アプリケーションの概要
Early warning fire alarm systems are required to detect fires, alert residents and send alarms to the fire department and emergency response agencies. Industrial Ethernet devices are needed to ensure the fire alarm systems are always active.

Volktekのメリット
| Feature | Benefit | ||
| Reliability | Redundant Power and Alarm Relay | Operate one even one goes down |
1) Built-in surge protection, dual power sources, and battery backup 2) ensure stable device operations for 24/7 network reliability. |
| Availability | Multi-Rate Fiber Port | Auto Uplink and Downlink |
1) Set the uplink/downlink speeds accordingly 2) Optimize their performance in the data transmission. |
| Performance |
LLDP Filter | Blocks the LLDP packets exchange at unmanaged devices without disturbing managed ones. | During the network discovery process device flapping issue can be occurred when the peripheral devices are connected to an unmanaged switch in the network. The Link Layer Discovery Protocol (LLDP) Filter blocks the LLDP packets exchange at unmanaged devices without disturbing managed groups to avoid the device flapping issue. |
| VLAN Passthru | Connect Remote Devices | Helps to communicate with different devices by receiving and transmitting VLAN packets without losing or configuring them. | |
| Quality of Service (QoS) | Define the Critical Networks |
1) Specific networks can be prioritized 2) Optimize the network performance and bandwidth utilization |
|
| Security | Access Control List (ACL) | Additional Security with Controlled Network Traffic | Create filter rules for forwarding specific packets or denying network access. Network administrators use to filter traffic and provide an extra layer of network security. |
| Management | Modbus and PROFINET | Support Industrial Protocols | PROFINET is an industrial standard for data communication over industrial ethernet, designed for low-latency data collection and controlling equipment. Modbus is a serial communication protocol typically used to transmit signals from instrumentation and control devices back to a main controller or data management system. |
| Simple Network Management Protocol (SNMP) + TRAP | Monitor Your Network From a Single Location | SNMP allows large networks with thousands of nodes to be monitored from a management host. The data is used for collecting and configuring information for devices such as servers, printers, hubs, switches, and routers. Volktek's managed switches provide management of SNMP traps or alert messages sent from a remote SNMP-enabled device to a central SNMP server. Effective trap management offers agentless monitoring, increase server, services, and application availability, and fast detection of network outages and protocol failures. | |
