5 Installation Checklist

NoWire installation requires the following items:

5.1 Required items included

• NoWire 1100 with internal receiver.

• Power supply: 12VDC, 500mA Class II.

• Small flat head screw driver for NoWire terminal blocks and transmitter terminal block

connections.

5.2 Items sold separately

• EN1501 pulse transmitters or EN1210 universal transmitters for wireless points.

• Outdoor enclosures to house the transmitters.

• Meters with digital pulsers.

5.3 Hardware you must provide

• Low voltage wiring (telephone, cat5 or thermostat wire) for connection from your meters to the

transmitters, from the meters to the wired pulse inputs of NoWire, and from the pulse outputs to your input equipment.

• RS485/RS232 compatible cabling for connection to Com2 Modbus serial port or terminal block

connection.

• Mounting screws for attaching NoWire enclosure to a flat surface.

• ½” conduit and conduit fittings connecting into NoWire.

• Any additional tools required for the installation.

6 Installation Instructions

6.1 Mount the NoWire enclosure

• Here are some items to consider when deciding where to permanently locate the NoWire

enclosure.

o Place where it will be easy to view the NoWire LCD display. o NoWire is outdoor rated if proper watertight conduit connections are used. o Locate out of direct sunlight to avoid exceeding the maximum temperature rating.

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 9

NoWire Model 2100 Installation and Operation Manual

o Locate near a 120V outlet where the NoWire power supply will be plugged in. o Allow room for conduit bends and runs that connect to the bottom of the NoWire

enclosure. (if required for application)

o Locate away from other equipment per your local electrical codes. o Locate in an area that allows for optimal wireless communications from the meter

transmitters. Though the wireless communications was designed for use inside of buildings with obstacles and such it is best to avoid mounting NoWire in enclosed rooms that have metal or thick rebar reinforced concrete walls or deep down in sub-basements far away from the transmitters that need to be seen by it. If this is unavoidable then you may need an external receiver (NoWire 1100-2) that can be mounted in an optimal location connected to NoWire up to 50 feet away. Repeaters may also be used in this situation. See the Wireless Theory of Operation section.

• Remove the NoWire cover by unscrewing the 4 corner screws on the cover.

• Note the deep channels in the corners of the enclosure that have a 1/8” hole at the bottom.

This is where mounting screws are inserted. These do not need to be water tight since they are outside the front cover gasket.

• Using the appropriate mounting screws for your location, attach the NoWire enclosure to your

flat surface.

• If you wish to use conduit for routing your NoWire wiring, you may remove the wire fitting on

the bottom of the NoWire enclosure and attach a ½” conduit. Use a water tight fitting if you need to keep NoWire water tight.

6.2 Attach optional external wiring to NoWire

6.2.1 Wired Pulse Inputs

If you are using wired pulse inputs to directly connect your meters then wire the pulse output wires from the meters into terminals P1 through P4 utilizing the PG terminals as the common ground reference point. See [link] for more details on wired pulse inputs.

6.2.2 Wired Pulse Outputs

If you are using the pulse outputs to connect to external equipment do the following: For pulse output #1 wire the 1+ terminal to the positive signal of your equipment and the 1- terminal to the negative or ground reference signal of your equipment. For pulse output 2 through 4 wire to terminals 2+/ 2-, 3+/ 3-, and 4+/ 4- respectively.

6.2.3 RS232/RS485 Connections

If you are communicating with NoWire using Modbus connect using RS232 or half duplex multi-drop RS485. For RS232 connections connect your RS232 cable to NoWire COM2 DB9 female connector. For RS485 either connect to D+, D-, and GND on the NoWire terminal block or connect to pin 1 (D+), pin 9 (D-) and pin 5 (GND) to NoWire COM2 DB9 female connector.

6.2.4 Apply Power to NoWire

NoWire comes with a 12VDC power supply. Before plugging the power supply into a 120V outlet, route the power supply wire up thru the NoWire wire entry location on the bottom of the enclosure and connect the wires to the V+ and V- terminal block on the bottom left side of the NoWire circuit board. Be sure the positive wire is connected to V+ and the negative wire is connected to V-. The + and – designations should be shown on the power supply itself or the power supply wires. Once your power

8.2 Wireless System

8.2.1 Wireless hardware

NoWire utilizes the Inovonics Echostream wireless equipment for its wireless communication backbone. Since 1986, Inovonics Wireless has shipped almost two million Radio Frequency (RF) products. Inovonics has been a pioneer and a leader in the field of wireless signal/control and voice communications. Inovonics developed the TapWatch® submetering system based upon their field proven wireless security systems and has been the leading wireless submetering system since it was introduced in early 1998.

8.2.2 How the wireless communication works

The system works in the unlicensed wireless spectrum of 902-928 MHz which is the same as many cordless telephones, security systems, wireless modems, etc. Specifically it uses a frequency hopping spread spectrum strategy. An Inovonics Wireless battery operated transmitter is installed on each meter that provides a dry or electronic contact pulse output. The transmitter sends a data packet about once an hour broadcasting its unique transmitter number, the current count of pulses gathered from the meter, and any other special information. The other information is data like a low battery or to inform that someone has opened the cover of the transmitter (called a tamper). The transmitter is low powered so the battery will last a long time (up to 8 years).

Since the transmitters have limited range and there can be environmental barriers to radio frequency transmission, NoWire with its receiver may not be able to hear the transmission of data. To allow for this, Inovonics wireless repeaters are installed at key locations on the site. The repeaters are higher powered than transmitters and are connected to AC power. They take valid transmissions and repeat them at high power so the NoWire receiver can hear the message. Multiple repeaters may be used to relay the message to the NoWire receiver. NoWire collects the messages, deletes any duplicate ones, stores, and processes them to display meter readings.

8.2.3 Basics of Radio Frequency (RF)

It is necessary for installers to understand the basics of radio frequency and the types of environmental factors that can result in the NoWire system not working or performing at peak efficiency.

8.2.3.1 Radio Frequency in General

Radio Frequency is electrical energy that is conducted through the air. It requires a transmitter to send the information, and a receiver with antennas that receive the information. Antennas either radiate (emit) a signal, or receive a signal, or they can do both. The electricity that is sent through the air has a frequency. It looks like a wave. As the wave goes further and further from its sending antenna, the signal propagates and becomes weaker.

8.2.3.2 Frequency Spectrum

NoWire wireless communications use the unlicensed frequency, 902- 928 MHz, the same frequencies as are used by some cordless telephones, security systems, and other miscellaneous devices. The

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 17

NoWire Model 2100 Installation and Operation Manual

frequencies that are used for RF transmission are regulated by the government. In the United States, the FCC (Federal Communications Commission) decides who is able to use which frequencies and for which purposes, and it issues licenses for specific frequencies for specific functions (like radio stations, TV stations, cell phones, etc.) In the U.S., there are a few frequencies called the unlicensed spectrum which anyone is allowed to use within certain limits. No end user license is required to use products using these frequencies. Devices using these frequencies are restricted in power so they don’t interfere with other devices using this same part of the spectrum. (For example, these are the frequencies many of us use for cordless telephones in our homes.)

8.2.3.3 RF Factors That Will Affect NoWire communications

The amount of transmission power is a factor in how far away the signal can be heard. As RF leaves a transmitting antenna, signal strength decreases as the distance from the transmitter increases. Radio signals can be affected by atmospheric conditions resulting in phenomena called fades and multipath. Both fade and multipath can result in a particular frequency not transmitting efficiently at a given place at a given time. In other works, it could be present one minute and gone the next for one frequency at one place. Radio signals can bounce or be reflected off objects, or be absorbed by some objects. Some materials affect RF more than others. Many, but not all, of the materials used in building construction and landscaping will affect how RF works.

As stated, some materials allow RF to pass through, some materials block or disperse the radio waves, and yet other materials absorb the radio waves. For example:

• Wood, sheet rock, plain glass, usually let the RF pass.

• Metal, metal studs, stucco with wire mesh, chain link fencing, plaster with wire mesh, concrete

with wire mesh, solar panels, metal satellite dishes, cinder block can interfere with RF. Because

of RF interference, DO NOT INSTALL transmitters or repeaters on metal siding, inside of metal

boxes, on the surface of metal boxes, or in metal lined rooms like walk-in coolers or freezers.

