Master-Slave Setting Instructions for Emergency Notification Using

Netbell-NTG and Koda100 Controllers

All of the devices we manufacture include a remote function that can deliver a signal from one controller to control

other device(s) in multiple locations. With the capability of playing live and pre-recorded messages on the Netbell-NTG

industrial PA system, you can use it with the Koda 100 Ethernet I/O controllers to build a network emergency

notification system. The feature is useful for schools or factories that have a need for audible signals in separate areas or

multiple buildings where running additional wiring is too expensive or not practical.

In this instruction, we use a Netbell-NTG PA system and two remote switches to activate the emergency sound. Each

remote switch is connected to a digital input of the Koda 100.

Environments:

• The system will be installed on the same building, all network switches are on the same subnet.

• Running wires across the buildings are not practical.

Functions required for the system:

• Any person on the plant floor/office can press an alarm switch if an emergency is spotted and the speakers in

the facility will play the pre-recorded emergency sound.

• After the pre-recorded message is played, it will turn off automatically unless you push one of the switches to

trigger the sound again.

Devices to use

• One Netbell-NTG PA system: One Netbell-NTG tone generator controller, multiple horn speakers, one mixer-

amplifier.

• Two Koda 100 Ethernet I/O controllers: Each push switch will need a Koda 100 controller to send the signals to

the Netbell-NTG controller to activate

the sound.

• Two Push Switches.

Devices installation map

As shown on the map. Here are the devices

installed in the building, to better explain the

system setup process and software

configuration, the Netbell-NTG is used as the

Slave controller and named SLAVE in the

software configuration. The Koda 100 devices

are used as Master controller, named as

Master 1 and Master 2.

Wiring

1. Wire Netbell-NTG PA System

For details on how to wire the Netbell-NTG PA system, please refer to the Wiring the Netbell-NTG section on the

Netbell-NTG User Manual, below is the wiring diagram from the manual for your reference:

2. Wire the push switch to Koda 100 digital input

There are two digital inputs on the Koda 100 controller, they are marked as IN1 (input 1), IN2 (input 2) on the

enclosure, you can connect the push switch to either of the input to trigger the alarm on/off. There are two modes

of operation for the digital inputs: ISOLATED (ISO) and PULL UP (PU), it’s set to ISO mode by default. To use the push

switch with the digital input, you first need to put the digital input switch to PU mode.

To put the digital input switch to PU mode, open the enclosure of the Koda 100, find the switches marked as IN1 IN2

and put it into the DOWN position for PU mode depending on which input you connect the push button.

Software Configuration

Once the controllers are 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. For instructions on how to find the IP address for each device, please refer

to Finding the IP Address to Access the Software section on the Netbell-NTG User Manual.

1. Network Configuration

Each device uses SERVER as the default name, when you have multiple devices on the same network, you can change

the device name for easy management. To change the name, go to Configure – Network Config page, it’s the same page

for network configuration below.

To use the Master-Slave feature, we encourage you NOT to use DHCP on your controllers, use a static IP or a specific IP

address if your network allows. So that in the event of power outage, you will not need to reset IP addresses. To use

static IP and change the name for your device, go to Configure - Network Config page, this page allows the configuration

of the SERVER's network settings.CAUTION: Incorrect settings may cause the board to lose network connectivity. If the

devices are on different network, in order to access a device remotely you must PORT the device. This tells your router

that information coming in should be sent to a specific device on your network.

• MAC Address – This is a unique MAC address that is assigned to this product at time of assembly. It

cannot be altered.

• Host Name – This is a Netbios name at which this unit may be addressed in some networks. It may also

appear in your router's lease directory. It makes a useful place to name your SERVER and appears on the

Home page and on the Discoverer.

• Port Number – This becomes part of the IP address and is necessary for Internet access. If this is not set,

the SERVER defaults to a port number of 80.

• Enable DHCP: DHCP is enabled by default. When the device is first installed on the network, it will

automatically obtain and IP address if your router is setup for this way. To use a static IP address, uncheck

this box.

