Elias keyed in the command to edit the device. He selected the NAC (Notification Appliance Circuit) output. This was where the magic happened. In the old days, you’d need to physically cut wires and jump terminals. Now, it was software logic.
Before writing a single line of logic, ensure you have the correct hardware to interface with the panel: simplex es panel programmer
The Simplex ES Panel Programmer is the dedicated software application used to create, edit, and manage configurations for the ES Series of fire alarm control panels. Unlike many other systems, ES Series panels cannot be programmed directly from their front interfaces. Instead, the programmer is a Windows-based application that provides a graphical interface for building a complete site configuration, known as a "job," and downloading it to the panel via an Ethernet connection. This configuration defines every aspect of the system's operation, from which devices trigger which alarms to how the panel communicates across a network.

Always backup the existing panel program ( .sdb file) before making any modifications. Save new iterations with a clear naming convention that includes the date, technician initials, and a brief change description (e.g., BuildingA_4100ES_V2_2026_05_19_JD.sdb ).
The Custom Control tab includes wizards that simplify the creation of complex life safety strategies.
Programming a fire alarm panel carries immense liability. Following industry best practices ensures life safety compliance and system stability:
