Wiring your Netbell

Wiring for your Netbell device will be different depending which Netbell product you are using. Please find the section below specific for your Netbell device.
Relay Output Connection
For relay specifications, please see Board Layout Reference.
To wire an external bell or buzzer to your Netbell device:

1. Select a suitable power source that meets the requirements of the Bell/Buzzer.
2. Wire one side of the power source to one side of the bell. The other wire from the power supply is connected to the Netbell’s relay terminal.
3. Finally, connect the other bell wire to the Netbell’s relay terminal.

Note there are variations between different Netbell products.

Netbell-2

There are relay outputs on the Netbell-2. Each relay output has a removeable 2 position connector. These outputs are labeled as “1” and “2” on the top of your Netbell-2’s enclosure.

Caution: Do not mix voltages or voltage types (AC or DC) on circuits connected to the relay outputs. All bells/buzzers connected to output 1 must use the same voltage, and all bells/buzzers connected to output 2 must be the same. The voltages on output 1 can be different from the voltages on output 2. Do not exceed 8 amps at 30VDC or 8 amps at 48VAC per output.

Netbell-8

The Netbell-8 has 8 relay outputs. There are 3 terminals for each relay labelled NO (Normally Open), C (Common), and NC (Normally Closed). To wire a bell or buzzer to a Netbell-8, wire your circuit to C and NO.

Caution: Do not mix voltages or voltage types (AC or DC) on circuits connected to the relay outputs. All bells/buzzers connected to output 1 must use the same voltage, and all bells/buzzers connected to output 2 must be the same. The voltages on output 1 can be different from the voltages on output 2. Do not exceed 3 amps at 48VDC per output.

Netbell-K, Netbell-KL, Netbell-KB, M2 Variants, Netbell-KMB, and Netbell-4K

The Netbell-K series has several products that vary in configuration. Netbell-K, KL, and KB vary by the bell or buzzer built-in to the enclosure and each have one external relay output (2 total). The M2 variants have 2 external relay outputs (3 total). The Netbell-K, KL, KB, or M2 variant are designed to use the included power supply to power the built-in bell or buzzer. The Netbell-4K does not have a built-in bell or buzzer and has 4 total relay outputs.

The Netbell-KMB has no external relay outputs, and instead uses its on-board relays to control the tone of the built-in multitone siren.

To wire an external bell or buzzer follow the above steps connecting the external bell or buzzer to the included bell cable. Then screw the bell cable’s circular connector to the male connector on your Netbell-K’s enclosure.

Note: The relays on all Netbell devices are dry contact meaning your bells or buzzers require their own power supply separate from the Netbell controller’s power supply. These relays do not provide power to the circuit.

IN NO EVENT WILL LINOR TECHNOLOGY BE LIABLE, WHETHER IN CONTRACT, TORT, OR OTHERWISE, FOR ANY INCIDENTAL, SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING, BUT NOT LIMITED TO, DAMAGES FOR ANY LOSS OF USE, LOSS OF TIME, INCONVENIENCE, COMMERCIAL LOSS, OR LOST PROFITS, SAVINGS, OR REVENUES TO THE FULL EXTENT SUCH MAY BE DISCLAIMED BY LAW.

FURTHER NOTICE FOR LIMITATION OF USE
Unless specifically stated, this product is NOT designed to switch line voltage devices. This limitation includes all of FARGO AND KODA products. To control device that operate at line voltages the user MUST install and intermediary device such as a relay. When choosing devices to control, it is best to select low voltage devices such as a 24VAC Bell or Buzzer.

When wiring a line voltage device using intermediary device, you MUST either be a qualified electrician or use the services of a qualified electrician. Additionally, local codes must be followed including but not limited to wire gauge size and suitable housing.

Linortek cannot assume any responsibility for harm to the user or third parties for improperly using our Fargo product. This liability remains with the user. Linortek cannot assume any responsibility for damage to the device for improperly using our SERVER product.

Power Connection

Your Linortek Netbell device is supplied with a suitable power supply. For Netbell-K variants this power supply will also power the built-in bell or buzzer. All external bells and buzzers must have their own power supply.

a) Netbell-2 and Netbell-8 are supplied with a 12VDC power supply. Simply plug in to any 110VAC outlet and plug the barrel end into the 12VDC power connector. See Board Layout Reference. Netbell-2 may also be powered via POE.
b) Netbell-K variants are supplied with either a 12VAC or 24VAC transformer and a power cable that will need to be connected to the transformer. Insert the end of one wire into the left terminal, and the end of the other wire into the right terminal. Finally, tighten the terminals onto the wires. For the 24VAC transformer, disregard the middle (gnd) terminal as it is not used by the Netbell.

Ethernet Connection

Each Netbell device is supplied with an Ethernet cable. The “Connection” LED light on the board will come on if a 100MHz network is available, otherwise it will remain off and the “Activity” LED should start blinking indicating network activity. This will not be visible on a Netbell-K variant unless you open the enclosure. See Board Layout Reference page 15 for more detail.

Digital Input Connection

Netbell-2 and the Netbell-K variants have 2 digital inputs (5-24VDC) built on the board for triggering special notifications/emergency alerts. Netbell-K variants have digital input 1 connected to the enclosure, digital input 2 is accessible inside the enclosure. See Board Reference Layout page 15. A sensor such as a temperature sensor or a push switch can be connected to the digital input. Please note, when connecting a 12VDC-24VDC sensor to the input, an external resistor (provided upon request, 2.2k ohm 0.5watt) must be used.

There are two modes of operation for the digital inputs: ISOLATED and PULL UP.
a) ISOLATED mode allows you to directly drive the Netbell’s opto-isolator with an external voltage though and internal 1K resistor. This voltage may be in the range of 5VDC to 24VDC supplying a minimum of 2mA or a maximum of 30mA to the opto-isolator diode. There is no other internal connection to this voltage so it is an isolated input.
b) PULL UP mode connects a 1K resistor to an internal voltage allowing you to use a simple switch (such as a magnetic door switch) across terminals 1 and 2. When the switch is activated a signal is sent to the input. These modes are selected by the switch on the server (see the board layout for reference) marked ISO and PU for isolated or pullup respectively. On the Netbell put the switch up for pullup and down for isolated.

Netbell-KMB

The Netbell-KMB forgoes the external relay outputs in order to control a multi-tone siren. The siren can play four different tones based on a combination of DIP switches set on the backside of the siren. Each combination changes the four-tone set. When setting a bell schedule, use Bell 1 for the first tone, Bells 1 and 2 for the second tone, Bells 1 and 3 for the third tone, and Bells 1, 2, and 3 the fourth tone. Please refer to the “Creating a Bell Schedule” section, page 9 for more information on the Bell Schedule page. You may also configure tasks in the Tasks page using relays 1; 1,2; 1,3; and 1,2,3. Please refer to the section “Using an External Trigger”, page 11 for more information on the Tasks. Please view the tables in the Netbell-KMB Tones section beginning on page 13 to set the desired tones using the DIP switches on the back of the buzzer. For location of DIP switches and volume control, please see page 18.

Netbell Clock

The Netbell-KC series can output its time to the Linortek Netbell Clock. To drive the digital clock, Navigate to Settings drop-down menu and click Settings. At the bottom of the middle column in the UART Usage field, enter clock. Then click Save. Then plug the clock into the Netbell-KC’s clock output and clock will then obtain the time from the Netbell-K’s software.

Note: The Netbell clock is set by default for GMT-5. If you are in a different time zone, ensure the clock is plugged in to your Netbell-K prior to setting the time and date per the section Setting Time and Date page 7.

Accessing your Netbell Device

Once your Netbell is powered on and connected to the network, it will automatically obtain an IP address via DHCP as long as your router is configured to do so. To connect, enter the IP address into your web browser. This will take you to your Netbell’s landing page. To log in, click the Log In button on the top right of the page. Your browser will prompt you to enter your username and password. By default, these credentials are both set to admin. To find your Netbell’s IP address, see below.