• Some modern windows with built in resistance to solar gain use materials which may interfere

with RF.

• Vegetation can interfere with RF. The transmission environment changes when leaves are on

the trees and when they have fallen off.

• Hills and earthen berms can absorb or deflect a lot of RF. Try to minimize the number of

obstacles between the transmitters and repeaters or the NoWire receiver.

• Auto and truck traffic. If there is a busy road or a truck parking lot between transmitter and

repeater, the signals may at times bounce off the vehicles.

• People usually don’t bother RF from passing.

Frequency Hopping:

8.2.3.4 Frequency Hopping

The wireless system has been designed to effectively deal with RF blocking. Since the transmitters are mandated to be low powered, the transmission environment constantly changes, and barriers come and go, not all of the transmissions from the transmitters may be received at the NoWire receiver. To counteract these effects, the NoWire system uses a technique called frequency hopping. This means that messages are sent more than once on separate frequencies. Frequency hopping is also known as spread spectrum. In the following illustration, narrowband means that the signal is sent over one frequency. In spread spectrum, the same message is sent over multiple frequencies.

NoWire location

8.2.4 Wireless System Planning

You must determine if NoWire will need repeaters to get the transmitter signals to be received by the NoWire receiver. For smaller installations you may not need repeaters if the transmitters are within a few hundred feet of the NoWire receiver or even further if there are few or no obstacles. For larger spread out installations you will need to determine where repeaters need to be placed. Here is an example of a multi-family property with marked repeater locations.

8.2.4.1 Determine if repeaters are necessary

To determine if repeaters are necessary you may utilize NoWire with an EN1501 transmitter in fast mode. By moving the EN1501 transmitter around to your meter locations while transmitting in fast mode you may read the transmitter signal level to determine first if it is seen by NoWire and, if so, is the signal level strong enough.

• Locate NoWire where it will be installed and apply power.

• Using the setup menus assign an EN1501 transmitter to a wireless input point if not already

assigned.

• Open the EN1501 case and press the tamper spring down 3 times within 10 seconds. This will

put it in fast mode and transmit once every minute. The transmitter will stay in fast mode for 3

days, or until the reset button is pressed. NoWire will display a status code of “F” when it

detects the transmitter in fast mode.

• Locate the transmitter in the desired test location.

• Using the setup menus for the assigned wireless input point scroll to the “Xmitter Rcvd” setup

screen. This will indicate the date and time it last received a transmission. This will

automatically update with each reception of a message from the transmitter. Stay on this

screen for a few minutes and verify the transmitter message is received every minute.

• Continue to scroll through the setup menus to the “Xmitr Levels” setup screen. If the Level is

greater than 4 then the signal is strong enough. Note: You may wish to stay on this screen for a

while until the Level value settles to its final value. If it was strong when it was first received

then it may take some time before the true level is established.

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 20

NoWire Model 2100 Installation and Operation Manual

• If you determine the message is not being received or the level is not high enough then you may

place your repeater in your desired location and perform the test again to verify you are now

receiving messages from the transmitter. Note: Repeaters are 4 or 5 times more powerful than

transmitters allowing for further distances from NoWire than transmitters.

8.3 The Installation Process

8.3.1 Project Coordination

Project coordination for a large installation usually includes:

• Designing the repeater backbone, if needed, and determine the most efficient repeater

locations.

• Working with the property owner to determine the location for NoWire and associated power.

• Determining if repeaters are required and will be installed indoors or outdoors.

• Working with the property owner to have AC power installed at the repeater locations. NOTE:

Repeaters ship with a 14 VAC transformer that connects to a 110 VAC outlet.

• Verifying that all transmitters and repeaters are assigned to NoWire and labeling each with their

installation location.

• Working up an installation plan with the property owner so installers have access to the

transmitter and repeater locations.

• Supervising the installation of all the components.

• Acting as the single point of contact for the property owner.

