II. SENSOR SECURITY
The ALTA Wireless Water Detection Disk has been designed and built to securely manage data from sensors monitoring your
environment and equipment. Hacking from botnets are in the headlines, Monnit
®
Corporation has taken extreme measures
to ensure your data security is handled with the utmost care and attention to detail. The same methods utilized by financial
institutions to transmit data are also used in Monnit security infrastructure. Security features of the gateway include tamper
proof network interfaces, data encryption, and bank-grade security.
Monnit?s proprietary sensor protocol uses low transmit power and specialized radio equipment to transmit application data.
Wireless devices listening on open communication protocols cannot eavesdrop on sensors. Packet level encryption and
verification is key to ensuring traffic isn?t altered between sensors and gateways. Paired with a best-in-class range and
power consumption protocol, all data is transmitted securely from your devices. Thereby ensuring a smooth, worry-free,
experience.
PAGE 2
DISC COMMUNICATION SECURITY
The sensor and gateway generate a secure, wireless tunnel , Encrypt-RF?, between the two devices using ECDH-256
(Elliptic Curve Diffie-Hellman) public key exchange to generate a unique symmetric key between each pair of devices.
Sensors and gateways use this link-specific key to process packet level data with hardware-accelerated, 128-bit AES
(Advanced Encryption Standard) encryption, which minimizes power consumption to provide the industry's best battery life.
Thanks to this combination, Monnit proudly offers robust bank-grade security at every level.

SensorPrints
TM
is the industry's only end-to-end Internet of Things (IoT) data authentication platform for low-power
wireless sensors. SensorPrints authenticates data by issuing a unique fingerprint for each device within the IoT. Data is
secured from the point of generation to the point of consumption. Easy to install and use, SensorPrints is the definitive IoT
security solution for any enterprise.
SensorPrints authenticates data at both the point of generation and consumption, creating trust between the sensor and
server levels. Implementing 256-bit SHA 3 authentication, SensorPrints creates a fingerprint for a Monnit Wireless Sensor
that contains an authenticated sensor message. When data is transmitted from the sensor, it is accompanied by a generated
authentication token. Upon receipt by the application, the token is evaluated via a cryptographic hash function against a
unique per-sensor secret key. This step provides unprecedented full-coverage security for any Monnit user wishing to secure
their IoT devices and data.

OPTIONAL DATA AUTHENTICATION
PAGE 3
iMONNIT SECURITY
iMonnit is the online software and central hub for configuring your device settings. All data is secured on dedicated servers
operating Microsoft SQL Server. 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 that
encrypts all data exchanged between iMonnit and you. The same encryption is available to you whether you are a basic user
or a premiere user of iMonnit. You can rest assured that your data is safe with iMonnit.
DATA SECURITY ON THE GATEWAY
The ALTA gateways are designed to prevent prying eyes from accessing the data that is stored on the sensors. Gateways do
not run on an off-the-shelf, multi-function OS (operating system). Instead, they run a purpose-specific, real-time, embedded
state machine that cannot be hacked to run malicious processes. There are also no active interface listeners that can be used
to gain access to the device over the network. The fortified gateway secures your data from attackers and secures the
gateway from becoming a relay for malicious programs.
SET-UP STEPS
PAGE 4
It is important to understand the order of operations for activating your ALTA Water Detection Disk. If done out of order,
your sensor may have trouble communicating with iMonnit. Please consult the steps below to make sure you are performing
your setup correctly.
III. ORDER OF OPERATIONS FOR ACTIVATION
Your gateway must be registered first to verify communication between the device and iMonnit. Any sensors or meters you
wish to add onto your network must come after the gateway.
2. Register your gateway on iMonnit, or other software, then power it up.
After you?ve registered your gateway, it?s time to add your Water Detection Disk to the iMonnit account.
3. Register your ALTA Water Detection Disk on iMonnit, power it up, and verify it checks into the gateway
and software.
Please refer to the ALTA Quick Start Guide for additional
information about sensor configuration.
Please refer to the gateway's user guide for more information
relating to gateway setup procedures.
a. iMonnit Premier
b. iMonnit Enterprise
c. iMonnit Express
d. iMonnit Mine
1. Set up the Monnit Software of your choice. (Create an account if this the first time.)
Please refer to the appropriate software documentation
for more information.
Note: ALTA Sensors will perform a handshake when powered up during which the sensor will send 10 transmissions 30
seconds apart before engaging the configured interval or Heartbeat.
Place your sensor in the spot where water detection functionality is desired. Make sure you have the correct antenna
orientation to receive a strong signal.
Each of these steps are covered in more detail in the following sections.
4. Place the Water Detection Disk in a location to detect water.
PAGE 5

scan the QR codes on your sensor and gateway. For detailed instructions on how to install the iMonnit Mobile App, please
visit the Monnit knowledge base article entitled: How to Install the iMonnit Mobile App, online.
DISC PLACEMENT
Place each Water Detection Disc within 1,200 feet of an ALTA Gateway. Water Detection Discs should be installed to avoid
transmissions through a lot of metal or concrete and repositioned to avoid such obstacles if radio communication is spotty. A
Water Detection Disc should also be placed at least one foot from the gateway and other sensors.
ALTA Water Detection Discs should NOT be placed where they can be exposed to volatile or flammable gas. A Water
Detection Disc should be deployed where it will be protected from operating temperatures outside those disclosed in the
data sheet. Water Detection Discs aren't recommended for use in fridges and freezers, even though they may be deployed in
a refrigerator or freezer. However, the wireless range of the sensor will be significantly reduced.
Since the electronics of an are sealed within the sensor housing, the On/Off/Status button is there for your convenience. If
you aren't using the sensor, leave the button in the Off position to preserve battery life.
Water Detection Discs are designed for wet environments and environments with fluctuating or excessive humidity.
However, they are not designed to be exposed to corrosive or deoxidizing gas or vapor (e.g., chlorine gas, hydrogen sulfide
gas, ammonia gas, sulfuric acid gas, nitric oxide gas, etc.). Water Detection Discs also should not be placed in: places with salt
water, oils, chemical liquids, or organic solvents; low- or high-pressure environments; areas with powerful vibrations; or in
other places where similar hazards exist.
Water Detection Discs are weather-tight, may be deployed both outdoors and indoors. The enclosure of the industrial sensor
protects against falling dirt, wind-blown dust, rain, sleet, snow, splashing water, and hose-directed water. The Water
Detection Disc also remains undamaged by ice formation.
WARNING: In placing the Water Detection Disc be aware that it has a mechanical impact rating of IK06, meaning
that the housing protects the sensor from a mechanical impact of one Joule. This is roughly equivalent to dropping a
solid metal sphere weighing 500 grams from 20 centimeters onto the respective housing.
Water Detection Discs aren't rated for greater mechanical impact based on a documented Risk Analysis performed
by Monnit. Therefore, the IK06 rating is justified because the sensors should be:
- Installed in locations that unauthorized persons or the general public cannot easily access
- Accessed during normal use for occasional operations such as adjustment, programming, or maintenance
We recommend adhering to these stipulations because using the sensors in a manner inconsistent with the above
may impair their IK06 protection.
PAGE 6
CLEANING
When needed, clean the sensor with a damp, but not dripping-wet, cloth where it's installed. Do not use cleaners or
chemicals.
PAGE 7
BUTTON AND LED BEHAVIOR
The Water Detection Disc has a button on the top that is used to control the behavior of the disc. This button can be used to
turn the disc on, turn the disc off and manually have the disc take and report a measurement.
V. USING THE WATER DETECTION DISC
Press and hold the button until the LED turns GREEN. When the
Device first turns on, the LED will flash GREEN four times and
then remain GREEN for one second. If the Water Detection Disc
is able to successfully connect to a gateway, the LED will flash
green two times. If the disc is unable to connect to a gateway
within 25 seconds, the LED will flash RED two times.
Turning the Disc ON
Press and hold the button until the LED turns GREEN. Once the
LED is GREEN, release the button. The disc will then detect the
presence or absence of water and send a data message to the
gateway. If no connection to the gateway has been made, when
the button is pressed, the LED will first flash RED for 125 ms and
then turn green. If the button is released while the LED remains
GREEN, the disc will then try and connect to a gateway and send
a data message.
Sending a Data Message
Press and hold the button for 5 seconds until the LED flashes RED four times and then remains RED. Once the LED turns
RED the device will power off as soon as the button is released.
Turning the Disc OFF

PAGE 11
Selecting the ?History? tab within the tab bar allows you to view the sensor?s data history as time stamped data.
History View
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.
- SensorID: If multiple sensors are exported you can distinguish which reading was from which using this number even
if the names for some reason 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.

2,500 entries in the selected date range will be exported.
PAGE 12
- Battery: Estimated life remaining of the battery.
- Raw Data: Raw data as it is stored from the sensor.
- Sensor State: Binary field represented as an integer containing information about the state or the sensor when the
message was transmitted. (See ?Sensor State Explained? below).
- Gateway ID: The Identifier of the gateway that relayed the data from the sensor.
- Alert Sent: Boolean indicating if this reading triggered a notification to be sent from the system.
- Signal Strength: Strength of communication signal between the sensor and the gateway, shown as percentage value.
- Voltage: Actual voltage measured at the sensor battery used to calculate battery percent-age, similar to Received
Signal you can use one or the other or both if they help you.
Note on Sensor State: The value presented here is generated from a single byte of stored data. A byte consists of eight bits of
data that we read as Boolean (True (1)/False (0)) fields.
Using a temperature sensor as an example: If the sensor is using factory calibrations, the Calibrate Active field is set as True
(1) so the bit values are 00010000 and it is represented as 16.
If the sensor is outside the Min or Max threshold, the Aware State is set as True (1) so the bit values are 00000010 and it is
represented as 2.
If the sensor has just been powered on or reset for any reason, the Test bit is set as True (1) so the bit values are 00000001
and it is represented as 1.
If the user has calibrated the sensor, this field, the Calibrate Active field, is set as False AND the sensor is operating inside the
Min and Max Thresholds, the bits look like 00000000 this is represented as 0.

C. Aware State Heartbeat is how often the sensor
communicates with the gateway while in an Aware State.
D. Enter aware state when water is field allows you to set
whether you want to be alerted when water is either
Present, Absent, or when there is a State Change.
E. Time to Re-Arm is the time in seconds after a triggering
event that the sensor will wait before re-arming itself.
F. In small sensor networks (less than seven sensors), the
sensors can be set to Synchronize their communications.
The default setting "Off" allows the sensors to randomize
their communications, therefore maximizing communication
robustness. Setting this setting to "On" will synchronize the
communication of the sensors.
A
B
G. Failed transmissions before link mode is the number of transmissions the sensor sends without a 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, it
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. (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.)
