1. Introducció i finalview
The Algo 8128G2 is a second-generation Power over Ethernet (PoE) SIP compliant IP strobe light designed for Voice over IP (VoIP) notification and SIP alerting. This device supports SIP Ring, SIP Subscribe Notify, Dry Contact Closure, and Multicast, operating independently of an IP telephone. The 8128G2 features an upgraded hardware platform (G2) compared to its predecessor, offering enhanced multicast options, dedicated "Emergency Alert" extensions, and more. It supports advanced protocols such as TLS, SRTP, SIP TCP, DNS SRV, and CDP/LLDP, and can integrate with InformaCast (requires separate license). Equipped with multiple high-intensity, long-life LEDs, the 8128G2 provides visual alerts for telephone events, emergency situations, and safety/security notifications, meeting standards like OSHA and ADA. It offers 20 configurable flash patterns and adjustable intensities to suit various environments, including noisy or noise-sensitive areas. Optional colored lenses (amber, blue, red) are available separately. The 8128G2 is suitable for mass notification applications and can be combined with other Algo IP endpoints for comprehensive audible and visual alerting solutions in enterprise and campus settings. It requires standard 802.3af Power over Ethernet; a PoE Injector is necessary if PoE is not available. Direct power connection is not supported. Basic understanding of computer networking and VoIP is recommended for configuration.

4.2 Connexió de xarxa (PoE)
The 8128G2 is powered exclusively by Power over Ethernet (PoE) compliant with 802.3af. Connect a standard Ethernet cable from your PoE-enabled network switch or PoE injector to the "NETWORK" port on the back of the 8128G2. The device will power on automatically once connected to a valid PoE source.
- Ensure your network switch provides 802.3af PoE.
- Do not attempt to connect external power supplies to the device.
4.3 Configuració inicial (Web Interfície d'usuari)
The Algo 8128G2 is configured via its built-in web interfície d'usuari (Web-UI). You will need to obtain the IP address of the device to access its configuration page. This can typically be found through your network's DHCP server logs or by using network scanning tools.
- Connect the 8128G2 to your PoE network.
- Obtain the IP address assigned to the device.
- Obre a web navegador en un ordinador connectat a la mateixa xarxa.
- Enter the IP address of the 8128G2 into the browser's address bar and press Enter.
- Log in using the default credentials (refer to the device's documentation or Algo's weblloc web per al nom d'usuari/contrasenya predeterminats).
- Once logged in, you can configure SIP settings, flash patterns, multicast options, and other features.
5. Instruccions de funcionament
The Algo 8128G2 operates by receiving SIP, multicast, or dry contact signals to trigger visual alerts. Configuration of these triggers and the resulting strobe behavior is performed through the web interfície.
5.1 Strobe Pattern Configuration
The 8128G2 offers 20 configurable flash patterns with adjustable intensities (High/Low). These patterns can be assigned to different alert types (e.g., SIP ringing, emergency alerts).

Figure 5.1: Screenshot of the "Strobe" tab within the 8128G2 Control Panel, showing options for defining and testing flash patterns and brightness.
To configure strobe patterns:
- Navigate to the "Strobe" tab in the web interfície.
- Select a pattern from the dropdown menu and choose its brightness (High/Low).
- Use the "Test" button to preview the selected pattern.
- Deseu els vostres canvis.
5.2 Advanced SIP Settings
The "Advanced SIP Settings" section allows for detailed configuration of SIP transportation, security (TLS, SRTP), NAT traversal, and server redundancy. This is crucial for integrating the 8128G2 into complex VoIP environments.

5.3 Alertes d'emergència
The 8128G2 supports up to 10 dedicated extensions for triggering emergency alerts. Each alert can be configured with a specific strobe pattern, multicast zone, and authentication details. This allows for rapid visual notification during critical events.

Figure 5.3: Screenshot of the "Emergency Alerts" tab, showing configuration fields for up to 10 distinct emergency alert extensions, including strobe pattern and multicast zone.
5.4 Configuració d'entrada/sortida
The device includes input and output relay terminals. The input can be configured to trigger a specific flash pattern based on a dry contact closure (e.g., from a panic button or sensor). The output relay can be enabled to control an external device.

Figure 5.4: Screenshot of the "Input/Output" tab, detailing settings for relay input mode, action upon input trigger, wiring fault supervision, and output relay control.
5.5 More Page Extensions (Multicast Paging)
The "More Page Extensions" section allows for the configuration of dedicated extensions for paging zones. This provides an alternative to DTMF selectable zones, enabling direct paging to specific areas without DTMF input. This feature is useful for integrating the strobe into a comprehensive multicast paging system.
