
between the #1 inlet port and the #2 (Reference) inlet port.
In abatement applications the
Omniguard 4 should be located
outside the containment area and not in any antechambers (i.e.
shower or changing room). This allows a supervisor or hygienist to
monitor pressure readings without entering the containment area.
Work Area Setup
The Omniguard 4 should be placed on a solid (non-vibrating)
surface, excessive vibrations disrupt accurate pressure
measurement, hanging the unit on a wall is okay.
1. The intake end of the pressure tubing must be locateda minimum
of 5 feet away from any openings or HEPA fan/filter units.
Choose a location away from excessive dust or moisture.
2. Cut a 1/2”slit in the polyethylene barrier and feed approximately
1 ft. of pressure tubing through it. Tape the tubing securely to the
polyethylene.
3. Connect the free end of the tubing securely over the #1 inlet port.
Be careful not to turn the nozzle.
4. The maximum hose length is limited to 70 ft (for 3/16”ID hose).
Lengths beyond 70 ft can degrade reading accuracy.
5. The Alarm 1 and Alarm 2 settings should be in negative units
when used to monitor a negative containment area. For positive
containment applications, use positive units (Inches WC,
Millimeters WC or Pascals) for alarm setpoints.
NOTE: It is important that there be no kinks or
sharpbendsinany part of the tubing.Anyblockage
could inhibit accurate recording of the pressure
in the containment area.
Power-Up
To begin operating the Omniguard 4 , plug the power cord into a
standard wall outlet supplying 115VAC, 60Hz and press the POWER
ON/OFF key. The first time a new unit is turned on the settings will
be at default values.
Initial Power-Up -- the user is asked to set the unit’s Date & Time
and Alarm 1 & 2 setpoints because they are at the factory
defaults. This happens only until these settings are updated,
usually only the first time the unit is used.
Normal Power-Up Sequence
-- If the unit was properly turned off
after the previous usage, POWER OFF will print. Otherwise
POWER FAIL will print, indicating that an AC power failure
may have occurred. Either message will be followed by the
date and time the unit was last powered off.

A diagnostic test will automatically run and the unit will print the
date, time and the current alarm setpoints. The unit will then
immediately begin to monitor containment pressure.
Until the containment pressure has reached the operating window,
the status bar will indicate WAITING FOR PRESSURE and the
STATUS LED will flash green.
Note:Logging and printing of monitoredpressure
readings does not begin until the containment
pressure has reached the operating window!
You will need to customize the factory Alarm 1 and Alarm 2
setpoints for your application!
Once the containment pressure reaches the operating window (the
area between the Alarm 1 and Alarm 2 setpoints) the unit’s status bar
changes from WAITING FOR PRESSURE to NORMAL and the
STATUS LED changes to a steady green. NORMAL OP is then
printed along with a time-stamp. The STATUS LED changes to
orange to warn of an impending Alarm condition when the pressure
is within 0.005”WC of the Alarm setpoints.

Example of Printout after START JOB is pressed--
Alarm Condition
Once the containment pressure reaches the operating window, the
unit will be in normal operation and the alarms will be armed. Then
if containment pressure falls outside the operating window, the
following will occur:
1. Internal buzzer and AUX ALARM output will be activated and will
remain active until ALARM SILENCE is pressed.
2. The status bar will change to >>ALARM<< and begin flashing.
The STATUS LED will flash red.
3. Printer will indicate which alarm setpoint was exceeded. The

show the time followed by the current pressure reading.
When the containment pressure returns to within the normal
operating window, the unit will log and print NORMAL OP with a
time-stamp. The buzzer and AUX ALARM output will turn off. The
STATUS LED will return to a steady green. If the alarm was silenced
without rearming, it should be rearmed.
Alarm Silence, Disable and Rearming
The buzzer symbol on the Monitor Screen indicates whether the
audible alarm and AUX ALARM output are armed or disabled. The
alarm is always armed when the unit is first turned on. The alarm
silence function and AUX ALARM output are controlled by the

Print/Log Rates
The printing and logging of pressure readings begins once the unit
reaches normal operation (status bar indicates NORMAL). There are
two user-definable rates at which printing/logging occurs.
Normal Rate: (default is 15 min.)
•setting choices are 5, 15, 30 minutes or OFF.
•rate at which the highest & lowest pressure readings are
printed and logged to memory during normal operation
•when set to OFF, unit will only log & print alarm readings
Alarm Rate: (default is 15 sec.)
•setting choices are 15, 30, 60 or 120 seconds.
•rate at which pressure readings are printed and logged to
memory during an alarm condition
To change the Print/Log Rate --
1. Press MENU to view the Main Menu.
2. Highlight PRINT/LOG RATES using ▲/▼and press SELECT to
change settings.
3. Use ▲/▼to change the NORMAL RATE.

repeat step 3 to change the ALARM RATE setting.
5. Press SAVE to save the updated settings and return to the Main
Menu.
Pressing the EXIT key will return you to the Main Menu without
saving the updated settings.
To conserve paper and log space, the Alarm Print/Log rate will
reduce to 15 minutes if the unit stays in an alarm condition for more
than 10 minutes. The pressure monitoring rate is not affected. The
Alarm Print/Log rate will return to its original setting at the beginning
of the next alarm.
Inlet Pressure Response Rate
This setting determines how quickly the unit will react to pressure
changes. Reduce this setting if you are using the unit in conditions
where air pressure fluctuates rapidly and can cause false alarms,
such as in high wind.
Response Rate: (default rate is Medium)
•rate choices are Slow, Medium and Fast
•in windy conditions, set to Slow
•if quick response to small pressure changes is needed,
set to Fast
To change the Response Rate --
1. Press MENU to view the Main Menu.
