Packing List and Quick Setup Guide

Important Notes:
• All devices must be on the same local network
• Follow steps in order for a successful configuration
• When testing in the same room/area, to prevent audio feedback:
 Keep the phone and speaker far apart and facing away from each other
 OR reduce speaker volume to below 50 to prevent audio feedback

Preparation for Installation
To achieve the best audio quality for your IP paging system, we recommend building a dedicated VLAN for this system with network equipment compatible with multicast protocol. Netbell IP paging devices support PoE/PoE+ (except Netbell-AU-711), and a properly configured network infrastructure will ensure a smooth installation.
Important Requirements
• The devices and the PC running the NACT desktop app must be on the same LAN
• Network and Switch Requirements:
 Power over Ethernet (PoE/PoE+) Switch Ports
 Minimum CAT5 cable with maximum of 100 meters from the device to switch
 Network switch capacity to handle power loads for all devices
 Router: Must support IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast)
 Switch: Must support IGMP snooping
Important Pre-Installation Planning
We strongly recommend completing all device configuration before physical installation in your facility. This systematic approach will significantly reduce installation time, minimize errors, and simplify troubleshooting. Please follow these pre-installation best practices:
• Create a Network Plan: Document your IP addressing scheme, ensuring all devices have compatible network settings (subnet mask, gateway, etc.)
• Assign Static IP Addresses: Configure and document static IP addresses for all devices to prevent communication issues that can occur with changing DHCP addresses
• Create and Configure Groups: Set up all your speaker groups and ensure proper device assignments before physical installation
• Maintain Documentation: Create a detailed spreadsheet recording:
 Device numbers and names
 Assigned IP addresses
 Physical installation locations
 Group assignments
 Special settings or configurations
• Verify Configuration: Test all devices while they’re easily accessible to confirm proper operation before mounting in hard-to-reach locations
Following these recommendations will create a more manageable deployment process, especially for multi-device installations across larger facilities.

• Click Control and Status tab
• Configure the following:
 Key input mode: Hold

d. Setup the Communication and Priority
Understanding Broadcast Priority
When operating multiple Netbell-AU-711 devices within a single system, you must establish a priority hierarchy to manage competing broadcast signals. This hierarchy determines which device’s audio will play when multiple broadcast commands are sent simultaneously.
Setting Up Speaker Communication
To enable broadcasting to your speakers, you need to configure the communication pathway between your Netbell-AU-711 devices and speakers (zones). This ensures proper signal routing and audio delivery throughout your facility.
Configuration steps:
• Click the Control1 settings under Control and Status
• Set Key Input Mode to Encode
• Select one of these options:
 Unicast: for direct speaker communication (enter its IP address below)
 Multicast: to cast to a group of speakers (enter Group Number below)
 Broadcast: to cast to all available devices on this LAN
• Leave Target field empty
• Priority: Choose based on your needs:
 Set to 1 if you want this device to override other broadcasts
 Set to 0 if you want other broadcasts to override this device
Important Note: If you want Netbell-NTG to have lead priority (so that alarms will go through even if there is something else broadcasting to the same group of speakers), assign it priority 1.
Click Save to apply all configurations and exit the configuration menu.

4. Netbell-NTG Configuration
a. Link the Netbell-NTG as a Remote Device