Because an installation on an existing site (called a retrofit) can be disruptive to the tenants and the property manager, it is necessary to make the whole process as professional and efficient as possible and all of the installers need to be sensitive to both groups. If the NoWire system is being installed in new construction, there should be no impact on tenants.

8.3.2 Install NoWire

Please see the Installation Instructions section earlier in this manual for installing the NoWire enclosure.

8.3.3 Assign the wireless transmitters

Following the instructions in the Setup Menus Operation section earlier in this manual assign each transmitter to a wireless input point. Label each transmitter with its point number or location description so you keep them identified. Assign them in the order in which you want their meter readings to be displayed.

8.3.4 Install the transmitters

The transmitters are small devices that are battery powered. They are intended to be mounted indoors only unless housed in an outdoor enclosure sold separately.

8.3.4.1 Pre-installation

• Inspect the installation l Before starting to install transmitters, look around at the location for

the best place to install a transmitter. Consider these environmental factors.

o Heat. Even though the transmitters will operate continuously between 32 to 140

degrees Fahrenheit, the longest battery life will occur between 70-90 degrees

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 21

NoWire Model 2100 Installation and Operation Manual

Fahrenheit. The typical closets or cabinets where this device is installed have poor ventilation and often shares the space with water heaters and other heat producing equipment. The temperature can go up dramatically when the doors are closed. If the transmitter is inside a closet with louvered doors, make sure the louvers aren’t all plugged up and air can flow freely.

o Humidity. The transmitters must be installed in a non-condensing environment. Watch

for water puddles on the floor, on top of water heaters, etc. as these may indicate leaks or other problems that require the attention of the property manager. Also look for condensation (or sweating”) above the mounting location of the transmitter. In humid environments, cold water pipes, air exchange units and air conditioners will sweat and drops of water will fall to the floor. Do not mount the transmitter on or under anything with potential to sweat and drip water on the transmitter. If the location where the transmitter will be installed is a place where there is a potential for flooding (such as a basement apartment, in the same room as a water heater, etc.), mount the transmitter high.

o Building construction. Consider the effects of building materials on RF. Are there metal

studs? Are the walls built of stucco with wire mesh inside? Are there steel boxes, sheet metal air exchange units or metal ductwork that could cause problems the RF signal? If you run into an unusual situation, give us a call. Installations have been successfully done in these types of environments however additional RF knowledge and tools are needed.

o Line of sight. Although it is not technically a requirement to be within line of sight,

consider what is between the transmitter and the repeater or the NoWire receiver. Is there a lot of concrete and steel construction? Are there earthen berms or hills? Are there a lot of trees (this may not always be evident in the months when leaves have fallen)? If there is any way to do it, mount the transmitter where it won’t be affected by these elements. Mount the transmitter as high as possible. If there is any suspicion that the location of the transmitter may be a problem, you may require a repeaters in the area to get the RF level to an acceptable stength.

o Installation in Closets. In an apartment environment, the utility meters are often

installed in closets. Sometimes, the meters are in closets that are also in use by the tenants. If the installation location is a closet, take extra care to robustly mount the transmitter in a location where it will not be bumped or knocked off the wall or covered with RF blocking agents like foil Christmas wrap.

o Don’t block the Meter Face. When installed, the RF transmitter must not prevent the

visual reading of the meter register.

• Verify you have the correct transmitter for the apartment. It is extremely important to put the

right transmitter in the right apartment so the customer gets billed correctly.

• Verify you can mount the transmitter to the wall, to the piping, or to the meter. The

manufacturer, type of meter used and the pulser wire (supplied by the meter manufacturer) will

determine where the transmitter can be installed. The preferred installation is to screw mount

the transmitter to a safe wall location or wire-tie it to the piping. If it is installed on a wall, it

should be mounted within 10 feet of the meter (closer is always better).

