Omniguard™ 4
Section 1: Basic Care
The
Omniguard 4
is built and engineered to provide you with
dependable performance for years to come. Following these basic
guidelines will insure that you get maximum use from your unit.
Once the unit is set up, field operation is easy. Complete reports are
virtually automatic, providing the most accurate records of your job
site conditions available.
• This unit is designed to measure differential pressure only from
+0.250” to -0.250” WC (optional pressure ranges are available).
Caution: Never apply pressure to the inlet port by
mouth or with any other strong pressure device.
High pressure will permanently damage the
sensor.
• Use only
Omniguard
thermal printer paper.
• Always store the unit away from sources of excessive heat, dust
and moisture.
• Never attempt to repair any of the internal components of the
unit.
• Protect the unit from strong shocks or vibrations. Be sure the lid
is securely closed whenever transporting the unit.
• Be sure to plug your
Omniguard 4
into a power supply that
complies with the National Electrical Code. Keep all connections
dry. As with any electrical device, this unit has the potential to
cause an electrical shock hazard.
• If your unit must be shipped at any time to another location or for
service, use the original packing material and shipping box for
optimum protection during shipping.

Section 3: Quick Setup & Usage
This section is a quick reference checklist for setting up your
Omniguard 4
.
1. Insert one end of pressure tubing inside the containment area.
Connect the other end of tubing to INLET #1.
2. Locate a convenient place for
Omniguard 4
outside the
containment. Plug power cord into a power outlet.
3. Turn the unit on. If the message Set Time & Date pops up, set
the correct Time & Date. This happens if the internal battery is
has died and the built-in clock lost its settings (don’t worry, the
battery is rechargable and lasts over 30 days between charges).
4. Press PRINT JOB for a printout of the previous job, if required.
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
NORMAL and the STATUS LED will change 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).
Sample Session: Viewing/Changing Settings
1. From the Monitor Screen, press MENU to go to the Main Menu.
2. Use the ▲/▼ arrow keys to highlight ALARM SETPOINTS.
3. Press SELECT to go to the View Setting Screen and allow
changes to the ALARM SETPOINTS.
4. The ALARM 1 setting can now be increased or decreased by
using ▲/▼.

Hanging the Omniguard 4
The
Omniguard 4
can be hung on a wall for easy viewing and to keep
it off of the floor, away from possible damage. Hanging the
Omniguard
4
by the clip allows the cover to close, protecting the unit from water
damage while allowing the LCD display and STATUS LED to be
viewed through the window on the cover. The hose and AC cord
should exit the case thru the foam slot, then the cover should be
latched closed to protect the unit from water damage.
Use the DISPLAY key to flip the display orientation when hanging the
unit by its handle (see below).
Display Modes
The DISPLAY key on the
Omniguard 4
is used to vary the display
view and orientation to accomodate hanging the unit by its handle.
The pressure reading can be enlarged to enhance viewing from
across the room.

paper! Thermal paper prints on only one side, the
side away from the paper roll. If the roll is
installed incorrectly the printer will be able to

tapered point can be pulled from
the top at C.
Do not use the

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 located a 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
sharp bends in any part of the tubing. Any blockage
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.
