I. ABOUT THE WIRELESS CO SENSOR
The Wireless Carbon Monoxide (CO) Sensor measures the amount of CO gas in the
surrounding air. The sensor returns carbon monoxide level and temperature values to the
iMonnit Online Sensor Monitoring and Notification System. The system stores both data
points in the online system where the data can be reviewed and exported as a data sheet
or graph. Notifications can be set up through the online system to alert the user when
defined CO levels have been met or exceeded.

II. ORDER OF OPERATIONS
It is important to understand the order of operations for activating your sensor. If performed
out of sequence, your sensor may have trouble communicating with iMonnit. Please
perform the steps below in the order indicated to make sure you are performing your set-up
correctly.
1. Create iMonnit Account (If new user).
2. Register all sensors and gateways to a network in iMonnit.
Sensors can only communicate with gateways on the same iMonnit
network.
3. Connect/power on gateway and wait till it checks into iMonnit.
4. Power on sensor and verify it checks into iMonnit.
We recommend powering the sensor on near the gateway then moving to the
installation location, checking signal strength along the way.
5. Configure sensor for use (This can be done at any point after step 2)
6. Install sensor in final location.
Note: Device specific setup is covered in more detail in the following
sections.
Note: For information on setting up iMonnit and the gateway refer to
the iMonnit User Guide and the gateways user guide.
PAGE 3
III. SETUP AND INSTALLATION
If this is your first time using the iMonnit online portal, you will need to create a new
account. If you have already created an account, start by logging in. For instructions on how
to register and setup your iMonnit account, please consult the iMonnit User Guide.
STEP 1: ADD DEVICE
1. Add the sensor on iMonnit.
Add the sensor to your account by choosing Sensors in the main menu.
Navigate to the Add Sensor button.
2. Find the device ID. See Figure 1.
The Device ID (ID) and Security Code
(SC) are necessary to add a sensor.
These can both be located on the label
on the side of your device.
3. Adding your device. See Figure 2.
You will need to enter the Device ID
and the Security Code from your
Sensor in the corresponding text boxes.
Use the camera on your smartphone to
scan the QR code on your device. If you
do not have a camera on your phone,
or the system is not accepting the QR
code, you may enter the Device ID
and Security Code manually.
- The Device ID is a unique number
located on each device label.
- Next, you?ll be asked to enter the Security Code from your device. A
security code consists of letters and must be entered in upper case (no
numbers). It can also be found on the barcode label of your device.
When completed, select the Add Device button.
Figure 1
Figure 2
Desktop Mobile
Select your use case. See Figure 3.
Unlike most sensors, choosing a use case in
Step 2 of adding this sensor does not give
you the option to customize your settings.
These will need to be adjusted in the settings
tab for your device. See page 9 for
instructions.
Select the Skip button when completed.
STEP 2: SETUP
Figure 3
Check your signal. See Figure 4.
The validation checklist will help you ensure your
sensor is communicating with the gateway properly
and you have a strong signal.
Checkpoint 4 will only complete when your sensor
achieves a solid connection to the gateway. Once
you insert the batteries (or flip the switch on an
industrial sensor) the sensor will communicate with
the gateway every 30 seconds for the first few
minutes.
Select the Save button when completed.
STEP 3: VALIDATION
Figure 4
STEP 4: ACTIONS
Choose your actions. See Figure 5.
Actions are the alerts that will be sent to your phone
or email in the event of an emergency. Low battery
life and device inactivity are two of the most
common actions to have enabled on your device.
See page 12 for how to set actions for your sensor.
Select the Done button when completed.

IV. SETTING UP YOUR CARBON MONOXIDE SENSOR
INSTALLING BATTERIES
ALTA commercial sensors are powered by AA batteries. Monnit encourages customers to
recycle all old batteries.
When you are finished adding the sensor to your account, the next step is to insert the
battery. The type of battery you use will depend on the category of your sensor. ALTA
Wireless CO Sensors are powered by AA batteries.
The standard version of this sensor is powered by two
replaceable 1.5 V AA sized batteries (included with
purchase). The typical battery life is up to 10 years.
This sensor is also available with a line power option.
The line powered version of this sensor has a barrel
power connector allowing it to be powered by a
standard 3.0?3.6 V power supply. The line powered
version also uses two standard 1.5 V AA batteries as
backup for uninterrupted operation in the event of line
power outage.
Power options must be selected at time of purchase,
as the internal hardware of the sensor must be
changed to support the selected power requirements.
Place batteries in the device by first taking the sensor and sliding the battery door open.
Insert fresh AA batteries in the carriage, then shut the battery door.
Complete the process by opening up iMonnit and selecting Sensors from the main
navigation menu. Verify that iMonnit is showing the sensor has a full battery level.

