Hanging the Omniguard
The Omniguard can be hung on a wall for easy viewing and to keep it
off of the floor, away from possible damage. Hanging the Omniguard
by the clip allows the cover to close, protecting the unit from water
damage while allowing the monitoring screen to be viewed through
the window on the cover. The pressure tubing and AC cord should exit
the case thru the foam slot, then the cover should be latched closed
to protect the unit from damage.
Caution: Only hang the Omniguard from a sturdy hook. A
fall could damage the unit and disrupt accurate pressure
measurements.
Loading the Thermal Printer Paper
Caution : Only use Omniguard thermal printer paper!
Thermal paper prints on one side only. If the paper roll
is installed incorrectly, the printer will be able to advance
the paper but will not be able to print on it.
1. Remove the paper lid and
thumbscrew. Cut the end of the
paper to a tapered point.
2. Place the paper roll, marked A,
into the paper lid so the paper
unrolls from the bottom.
3. Insert the tapered point of the
paper into the front panel slot
marked B, feed through the
printer until tapered point can be
pulled from the top of the front
panel at slot marked C.
Do not use the Paper Feed
function to advance the
paper.
4. From C, gently pull the paper until
the tapered portion is completely
exposed.
5. Replace the paper lid onto the
front panel and secure with the
thumbscrew.

Section 4: Detailed Operation
The Omniguard monitors and records (logs) the differential pressure
between the nozzle and the nozzle (Reference).
In abatement applications, the Omniguard 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 (see Appendix C for more details)
The Omniguard should be placed on a solid (non-vibrating) surface,
excessive vibrations disrupt accurate pressure measurement.
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 nozzle.
Be careful not to turn the nozzle.
4. Route the tubing and AC cord through the foam notch area on
the upper right corner of the case. Close the lid to protect the
Omniguard from damage, (be careful to not pinch the tubing or
AC cord).
5. The maximum hose length is limited to 70 ft (for 3/16”ID hose).
Lengths beyond 70 ft can degrade reading accuracy.
Caution: 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 use the Omniguard, plug the power cord into a standard wall outlet
providing 115-230 VAC, 50-60 Hz and press the power button.
The first time that a new Omniguard is turned on, the settings will be
at default values.
Initial Power-Up
Note: The first time the Omniguard is turned on, the
touchscreen will need to calibrated. The screen will
display a small box with an X in the middle of it. Touch
the X and continue until the calibration is completed.
Touchscreen calibration will need to be done if the
Omniguard is reset to factory default settings.

Page 10 Omniguard Cellular™ Owner’s Manual Page 11
Engineering Solutions Inc
A quick start tutorial will explain how to use the touchscreen.
Touch anywhere on the screen to go to tutorial screen 2. Touch
the icon to exit the tutorial and go to the Home Screen.
Set the Time & Date and Alarm 1 & Alarm 2 settings because
they are set at the factory defaults. The Time & Date will only
need to be set once. The Alarm 1 & Alarm 2 settings may need
to be adjusted for each Job’s requirements. For asbestos
removal, the Alarm 1 & Alarm 2 settings should be in negative
units when used to monitor a negative (vacuum) containment
area. For positive pressure applications, use positive units for
the Alarm settings.
Note: The Alarm 1 & 2 settings and the Time & Date
are displayed in yellow on the Home screen until
they have been changed from factory defaults.
Normal Power-Up Sequence
A diagnostic test will automatically run and the Omniguard will then
immediately begin to monitor containment pressure. The status will
indicate START JOB. Touch START JOB to begin actively monitoring
a new job.
Note: If the Omniguard was actively monitoring a Job when
it was turned off, it will automatically resume monitoring the
current Job. POWER OFF followed by the time-stamp will
print. Otherwise AC MODE or POWER FAIL will print,
indicating that an AC power failure occurred. Either message
will be followed by the time-stamp.
Once the Omniguard is actively monitoring a Job, the status will
indicate WAITING FOR PRESSURE until the containment pressure
has reached the operating window. The Job Name, time-stamp and
Alarm settings will be printed.
Note: Logging and printing of monitored pressure readings
does not begin until the containment pressure has reached the
operating window and the status indicates NORMAL.
Reminder: Be sure the Alarm 1 and Alarm 2 settings are
correct for your job site requirements!
Once the containment pressure reaches the operating window (the
area between the Alarm 1 and Alarm 2 settings) the status changes
from WAITING FOR PRESSURE to NORMAL and a green border
will appear around the screen. NORMAL OP is then printed along
with a time-stamp.
The screen border will change from green to yellow and the status
changes to APPROACHING ALARM to warn of an impending
Alarm condition when the pressure is within 0.005”WC of the Alarm
settings.
Starting/Ending A Job
Pressing START JOB will not erase any previous job logs, nor will it
alter any other settings (such as the Alarm settings). The log for the
previous job can be printed at any time.
Note: It is a good idea to print a report of the previous
job before starting a new job. A report for the previous
job may be printed at a later time by touching on
the Home screen, choose the report you want and touch
Print.
To start a new job --
1. If the Omniguard is not currently monitoring a job, the status will
indicate START JOB at the bottom of the Home screen. Touch
START JOB, then confirm you want to start a new job.
2. Enter the new Job Name, then touch to save it and start
monitoring. The Job Name, time-stamp and current alarm settings
will be logged and printed.
To end the current job --
1. From the Home screen, touch in the upper left-hand corner
to go to the Main menu.
2. From the Main Menu, touch End Job, then confirm you want to
end the job by touching End Job again.

USB Flash Drive – Data Collection
The upper USB port on the Omniguard allows a Supervisor to gather
Job Logs at the job site using a USB Flash Drive. The logs can be
viewed later on a PC using the Omniguard Communication software
available free @ www.Omniguard.com.
Transferring the Job Logs to a USB Flash Drive
The Job Logs stored in the Omniguard’s memory are copied as a
single Log file to a USB Flash Drive. The Omniguard Communication
software can read the Log file and separate it back into individual Job
Logs for storage on your PC. Each time a USB Flash Drive is inserted
into an Omniguard, all Job Logs are copied to the drive.
To transfer Job Logs --
1. The Omniguard must be turned on and displaying the current
pressure (at Home screen).
2. Plug the USB Flash Drive into the upper USB port on the
Omniguard. The flash drive icon should appear and the Omniguard
will automatically begin to download all job logs. This could take
several minutes before completing.
3. When the transfer is complete the screen will show the name of the
new Log file created on the flash drive. The file name will consist
of the last 6 digits of the Omniguard serial number followed by a
letter. Each file also has the time & date it was copied onto the
flash drive.
Example: If the Omniguard 5 serial number is
G506932, the fi rst Log fi le will be 506932.OGL. The
second fi le will be 506932A.OGL, the third fi le will be
506932B.OGL, etcetera. The Log fi les are stored in
the folder OMNIGUARD in the sub-folder LOGS.
To complete the transfer to the PC, insert the USB Flash Drive into
an open USB port on the PC. Using the Omniguard Communication
software, select “Open Log...” from the “File” menu. Navigate to the
USB Flash Drive, select the “OMNIGUAR\LOGS” folder and open
the appropriate Log file.
Message Rate
The Message Rate setting is the minimum amount of time the
Telephone Autodialer or Cellular Wireless Modem must wait between
multiple alarms before dialing or sending an new alert message in
response to a new alarm condition. This setting is to prevent multiple
alert messages from being when the job site is experiencing rapid
alarm occurrences due to windy (or other) conditions.
The setting can only be viewed and changed when a USB Port Adapter
is connected to an Omniguard.

