Here’s a technical write-up based on a simulated investigation of the Simplex ES Panel Programmer (associated with Simplex 4010, 4100ES, and 4100U fire alarm control panels).
| Feature | Detail | |---------|--------| | Model | 420-1040 | | Display | 4.3” color touchscreen | | Connection | USB-A (to panel), micro-USB (charging) | | Battery | Rechargeable Li-ion (~8 hr active use) | | Supported Panels | 4100ES, 4010ES (firmware v2.0+) |
The Simplex ES Panel Programmer is a proprietary software tool used to configure, program, and troubleshoot Simplex fire alarm systems, specifically the 4100ES and 4010ES series. Unlike older Simplex tools (e.g., HyperTerminal-based or legacy DOS programmers), the ES Programmer operates within a Windows environment and communicates via serial (RS-232) or USB-to-serial adapters. simplex es panel programmer
Key Functions:
Using a serial port monitor (e.g., Free Serial Port Monitor or ComSpy), the following was observed during a "Upload from Panel" operation: Here’s a technical write-up based on a simulated
Initial handshake:
PC sends 0x02 0x45 0x53 0x03 (ASCII STX, "ES", ETX).
Panel replies with 0x06 (ACK) plus firmware version string.
Packet structure (observed):
[STX] [CMD] [LEN] [DATA...] [CRC16] [ETX] Common commands captured:
Common commands captured:
0x10 – Request point database (returns device type, address, custom label)0x21 – Write mapping equation (for logic zones)0x33 – Set device sensitivity (for detectors)0x7F – Panel time/date syncThe protocol is not encrypted but uses proprietary address mapping. Attempts to inject commands without valid session authentication caused panel reboot (watchdog reset).
