Honeywell gas detector 04230-A-1001 hand controller

**Product Overview**  

The Honeywell Model 04230-A-1001 is a dedicated hand controller (or programmer) designed for the configuration, calibration, and maintenance of specific Honeywell fixed gas detection systems. It serves as a vital portable interface for field technicians, enabling efficient setup and troubleshooting of gas detectors without requiring complex disassembly or direct panel adjustments.

**Key Technical Specifications**  

*   **Compatibility:** Designed primarily for use with Honeywell (formerly General Monitors) fixed gas detectors, including the S5000 and S5100 series, and other compatible control monitors. Exact compatibility should be verified with the system manual.

*   **Interface:** Features a built-in graphical LCD display and a keypad for menu navigation and data entry.

*   **Connection:** Typically connects to the target gas detector or control system via a proprietary cable or direct plug-in interface (specific connector type varies by detector model).

*   **Power Supply:** Powered directly through the connection from the host detector or control system; requires no internal batteries.

*   **Functionality:**  

    *   Performs sensor calibration (zero and span adjustments).  

    *   Configures alarm setpoints (low, high, TWA, STEL).  

    *   Displays real-time gas readings and system status.  

    *   Accesses and clears fault logs and event histories.  

    *   Sets output configurations and communication parameters.

*   **Environmental Rating:** Generally intended for use in indoor or sheltered industrial environments. Specific ingress protection (IP) ratings should be confirmed via the product datasheet.

*   **Physical Characteristics:** Constructed with a durable, handheld housing. Exact dimensions and weight are model-specific.