Remote Auxiliary Alarm
The Remote Auxiliary Alarm is a combination high-intensity strobe
light and 95db audible alarm on a 25 foot cable that connects to the
Omniguard USB connector using the optional USB Port Adapter. The
Remote Auxiliary Alarm plugs into the Aux Alarm port on the USB
Port Adapter which in turn is connected to the USB port using the
USB cable (included with the Omniguard).
In an alarm condition, the Remote Auxiliary Alarm will activate. It may
be muted by touching the icon. The Remote Auxiliary Alarm will
only re-arm once the unit has returned to normal operation.
Telephone Autodialer
The Telephone Autodialer is supplied with a 25 foot cable that connects
to the Omniguard USB port using the optional USB Port Adapter. The
Telephone Autodialer plugs into the Autodialer port on the USB Port
Adapter which in turn is connected to the USB port using the USB
cable (included with the Omniguard). The Autodialer also requires a
working land line telephone connection box with an RJ11 jack.
In an alarm condition, the Autodialer will call the pre-programmed
phone numbers (up to 4) and play a pre-recorded message alerting
the off-site personnel of an alarm condition at the job site.
The Autodialer only activates once in a given time period (5, 10 or 15
minutes – the Message Rate setting). This prevents the Autodialer
from calling more than once if there are multiple alarms occurring
within a short period of time. After the 5, 10 or 15 minute period has
elapsed, the Autodialer will dial out again if the unit is still in an alarm
condition or when the next alarm condition occurs.
Cellular Wireless Modem for non-Verizon Wireless
NetworksBy using the optional Cellular Wireless Modem and USB
Port Adapter, the Omniguard Cellular can access cellular wireless
networks other than Verizon to automatically send alarm and job
reports to cell phones and email accounts. In addition, the Omniguard
can respond to requests for information from wireless cell phones
and via e-mail.
Wireless communication requires a specially configured MultiTech
MultiModem cellular wireless modem. This modem is similar to a
cell phone. It has a phone number and requires an active cell phone
account with SMS texting support, using either a traditional plan with
monthly payments or a prepaid plan. Contact Engineering Solutions
for more information on acquiring a cellular wireless modem.

Master Cell Phone Numbers –
Two cell phone numbers can be programmed directly into the
Omniguard. A text message will be sent to each phone number when
the Omniguard enters Normal operation and when an Alarm condition
occurs. The Message Rate setting determines the minimum time
between Alarm notification messages, this is to prevent frequent
messages if the unit is going in and out of the Alarm condition.
Phone numbers programmed directly into the Omniguard will also
receive a Daily Summary report, indicating how long the Omniguard
was in Normal operation, the number of alarms and the total time the
unit was in the Alarm condition. The Daily Summary is sent at 5:30pm
each day unless a Notify List has been selected (see below).
Notify Lists –
In addition to the two Master Cell Phone Numbers, the Omniguard can
also send alerts to personnel contained in a Notify List. The Omniguard
can store up to four Notify Lists, only one can be active at a time.
A Notify List contains a list of wireless phone numbers and e-mail
addresses for a specific group of off-site personnel. Each Notify List
allows different phone numbers and/or e-mail addresses for Alarm
and Normal Operation notification and for Reports. The Lists also
allow the report notification time to be changed.
Notify Lists can only be created and programmed into
the Omniguard using the Omniguard Communications
PC software. See the Help that comes with the
software for more information on setting up Notify
Lists.
Request Job Site Status via Cell Phone or E-mail –
It is possible to request status information from an Omniguard
connected to a cellular wireless modem. A text message or e-mail is
sent to the Omniguard which replies with the report type requested.
The available reports include a Daily Summary, overall Job Summary,
Current Status and Settings.
To get a complete list of reports the Omniguard can provide send a text
message or e-mail with a “0” (zero) in the body of the message.
Text messages sent to the Omniguard must be in
the “short message” (SMS) format and are sent to
the phone number of the wireless modem. E-mail
messages sent to the Omniguard must be in plain
text format and should be sent to the e-mail address
provided by the wireless service provider. The
message format is shown below, where “nnnnnnnnnn”
is the 10-digit phone number of the cellular modem,
with area code first (no hypens or spaces).

Problem: OMNIGUARD status does not indicate NORMAL
operation when turned on, and does not print.
Solution: For normal operation, the monitored pressure must be
between the Alarm 1 and Alarm 2 settings. When the Omniguard is
first turned on, the containment pressure will not likely be between
the Alarm 1 & 2 settings, and the Omniguard will not log or print the
pressure readings. The Omniguard will begin logging and printing
the pressure readings only after the containment pressure has
reached the Normal operating window.