Finding your IP Address with Linortek Discoverer

The Discoverer program will automatically locate your Netbell SERVER. The Discoverer is a Java program, and requires Java Runtime to be installed to use this feature. Java can be found here: http://java.com/en/download/index.jsp.
To download the Discover program, please go to: https://www.linortek.com/downloads/supportprogramming/

Use of Chrome & Firefox browsers is recommended. Please note: If you prefer to use Internet Explorer, Internet Explorer saves Linortek Discoverer as a Zip file by default. In order to use the Discoverer, you will need to select Save as and rename the file as Linortek Discoverer.jar when you download.

When downloading the Discover program, sometimes you will see a popup warning message depending on your browser security settings, asking if you want to keep or discard this file, please click the Keep button as this is a Java program, it won’t harm your computer.

Once Discoverer locates your device, it will display:

Click the device you want to use shown on the Discoverer program to launch the SERVER web pages in your browser. Click the Login button on the homepage. Default username/password is: admin/admin. You may change these as you desire or disable this feature in the settings menu.

Connecting your Netbell Directly to Your PC

You can also plug your Netbell directly to your PC in the case there is no network connection available. If you plug your Netbell into your PC’s Ethernet port it will use the default IP address: 169.254.1.1 unless you have previously configured your Netbell to use a static IP. Enter 169.254.1.1 into your web browser to connect. No internet connection required. Once configured, you can then install your Netbell where desired.

Server Configuration

If you are configuring your Netbell for the first time, or if you are keeping your Netbell disconnected from the internet, see the section below to set your time zone or adjust the Netbell’s built-in time clock. Otherwise Skip ahead to the section Creating a Bell Schedule page 9.

Setting Time and Date

When first configuring your Netbell-NTG you will need to verify the time and date on your home page. Your Netbell-NTG is configured by default to use Eastern Standard Time (GMT-5) and will apply correction for Daylight Savings Time. If your location is not on Eastern Time Zone, please make sure to set your Time Zone first.
CAUTION: Incorrect Time Zone may cause the BELLS not ringing at the right time.

To set your Time Zone, go to Settings – Time/Date page from the drop-down menu, enter your local Time Zone (for example, -5 for Eastern Time Zone, -6 for Central Time Zone, -7 for Mountain Time Zone, -8 for Pacific Time Zone), make sure the Use NTP Update box is checked (when this box is checked, the Netbell will update its time from the NTP server every 30 minutes by default.), then click SAVE button. The system will update its time at its next interval (30 minutes). If you want to get immediate update, you can manually set it to the standard time on the Time box (one hour BEHIND your current time if you use Daylight Savings Time). For example, if your current time is 9:35am, you should put 8:35am on the Time box.

If you wish to use your internal NTP server, please check the How to Use Your Internal NTP Server for Linortek Devices for instructions.
CAUTION: Incorrect settings might cause your devices unable to update the time from the NTP server. The instruction can be downloaded here:

https://www.linortek.com/download/How-to-Use-Your-Internal-NTP-Server-for-Linortek-Devices.pdf
If you intend to keep your Netbell off your network after configuring, you will need to uncheck Use Daylight Savings Time and Use NTP Update. You will then have to manually set the time to account for daylight savings, and adjust the time periodically to account for time creep.

User and Admin Credentials Page
Use this page from the Settings drop down menu. Here you can set up to 3 users for your SERVER system. As a default only User 1 is Active. Here you can:

1. User Name and Password – Each user has their own credentials. As a default these are set to admin/admin, user2/user2 and user3/user3 for Users 1, 2 and 3 respectively. The passwords are never displayed. Note: when you reset the password, it must be less than 13-character.
2. Active – Must be checked for this user to sign on, you cannot deactivate User 1.
3. Admin – Only admin can save data in most pages. This protects your SERVER from being changed by an unauthorised person.
4. Timeout – Not enabled at this time.

Creating a Bell Schedule

Once your time and other settings are configured, you can then create your bell schedule. This can be done using the Netbell’s Bell Schedule.

Creating a Bell Schedule from the Bells Page

Each Netbell can set up to 500 bell event schedules. To add an event schedule, navigate to the Services dropdown menu, then select Bells. You will see the following page:

You may use this page to enter up to 500 events. An event can be created in 9 simple steps.