8.3.4.2 Mounting the transmitter

The following installation instructions are guidelines. No two installations are alike. Some installations may require some departure from standard procedures so good judgment is the best guide. In most cases, wall or pipe mounting is desirable. Some of the pulser wires are only 6 inches long so the only

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 22

NoWire Model 2100 Installation and Operation Manual

alternative may be to attach the transmitter to the meter itself using double sided tape. If this is the case, extra care must be taken to keep the transmitter above or on the side of the meter to avoid condensation or any chance of getting standing water in the housing. Some manufacturers have optional longer cords or give instructions on how to build longer cords. Double sided tape in certain environments is not as reliable for adhering to the wall as is using a mounting screw. The transmitter could easily fall in to a place that prevents the RF from being heard. Adhesives can lose effectiveness over time, especially in hot environments like water heater closets. If tape is to be used, make sure the mounting surface is clean and dry.

BEFORE DRILLING, ALWAYS BE CERTAIN YOU CAN DO SO SAFELY AND WITHOUT CAUSING DAMAGE. MAKE SURE YOU WILL NOT BE DRILLING INTO WATER PIPES, SEWER PIPES, GAS LINES, ELECTRICAL WIRES, AND ELECTRICAL BOXES OR THROUGH THE WALL.

NOTE: Some meters are polarity sensitive, meaning there are specific positive and negative terminals. The wiring must be terminated correctly inside the transmitter. Failure to cable it correctly can cause the transmitter to be destroyed. If you do not know whether or not the meter you are installing to is polarity sensitive, contact Submeter Solutions for guidance.

• Remove the cover from the transmitter. To open the housing, press down on the base tab near

the cabling through hole while lifting away the cover. Properly opening the transmitter housing

will not damage the housing.

CAUTION: Inside the casing are some electronic components that have adjustment screws.

Under no circumstance should you touch these screws. They can only be adjusted at the factory.

• Using a small flat-bladed screwdriver, carefully remove the battery. The mounting hole is behind

it. You may also slide a wire-tie thru the mounting holes.

• Mount the transmitter in the predetermined safe location using a mounting screw, wire-tie or

some other hardware (as required). If you are mounting this to sheet rock, always use an anchor

so it is secure and will not get pulled down. Make sure the thru-hole is pointing in the desired

direction. One screw is usually sufficient.

• Reinsert the battery.

• Press the reset button on the transmitter.

NoWire Model 2100 Installation and Operation Manual

8.3.4.3 Connecting the transmitter to the meter

The cable between the transmitter and the meter may be manufactured for the specific meter and should be with the meter already or the installer should have been given a supply of them. Measure out enough wire to connect the meter to the transmitter with enough length to properly “dress” the cabling.

• Strip the two wires at the transmitter end. About 1/8 inch is sufficient.

• Remove the blue terminal block by pulling it up off the two pins.

• Loosen the two screws in the terminal block.

• Put the two ends of the stripped wire into the terminal block and tighten the screws.

• If the wiring from the meter is “polarized” (meaning one wire must be wired only to a negative

terminal, the other only to a positive terminal), the negative connection is the terminal closest

to the edge of the transmitter board.

• Guiding the cable through the thru-hole in the housing, secure the terminal block to the

terminals by pressing the terminal block down on the two pins.

• Dress and staple the cabling.

• Connect the meter end of the cable to the meter. Specific instructions may apply. Consult the

meter manufacturer for specific information on how to connect to the meter pulser.

8.3.4.4 Initialize the transmitter

• Make a notation of the meter reading from the meter face. Be sure to note which location the

reading is for. This information can be entered in the NoWire setup menu for the wireless input

point.

• PRESS THE RESET BUTTON. This resets the transmitter count to zero.

• Put the cover back on the casing.

NoWire Model 2100 Installation and Operation Manual

11 NoWire 2100 Specifics

11.1 Features different from NoWire 1100

Following are the features and descriptions of how NoWire 2100 differs from NoWire 1100.

11.1.1 Ethernet and Wifi

Ethernet and Wifi are built in to the hardware.

• Truly plug and play to upload data to the cloud when you plug in an active Internet connection.

• If you set your Wifi credentials (SSID & password) it will also utilize your Wifi connection for data

upload.

• No need to select between Ethernet and Wifi. If you have your Wifi credentials configured it

will switch between Ethernet and Wifi if the Ethernet connection has problems. Similarly if your

Wifi connection has problems it will switch to the Ethernet connection. It will keep switching to

the other until a good Internet connection is established.

