Netbell Warehouse Factory Break Time Paging System

When first configuring your Netbell, you will need to verify the time and date on your home page. Your Netbell is configured by default to use Eastern Standard Time (GMT-5) and will automatically adjust for Daylight Saving Time. If your location is not in the Eastern Time zone, please make sure to set your Time Zone first. Using an incorrect time zone will cause the bells to ring at the wrong time.

To set your Time Zone:

• Go to Settings > Time/Date
• 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)

Note: If an ethernet connection is not supplied during normal operation, the Netbell will be unable to receive NTP updates. This can lead to a misalignment of you schedule over time. To fix this provide an ethernet connection and either manually correct the time in the time textbox or set NTP Interval text box to 1, receive an NTP update, and set it back to 30 afterwards.

Upon logging into your Netbell-NTG for the first time you will need to activate the audio system.

1. Navigate to the SETTINGS dropdown menu, then click SETTINGS.
2. Check the box Extend Relay Range
3. Enter audio in the UART Usage field (not case sensitive).
4. Check the box Use Audio File System.

Click SAVE, the device should start playing through the files on the SD card now.

In order to multicast audio to your IP based speakers, you will need to link the AU-711 to the NTG as a remote device.

To do so go to Configuration -> Remote Device Config

• Name the device
• Enter the IP address for your broadcast terminal (AU-711)
• Click Save

Take Note of the Remote Device No., as it will be used in futured device configuration

You can assign the audio tone to any relays (1-8), so you can schedule that tone from the scheduling page (Services -> Bells page).

Tip: when you go to Services -> Relays page, only 4 relays are visible. To enable 8 relays, go to Settings -> Settings page, check the Extend Relay Range box, then click SAVE. To view all 8 relays, go to Services->Relays page, change the relays4 to relays8 in the URL. For example, the URL on your Services->Relays page might look like this: http://172.16.10.105/p/relays4.htm, you can change it to: http://172.16.10.105/p/relays8.htm to see 8 relays.

The device comes installed with 40 default sounds from the factory, these sounds can be heard at our website: Netbell-NTG Standard Sound List – Linortek Resources.  If you prefer to use custom sounds or your pre-recorded messages, you can do so by adding those sound files to the SD card up to 10 hours as long as you convert the messages to OGG format (The Netbell-NTG uses .ogg file format for the playback of audio). If your custom sounds or messages are not in this format you will need to convert the file to an .ogg file using a free program called Audacity.  For instructions on how to create customer sounds for the Netbell-NTG, please refer to Creating Custom Sounds. We will use the tone named “BELLT001” and assign it to Relay 1 (bell 1) as an example here.

1. Navigate to the Tasks page on your Netbell-NTG
2. Click the Edit icon at the end of the first available line
3. Enter a name (if desired) in the Schedule Name field
4. Check the Use box
5. Set Device A to RELAY
6. Set Data A to 01+ (This refers to the Bell 1 on the bell schedule page for bell 2, 3, … use 02+, 03+, …)
7. Set Device C to SEND UART
8. Set Data C to PBELLT001OGG (This must be an 8-character name preceded by P and followed by OGG. This must be capitalized)
9. Set Action to ON

Click SAVE

To direct audio to specific speaker groups, each relay must be associated with a designated speaker group.

For example, if the tone “BELLT001” is assigned to Relay 1, and Relay 1 is linked to Speaker Group 7, then Speaker Group 7 will play the “BELLT001” tone whenever Relay 1 is activated.

To Link the Relay to a speaker group:

• Go to Services -> Relays
• Click the edit button for the desired relay (Bell)
• For pulse width enter at least the duration of the audio file (minimum value 5 Secs) using:
  • Pulse Width: Numerical value of time
  • Pulse Width Multiplier: Unit of time to be tracked
• Relay type: Normal and Remote
• Location ID: Remote Device No. for your broadcast terminal
• Relay at Location: Group # of speakers

Once the audio system is enabled and you have assigned a tone/message to a relay, you can then program your Netbell-NTG for audio playback. This can be done using the Netbell-NTG’s built-in bell scheduler, or by using an external signal as a trigger.

Creating a Bell Schedule from the Bells Page:
Each Netbell-NTG 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.  Duration: Enter any number in the Duration box and select a duration multiplier (mS, Sec, Min), DO NOT SKIP. The max duration the Netbell-NTG can play depends on the length of the audio file. For example, if the audio file is 10 seconds, it will continuously play for 10 seconds no matter what duration you set here.
4. (Optional) Enter a date. This will trigger the event only on this specific date
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.
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

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

Saving your Bell Schedule
To save the bell schedule on your Netbell-NTG, 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.

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.

Creating a Bell Schedule Using the Bell Scheduler Desktop App (optional)
There is a free desktop app to create a bell schedule available at: Support Programming – Linortek Resources
Documentation is available at: Bell Scheduler Documentation

You may also program your Netbell-NTG to play a tone upon input from an external trigger such as a push button or door contact switch.
Note: unless your trigger device supplies its own power, ensure your input switch is set to Pull UP (PU) (See Wiring the Netbell-NTG and Board Layout Reference)

Activating the Digital Input