1. Enter an event name up to 15 characters long (Use letters and numbers only)
2. Use the 3 fields labeled Time to enter the time in HH:MM:SS (Note: the first field to select the hour uses a 24hr format. For 12 AM select 00, for 1 PM select 13)
3. (Optional) Enter a date. This will trigger the event only on this specific date
4. Enter a duration. Open the dropdown menu on the second box and choose either mS, Sec, or Min for milliseconds, seconds, or minutes respectively. In the first box then enter a value determining how many of the chosen unit of measurement
5. Click the Add button. You will see this event listed above. Subsequent events will be listed in chronological order
6. Once an event is added, you may adjust which relay output is triggered by selecting pips 1 – 8 under the Bell column. By default, 1 and 2 are automatically selected. Note which numbers you are using as you will need to assign a sound to each one. For numbers 5 – 8 see the section Activating Extended Relay Range on page 19
7. You may choose which days of the week will use this event under the Day column. Days are listed Sunday – Saturday (Note: if a specific date is chosen it will override the Day column)
8. Check the Use box to enable this schedule. If you only want it to trigger one time, check the Once box
9. Finally, click Save

Deleting Items
You can delete an item from your schedule by clicking the DEL button to the right of the list. To clear the entire schedule, enter #!reset@memory! Into the Name field and click Add.

Uploading a Premade Schedule

You may upload a Premade schedule by entering #upload into the Name field and click Add. This will take you to a new page. Click Choose File to browse your computer for the schedule in either .txt or .csv format. Once selected, click Upload. This will return you to the previous screen with your new schedule listed.

You can create a schedule using a Plain Text editor such as Notepad. Your first line should be #Start – each subsequent line will be a separate entry with 13 items, each separated by a comma. Save this file as Plain Text (.txt).

Below is a sample prewritten bell schedule.

Saving your Bell Schedule

To save the bell schedule on your Netbell, click on the Download button in the bottom-right. This will open a new tab in your browser and display the schedule as plain text. Copy and paste this text into a plain text editor such as Notepad and save.

Creating a Bell Schedule Using the Bell Scheduler Desktop App

There is a free desktop app to create a bell schedule available at: https://www.linortek.com/downloads/support-programming/
Documentation is available at: https://www.linortek.com/downloads/documentations/

Using an External Trigger

You may also program your Netbell to ring a bell upon input from an external trigger such as a pushbutton or door contact switch.
Note: unless your trigger device supplies its own power, ensure your input switch is set to Pull UP (See Wiring your Netbell page 5 and Board Layout Reference page 15)

Setting the Digital Input

Note: The following guide will assume you are using Digital input 1 and using a bell connected to relay 1.

Navigate to the Services dropdown menu and select Inputs or IN/OUT. The Digital inputs will be listed as DIN 1 and DIN 2. Click on the blue pencil icon under DIN 1 and enter the following settings.

1. Enter a name in the Name field (if desired)
2. Enter a label in the Label field (if desired)
3. Check the Use box
4. Set Type to State
5. Set Command L/Z/N/I to i
6. Click SAVE

Setting Task for Digital Input
Now that your external trigger is wired to your Netbell and your digital input is configured, now you will need to set up two tasks.

1. Navigate to the Tasks page
2. Click the Edit icon on the first available task
3. Name the task if desired
4. Check the Use box
5. Set Device A to Digital
6. Set Data A to 1S=1 (1 represents the number of the digital input, S signifies to your device to refer to input state, the last 1 signifies the state is on)
7. Set Device C to Relay
8. Set Data C to 1
9. Set Action to ON
10. Click Save
11. Next, click the Edit icon on a second availavle task.
12. Copy the same information from the first task, change Data A to 1S=0 and change Action to OFF

If you are using a trigger such as a door contact switch, set Data A in the example above to 1S=0 in the first task, and 1S=1 in the second task to ring the bell when the contact is broken. You may set multiple relays in Data C by separating the numbers with a comma (ex: 1,2,3).

Additionally, you may wish to turn off the relay timer to keep the bell ringing as long as the button is pressed or door contact is broken by navigating to the Services drop down menu and selecting Relays or IN/OUT. In the Relay Control section, click the Edit icon and erase the value in Pulse Width, and set Pulse Width Multiplier to None. Note that your scheduled bells will override this setting.