• IP Address – Typically you only change the last group of numbers. If you change this IP address, make sure

to reserve this IP on your router and no other devices are using this IP address or you may not be able to

reach this SERVER. If this happens you may need to Restore Defaults using the push button method.

• Gateway – Typically a router on your TCP/IP network that serves as an access point to your ISP.

• Subnet Mask – A 32-bit number that masks an IP address, and divides the IP address into network address

and host address. Just leave it at 255.255.255.0

• Primary DNS – A primary DNS.

• Secondary DNS – A secondary DNS.

2. Configure the Slave Controller (Netbell-NTG)

2.1 Assign a tone to a relay

You can use any custom messages up to 10 hours on the Netbell-NTG as long as you convert the messages to OGG

format. We recommend to use a sound file that is not less than 15 seconds for better results.

For instructions on how to create customer sounds for the Netbell-NTG, please refer to Creating Custom Sounds section

of the Netbell-NTG User Manual. We will use a custom sound “WARNINGE” as an example in this instruction.

2.1.1 Enable Audio File System

• Navigate to the SETTINGS dropdown menu, then click SETTINGS.

• Enter Audio in the UART Usage field (not case sensitive).

• Check the box Use Audio File System.

• Click SAVE, the audio system is now enabled.

2.1.2 Assigning Audio tone to Relay

As we use a relay to trigger a tone on the Netbell-NTG controller, the relay is just a tool for this purpose and not

functioning as a physical switch in this case. You can assign the audio tone to any relays (1-8), when you link the Master

controller to the Slave, you just need to link to the same relay you have assigned a tone to at this step.

• Navigate to the Tasks page of Slave-A

• Click the Edit icon at the end of the first available line

• Enter a name (if desired) in the Schedule Name field

• Check the Use box

• Set Device A to RELAY

• Set Data A to 01+ (This refers to the Bell 1/Relay 1 on the bell schedule page for bell 2, 3, … use 02+, 03+,

…)

• Set Device C to SEND UART

• Set Data C to PWARNINGEOGG (This must be an 8-character name preceded by P and followed by OGG.

This must be capitalized)

• Set Action to ON

• Click SAVE

3. Configure the Master Controller (Koda 100)

3.1 Link the Slave controller to Master-1 controller through its IP address

• Go to Configure menu, then select Remote Device Config from the drop-down menu.

• On the Remote Device page, enter the Slave device information, including Device Name, IP Address, Login User

Name and Password.

• Click Save Config button after finish.

The Remote Devices page for the Master 1 controller will look like this:

3.2 Activate the digital input

To set the push switch to trigger the relay. Go to Services – In/Out page, click Input 1 (IN1) edit icon if you connect the

switch to input 1, you will be at Set Digital Input page.

• Name: You can set a 15-character name for this input. This name goes in the bar at the top of the display.

• USE: Sets this input to active. When this box is checked, it will turn the input number indicator to green.

• Type: Select State, this is for knowing if an input is on or off.

• Display: This selection lets you change the display type used.

• Relay L/T: Enter 1T, which means this input is to trigger relay 1.

• Click SAVE button.

3.3 Use Master relay 1 to trigger Slave relay 1

Go to Service – In/Out page, select Relay 1, click the Edit icon, you will be at the Set Relay page.

• Name: Give this relay a name if you like.

• Pulse Width: The relay on the Master is used to activate the sound on the Slave controller, you can leave it by

default.

• Pulse Width Multiplier: Leave it as default.

• Relay Type: Select Normal and Remote.

• Location ID: Enter the remote devices ID which we set on Remote Device Setup page; the first column No. is the

device ID (SLAVE is on line 1, so the device ID is 1 in our example).

• Relay at Location: From 1-8, depending on which relay you assigned the tone to on the slave controller (Since

we assigned a tone to relay 1 in our Slave device setup, so we put 1 here).

• Click the Save button.

The Master relay 1 has been linked to the Slave relay 1.

Now, we have connected the switch 1 to activate the emergency sound on the Slave controller, when someone pushes

the switch, it will ring the emergency sound.

Doing the same for Master 2. If you have more remote switches, connect the Slave controller to each Master

controller exactly the same way like we did for the Master 1 above.
