ES Net High Speed Networks

High-speed, high-capacity fire alarm and life safety network

Supporting up to 687 nodes, ES Net is incredibly scalable and highly resilient with the capacity to handle even the largest multi-building campus environments.

  • One network carries data, audio, firefighter telephone, and supplemental system data
  • ES Net features automatic notification appliance synchronization and no special programming, wiring, or adapter modules are required
  • ES Net can support virtually any size facility, from a single building to a large campus with hundreds of nodes

Perfect for Large Multi-Building Campuses

The Simplex ES Net IP-based fire and life safety network optimizes system design and installation flexibility while increasing network capacity, speed, and performance. ES Net supports ring, star, bus, and bridged ring network topologies. As you can combine multiple topologies, you can create fault-tolerant networks while mixing and matching media (Ethernet, DSL, and fiber) between nodes to optimize cost and span long distances. High speed and advanced design allow ES Net to carry fire alarm system data and audio traffic with plenty of bandwidth to spare. You can use that extra capacity to transport data from your other systems, such as access control security, and building automation, reducing network wiring, installation and equipment costs. ES Net is supervised and fault tolerant, with a peer-to-peer design that allows it to continue operating even if multiple nodes fail. ES Net also keeps fire alarm data separate from other traffic, ensuring it has top priority and always gets through.
Perfect for Large Multi-Building Campuses


  • High speed, high capacity:The TCP/IP-based, 100 Mbps network supports up to seven network loops and 687 nodes.
  • Faster, easier system upgrades:A technician connected to a single ES Net node can upload software updates to all 99 nodes on a network loop in minutes.
  • Easy migration for existing Simplex installations: ES Net and Simplex 4120 networks can be integrated using a TrueSite Workstation, allowing both types of networks to be monitored on the same console.
  • Multiple topology support:A wide range of supported configurations means greater design and installation flexibility. ES Net also allows you to mix and match media.
  • Advanced diagnostics:Powerful network diagnostic tools and reports help reduce system troubleshooting time and technician effort.
  • Better fault tolerance and resiliency:ES Net is designed to be reliable and resilient, automatically reconfiguring communication when necessary.


Speed And Versatility

ES Net is a 100Mbps network that supports multiple topologies, media and supplemental network traffic.


ES Net detects degraded and non-replicated paths between nodes and automatically reconfigures communication to help deliver uninterrupted network communications and operation.

Coordinated Emergency Response

The Simplex TrueSite Workstation manages an entire fire and life safety network from a single location. TrueSite Workstation alerts users to emergencies and promotes a faster, more accurate response.

Fast And Easy Upgrades

A technician can quickly update every node on a network from a single point, eliminating the need to physically access each node and dramatically increasing system availability and technician productivity.
