Simplex ES Net IP-Based Life Safety Network

Simplex ES Net IP-based fire and life safety network from Johnson Controls optimizes system design and installation flexibility while increasing network capacity, speed and performance. Supporting up to 687 nodes, ES Net is incredibly scalable, highly resilient and has the capacity to handle even the largest multi-building campus environments. 

ES Net supports multiple network topologies (ring, star, bus and bridged rings) for enhanced design and installation flexibility, improved fault tolerance and the potential to reduce the conduit and wiring. A redundant system with battery backup, ES Net can also support supplemental network traffic without any interference to fire alarm and life safety traffic. Devices such as security cameras, access control and building automation systems can now be seamlessly supported across the UL Listed, supervised network. 

ES Net harnesses the power of IP technology with data rates up to 100MB per second and a range of network connection choices including Ethernet, DSL and fiber, giving building owners a platform for future growth and integration. Centralized system management and increased bandwidth also allow for quicker upgrades to reduce downtime and operational expenses.

ES Net provides greater flexibility during network expansion and allows up to 82,000 feet (25 Km) between nodes. The network’s increased memory capacity, advanced diagnostics and broad bandwidth helps maximize uptime, deliver consistent performance and support future expansion and enhancements.


High speed, high capacity

TCP/ IP based, 100 Mbps network which supports up to seven network loops and 687 nodes. 

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, helping optimizing cost and performance.  

Examples of ES Net supported architecture: 


Faster, easier system upgrades from a single point

A technician connected to a single ES Net node can upload software updates to all 99 nodes on a network loop in just a few minutes. This eliminates the need to physically access each node and dramatically increases both system availability and technician productivity.

Advanced diagnostics

Advanced network diagnostic tools and reports help reduce system troubleshooting time and technician effort. 

Easy migration for existing Simplex installations

ES Net and Simplex 4120 networks may be integrated using a TrueSite Workstation, allowing both networks to be installed and monitored within a facility. In some cases ES Net can utilize the facility's existing 4120 network infrastructure, making it easy and cost effective to upgrade to ES Net.  

Better Fault Tolerance and Resiliency

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