Problem: The unit does not display the proper pressure.
Solution: Check to see that the tubing is connected properly to the
top nozzle. The bottom nozzle should not be connected.
Solution: Make sure that the tubing does not have a kink or a sharp
bend.
Solution: Make sure that you are using the correct 3/16” ID tubing
size, and the end of the tubing on the inlet nozzle is not worn. If
it is worn or loose, cut off 1” of the tube using a sharp knife and
reinsert on the inlet nozzle.
Solution: Make sure that the tubing connection into the containment
area is properly placed and secured as described in Section 4:
Work Area Setup.
Problem: Excessive momentary alarms.
Solution: Adjust Alarm 1 &2 settings to allow for normal air pressure
fluctuations caused by entries into work area or other equipment.
Make sure that you are within the minimum negative air pressure
requirements.
Remedy: If you suspect that wind may be causing rapid pressure
fluctuations, reduce the setting for Response Rate (see Section
4: Detailed Operation).
Problem: Printer is not working properly or a paper jam occurs.
Solution: The icon indicates printer is disabled. Turn On the printer
by touching the icon and then touching Off.
Solution: The icon indicates printer is disabled because Omniguard

Engineering Solutions Inc
Appendix C: Establishing a Containment Site
The Omniguard monitors and records the differential pressure
between the top inlet nozzle and the bottom inlet nozzle
(Reference).
In abatement applications the Omniguard 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.
This section of general guidelines to establishing a containment
site is provided by Engineering Solutions Inc for informational
purposes only. Engineering Solutions Inc is not responsible for
its accuracy nor conformance with specific regulations for your
area. Engineering Solutions Inc specifically advises all users
to obtain the advice of qualified professionals for each use and
application of the Omniguard. Engineering Solutions Inc makes
no claims as to the proper usage or interpretation of the data
provided by the Omniguard.
General Guidelines to Establishing a Containment Site
1. The contractor and hygienist are to be certified prior to qualifying
to bid on an abatement job.
2. All workers are to have undergone specific training in abatement
procedures.
3. Typical abatement requirements:
a. Containment area to be sealed within a double layer of
8 mil plastic or equivalent.
b. Before beginning work within the containment area and at
the beginning of each shift, the containment area must be
inspected for breaches and smoke-tested for leaks, and
any leaks sealed.
c. Air volume within containment must be changed 4 times
per hour, i.e. the entire air volume must be evacuated
every 15 minutes.
d. Minimum pressure in containment is -0.020”WC, i.e. the
differential pressure between containment pressure and
ambient/outside pressure must be at least -0.020”WC as
measured by a manometer.
e. The containment area must be kept under negative pressure
throughout the period of its use.
f. Air movement must be directed away from employees within
containment and toward a HEPA filtration unit.
g. Fiber levels within the containment area must be sampled
at a specific interval and be less than a proscribed level,
i.e. sampled 1 time a day or more and fiber levels below
“5 fibers/100 fields”.

4. Calculating site airflow requirements:
A typical heavy duty HEPA fan/filter unit has a 1000 CFM (cubic
feet per minute) capacity with a new filter. Units are typically
derated by 25%, so a 1000 CFM unit is derated to 750 CFM by
the hygienists when calculating actual site airflow requirements.
Example #1: A room measuring 20 x 20 ft with a 10 ft ceiling
encloses 4000 CF of air. To meet the 4X per hour change
rate the fan/filter unit must be capable of pulling 267 CFM
of air (4000 x 4/60) from the containment area and maintain
a minimum negative pressure of -0.020”WC.
Example #2: Room size is 20 x 50 with 12 ft ceiling. Requires
(20 x 50 x 12) CF x 4 / 60 = 800 CFM or 2 units (of a 1000
CFM fan/filter unit... remember the fan/filter unit is derated
to 750 CFM).
Example #3: Room size is 100 x 100 with 16 ft ceiling.
Requires (100 x 100 x 16) CF x 4 / 60 = 10667 CFM or
15 fan/filter units (of a 1000 CFM unit).
5. The containment area pressure should be monitored at various
points to confirm adherence to abatement requirements.
Remember that air is a medium, and air pressure is not identical
throughout the containment area. The pressures at specific
locations within the containment area vary due to distance, room
temperature, proximity to openings, room geometry, etc. Typically
one manometer is used for every two “rooms” that have a doorway
and attached hallway, up to 1000 square ft.
5. Using a manometer that provides highly accurate pressure
readings, time stamped logging of all readings, and audible alarm
and printouts of all logged readings protects workers and the
public from accidental exposure to airborne hazards and provides
proof of containment to protect employers from environmental
contamination lawsuits
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.