ANTENNA ORIENTATION
In order to get the best performance out of your ALTA Wireless Sensors, it is important to
note proper antenna orientation and sensor positioning. Antennas should all be oriented in
the same direction, pointing vertically from the sensor. If the sensor is mounted flat on its
back on a horizontal surface, you should bend the antenna as close to the sensor housing
as possible giving you the most amount of antenna pointing vertical. You should make the
antenna wire as straight as possible, avoiding any kinks and curving of the wire. Sensors
must be at least 3 ft. away from other sensors and the wireless gateway to function.

Directly under the tab bar is an overview of your sensor. This allows you to see the signal
strength and the battery level of the selected sensor. A colored dot in the left corner of the
sensor icon denotes its status.
Details View
The Details View will be the first page you see upon selecting which sensor you would like
to modify.
A. The sensor overview section will be
above every page. This will
consistently display the present
reading, signal strength, battery level,
and status.
B. The Recent Readings section
below the chart shows your most
recent data received by the sensor.
C. This graph charts how the sensor
fluctuates throughout a set date
range. To change the date range
displayed in the graph, navigate up to
the top of the Readings Chart section
on the right-hand corner to change
the from and/or to date.

Readings View
Selecting the Readings Tab within the tab bar allows you to view the sensor?s
data history as time stamped data.
- On the far right of the Sensor History Data is a cloud icon. ( ) Selecting this icon
will export an Excel file for your sensor into your download folder.
The data file will have the following fields:
MessageID: Unique identifier of the message in our database.
Sensor ID: If multiple sensors are exported, you can distinguish between the
sensors using this number ? even if the names are the same.
Sensor Name: The name you have given the sensor.
Date: The date the message was transmitted from the sensor.
Value: Data presented with transformations applied, but without additional
labels.
Formatted Value: Data transformed and presented as it is shown in the
monitoring portal.
Raw Data: Raw data as it is stored from the sensor.
Sensor State: Binary field represented as an integer containing information
about the state of the sensor when the message was transmitted. (See
?Sensor State? explained below.)
Alert Sent: Boolean indicating if this reading triggered a notification to be sent
from the system.
Sensor State
The value presented here is generated from a single byte of stored data.
A byte consists of 8 bits of data that we read as Boolean (True (1) / False (0))
fields.
When broken into individual bits, the State byte contains the following information:
aaaabcde
STS: This value is specific to the sensor profile and is often used to indicate error states
and other sensor conditions.
UNUSED: This sensor does not use these bits.
AWARE: Sensors become aware when critical sensor specific conditions are met. Going
aware can cause the sensor to trigger and report before the heartbeat and cause the
gateway to forward the data to the server immediately resulting in near immediate
transmission of the data.
TEST: This bit is active when the sensor is first powered on or reset and remains active
for the first 9 messages when using default configurations.
STS Specific Codes:
0 = No problems, sensor is functioning normally.
1 = Open circuit detected in lead.
2 = Short circuit detected in lead.
3 = Range error. Temperature is reading outside of -40 F and 257 F (-40 C and 125 C).
Note: Make sure you have the date range for the data you need input
in the ?From? and ?To? text boxes. This will be the previous day by
default. Only the first 2,500 entries in the selected date range will be
exported.

PAGE 9
Settings View
To edit the operational settings for a sensor, choose the ?Sensor? option in the main
navigation menu then select the ?Settings? tab to access the configuration page.
A. Sensor Name is a unique name you give the
sensor to easily identify it in a list and in any
notifications.
B. The Scale sets the temperature that the data
is displayed in. It will either be Fahrenheit or
Celsius.
C. Display Mode sets the display mode of the
data. Ability to set thresholds available only for
the displayed values.
D. Heartbeat Interval is how often the sensor
communicates with the gateway while in the
Aware State.
E. Aware State Heartbeat is how often the
sensor communicates with the gateway while in
the Aware state.
F. Sensor is on is the time of day the sensor is
actively working. No communication will be sent
while the sensor is hibernating.
G. Below is the minimum setting for your Carbon
Monoxide (CO) sensor. This should be set to
zero.
H. Above is the maximum allowable presence of Carbon Monoxide in the atmosphere.
I. Concentration Aware State Buffer is a buffer to prevent the sensor from bouncing
between Standard Operation and Aware State when the assessments are very close to a
threshold.
J. Time to Re-Arm is the time in seconds after triggering event that the sensor will wait
before re-arming itself.
K. Failed Transmissions before link mode is the number of transmissions the sensor
sends without response from a gateway before it goes to battery saving link mode. In link
mode, the sensor will scan for a new gateway and if not found will enter battery-saving
sleep mode for up to 60 minutes before trying to scan again. A lower number will allow
sensors to find new gateways with fewer missed readings. Higher numbers will enable the
sensor to remain with its current gateway in a noisy RF environment better. (Zero will cause
the sensor to never join another gateway to find a new gateway the battery will have to be
cycled out of the sensor.)
If the user has calibrated the sensor, the Calibrate Active field is set to False (0) and the
sensor is operating inside the Min and Max Thresholds, the bits look like 00000000, this is
represented as 0.
If the sensor is using factory calibrations and it is outside the threshold, the bit values are
00010010 and are represented as 18(16+2 because both the bit in the 16 value is set and
the bit in the 2 value is set).

The default heartbeat interval is 120 minutes or two hours. It is recommended that you do
not lower your heartbeat level too much because it will drain the battery.
Finish by selecting the Save button.
Note: Be sure to select the Save button anytime you make a change to any of
the sensor parameters. All changes made to the sensor settings will be
downloaded to the sensor on the next sensor heartbeat (check-in). Once a
change has been made and saved, you will not be able to edit that sensor?s
configuration again until it has downloaded the new setting.
Calibrate View
To calibrate a sensor, ensure that the environment of
the sensor and other calibration devices are stable.
Enter the actual (accurate) reading from the
calibration device into the text field. If you need to
change the unit of measurement you can do that
here.
Press Calibrate.
To ensure that the calibration command is received prior to the sensors next check-in,
press the control button on the back of the gateway, once, to force communication (Cellular
and Ethernet gateways).
If a sensor type has readings that need to be reset,
the ?Calibrate? tab will be available for selection in
the sensor tab bar.
After pressing the "Calibrate" button and choosing the gateway button, the server will send
the command to calibrate the specified sensor to the gateway. When the sensor checks-in,
it will send the pre-calibration reading to the gateway, then receive the calibration command
and update it?s configuration. When the process is completed, it will send a ?Calibration
Successful? message. The server will display the sensor?s last pre-calibrated reading for
this check-in, then all future readings from the sensor will be based on the new calibration
setting.
It is important to note that after calibrating the sensor, the sensor reading returned to the
server is based on pre-calibration settings. The new calibration settings will take effect on
the next sensor heartbeat.
Note: If you would like to send the changes to the sensor right away, please remove the
battery(s) for a full 60 seconds, then re-insert the battery(s). This forces the
communication from the sensor to the gateway and this the message to make a change
from the gateway back to the sensor. (If the sensors are industrial sensors, turn the
sensor off for a full minute, rather than removing the battery).
Creating a Calibration Certificate
Creating a sensor calibration certificate will mask the calibration tab from those who should
not have permissions to adjust these settings. Permissions for self-certifying a calibration
must be enabled in user permissions.
Directly below the calibrate button is the selection to "Create Calibration Certificate.
Figure 12
A. The Calibration Facility Field will be filled. Select
the dropdown menu to change your facility.
B. The ?Certificate Valid Until? field must be set
one day after the date contained in the "Date
Certified" field.
C. "Calibration Number" and "Calibration Type" are
unique values to your certificate.
D. If necessary, you can reset the heartbeat interval
here to 10 minutes, 60 minutes, or 120 minutes. By
default, this will be set to no change.
E. Choose the "Save" button before moving on.

When the new certificate is accepted, the Calibration tab will change to a Certificate tab.
You will still be able to edit the certificate by choosing the Certificate Tab and navigating
down to "Edit Calibration Certificate."
The tab will revert back to "Calibrate" after the period for the certificate ends.
Choose the text box to trigger a pop-up window allowing you to
change the scale. Select the scale you prefer and push ?Set.?
Press the ?Save? button to complete your adjustment.
Changing units here will also change units on the sensor physical display. Units changed
locally on the sensor itself will not be change this setting in iMonnit.
If the sensor settings are influenced by temperature, the scale
option will be available in the tab bar. To change the temperature
unit of measurement from Fahrenheit to Celsius or vice versa,
select the Scale tab.

VI. SECURITY
Data security and integrity is paramount at Monnit. Each layer of the system is secured
using encryption and protocols designed to protect customer data and information. The
system consists of sensor(s), gateway(s), and iMonnit software. One or more sensors
communicate with iMonnit software through a gateway.
SENSOR TO GATEWAY
Sensor and gateway radio modules are purpose built devices with proprietary unreadable
firmware, which means the sensor cannot be physically hacked or re-purposed for
malicious purposes. This adds a strong level of inherent security even before considering
encryption. Data transmission between the sensor and gateway are secured using
Encrypt-RF Security (Diffie-Hellman Key Exchange + AES-128 CBC for sensor data
messages). Beyond the encryption, data transmissions are also structurally verified and
CRC checked before they are passed up to iMonnit or down to the sensor, this ensures the
integrity of the data itself.
GATEWAY TO IMONNIT
Data transmissions between the gateway and iMonnit software are secured using 256-bit,
bank level encryption.
iMONNIT
Access is granted through the iMonnit user interface, or an Application
Programming Interface (API) safeguarded by 256-bit Transport Layer Security (TLS 1.2)
encryption. TLS is a blanket of protection to encrypt all data exchanged between iMonnit
and you. The same encryption is available to you whether you are a Basic or Premiere user
of iMonnit. You can rest assured that your data is safe with iMonnit.
SENSOR PRINTS
Sensor prints utilize a shared key between the software and the sensor to ensure that once
the data comes to iMonnit it is guaranteed to be from the device identified by the sensor
print. If this feature is purchased for the device (via iMonnit software) the devices data
becomes impossible to spoof by any malicious device.