11.1.2 Multiple LEDs for easy troubleshooting

REMOTE LED:

• Left LED Off when no Internet connection established

• Left LED On when a connection to the Internet is established

• Right LED blinking when data is being uploaded

• Right LED solid On when data upload complete

METERS LEDs:

• Green LED off and Red LED solid on when no input points have their Display option set to YES. If

no inputs are being displayed then no data will be shown online via MeterData.

• Green LED on when at least one input point has its Display option set to YES.

• Green LED flickers when transmitter wireless data received.

• Red LED blink codes:

o 1 blink: An input point with its Display option set to YES has no transmitter assigned . o 2 blinks: An input point hasn’t been seen for 24 hours (Z ), has a leak alert (L), or a non-

advancing alert (N)

o 3 blinks: A transmitter has a low battery o 4 blinks: A transmitter case is open (T) or the transmitter has been reset (R)

ENET LEDs:

• Green LED solid on when Ethernet has established a connection to the Internet

• Green LED blinking when Ethernet attempting to establish a connection to the Internet

• Red LED blink codes:

o 1 blink: No IP address found. Check to be sure your Ethernet cable is connected to

NoWire and your network has DHCP support to supply an IP address. If you can surf the internet when your laptop is connected to Ethernet cable that you plug into NoWire then your network should be fine.

o 2 blinks: No access to the internet o 5 blinks: Retrying communications to the NoWire Ethernet hardware.

WIFI LEDs:

• Both Green and Red LED remain off. No Wifi SSID name set. To set and use Wifi go to System

Items and select “SI: Wifi Scan/Set”

• Green LED solid on when Wifi has established a connection to the Internet

• Green LED blinking when Wifi attempting to establish a connection to the Internet

NoWire Model 2100 Submeter Solutions, Inc., 888-64METER Page 27

NoWire Model 2100 Installation and Operation Manual

• Red LED blink codes:

o 1 blink: No IP address found. o 2 blinks: No access to the internet o 3 blinks: Wifi SSID not setup. From the System Items menu select the “SI:Wifi Scan/Set”

by pressing change. Press Next to walk through networks found and press Change to select the one you want.

o 4 blinks: Connection to the Wifi Network unsuccessful. Check the selection of your Wifi

Network and the password in the System Items menu. Here is a video on selecting your Wifi Network that may be helpful: https://youtu.be/UXnxWVnZme4

o 5 blinks: Retrying communications to the NoWire Wifi hardware.

MODBUS LEDs:

• Green LED solid on when Modbus is set to Yes in the System Items menu.

• Flicker off when Modbus data is detected on the RS485 Modbus network connected to the D+,

D- and SHLD pins.

11.1.3 Option to Show/Hide meters from display

From the System Items menu Show Inputs option is set to Y by default. If set to N then the input points that have the Display option set to YES will not be displayed on the LCD display. This can be useful if you don’t wish your residents to see the meter readings on the NoWire unit but the meter data is still uploaded and displayed online in MeterData. The Show Inputs option set to Y will display each input point with its Display option set to YES for 5 seconds before moving on to the next one.

11.1.4 Meter non-advancing alert

Each input point with the Nadv Alert (non-advancing alert) option set to Y will be monitored continuously for a change in its meter reading. If the meter reading hasn’t changed for a default of 14 days then the non-advancing alert (N) will be set. This alert is cleared as soon as the Nadv Alert option is set to N or the meter reading changes. The default 14 days may be changed via the “SI:N Alert Days” System Items option.

11.1.5 Barrel type plug in power supply

NoWire 1100 required you to screw the wires of the power supply into the power terminal block. NoWire 2100 has a standard 2.1x5.5mm barrel connector 12VDC, 1A power supply.

11.1.6 Modbus supports both 9600 and 19.2k baud

You may change the “SI:MB 9600 Baud” option in the System Items menu to 9600 baud or 19200 baud when the Modbus option is set to Yes.

11.1.7 Removed Pulse Outputs

NoWire 2100 has no pulse output.

11.1.8 Cell Support via External Gateway

Cellular Connection to the cloud is available for NoWire 2100 by means of a third party external Ethernet to Cellular gateway.
