    How Diagnose Fire Dirty on Non Smoke Head MUX Device

    Part numbers FPD-7024, D7024, DS9400, DS9400I, DS9400M, D7039, FPE-7039, DS9431, D7044, D7044M, D7052, MX361, MX361M, MX363

    Issue

    Keypad is showing FIRE DRTY PT ### but that point number is a single input module.

    Solution

    The most likely cause of a single input or dual input point showing dirty on the keypad is if it was incorrectly programmed as a mux smoke.  To change this, follow these directions:

    1. Go into program mode at the panel
    2. Choose 9 for Program Mux
    3. Choose 1 for Mux Edit
    4. If the module is a single input module, choose 2 for Single Input; or if it is a dual input module, choose 6 for Dual Input.
    5. Press Clear (*) Back repeatedly to exit program mode.
