    How to Program MUX Points on the DS9400 & 7024 Serires FACP


    I programmed Point Functions for several addresses  between 9-255, none of them are working.


    The panel does not look for addressable/mux points until they are programmed in MUX EDIT. The MUX EDIT programming defines what type of device belongs to what address on the multiplex buss. Panels with EPROM Revision 2.06 and higher offers an Auto Program Feature. This feature scans the bus for devices, when the devices are found it asks for the programmer to define what device is on each address.


    To Program a point in the panel.

    This menu is accessible only when the D7039 Multiplex Expander is installed.

    Use the MUX Edit option to add MUX devices to the system. Use the address switches to program each device with a unique address.

    • 0- NO DEVICE
    • 2- SINGLE INPUT (refers to the D7044/M, D7045, and D7052 [ Input loop as Class “A”])
    • 3- I/O MODULE (refers to the D7053)
    • 4- MUX SMOKE (refers to the D7050, D7050TH, and D343)
    • 5- SMOKE W/FRZ (not used)
    • 6- DUAL INPUT (refers to the D7052 [input loop as Class “B”])
    • 7- OCTAL INPUT (refers to the D7042/B)

    1. Press the number corresponding to the device you are adding, or press [0] if you are removing a device. When the device type is selected, the following window appears:
    2. Enter the address of the point being added and press [#]. The device type window appears again, allowing you to add more devices. Note that eight points are added at when the D7042 is edited into the control panel.

    Unprogrammed devices on the bus do not operate or are not supervised. Do not install more than one device programmed to the same address on the bus. Doing so can inhibit alarm reporting from both devices. Intermittent Trouble Reports from a particular
    MUX point address can indicate more than one device is programmed to that address. 


    To  Auto Program

    By scanning the buses for missing or new multiplex devices, this option allows the installer to configure the DS7400M to operate with the existing devices on the multiplex buses. The following display appears:

    Press [1] to continue auto programming or [0] to cancel. When you press [1], the D7024 checks for pre-existing programming errors where devices are incorrectly
    programmed in the space required for a lower addressed multi-point device, such as a dual point module. If a point is programmed under another device, the following error message appears for 5 sec, and the auto programming process aborts: If no errors are found, the D7024 begins a scanning process that takes approximately 1 minute to complete.
    When scanning is complete, the D7024 checks for missing devices. Missing devices are addresses with no devices on the multiplex buses, but programmed into the D7024’s site specific memory area. If missing devices are detected, the D7024 shows the following menu. (“xxx” is the missing device’s first point address): When Point Delete is complete, the D7024 shows the total number of points deleted from the control panel
    for period of 5 sec. “sax” indicates the number of points that were removed from the control panel's site-specific configuration.

    Missing Point Options
    Option When selected
    DELETE POINT - The missing point and any addresses it implemented (up to eight for an octal input module) are permanently deleted from the site specific memory area. If the deleted device is an I/O module, the output zones programmed for the relay reset to 0. If additional devices are found to be missing, the above display repeats for each missing
    KEEP POINT - The D7024 retains the programming for the current point and continues scanning for additional missing points.
    DEL REMAIN - The D7024 prompts with # KEY TO CONFIRM. If [#/CMND] is pressed, all
    missing points are deleted from the sitespecific memory area and the Auto Program process continues with the Devices Found Menu. If another key is pressed, the current point remains and the control panel continues scanning for additional missing devices.
    KEEP REMAIN - No additional points are deleted and the Auto Program process continues with the Device Found Menu. Points individually deleted with the Delete Point command before selecting the Keep Remain command remain deleted when Keep Remain is selected. Use the Delete Remaining feature with caution. Devices missing from the multiplex buses during the Delete Remaining operation, even momentarily, are permanently deleted. These points do not operate and do not generate trouble conditions even if they are returned to the bus. Verify that only the expected number of points were removed from the system. Points removed from the control panel's site-specific configuration do not operate and cannot be supervised even if they are returned to the bus. When Point Delete is complete, auto programming automatically checks for new devices on the buses. A new device is found when it is present on one of the multiplex buses, but its address is not programmed into the control panel's site-specific memory. If a new device is detected, the D7024 shows the following menu (where “xxx” is the address of the first new device found): This menu allows the device type to be defined. Press the number key corresponding to the device type installed at the address. If a detected device should not be installed and left inactive, press [0] to bypass the new
    device. All inputs are configured to use Point Function 10 as they are added. Points added during Auto Programming are not configured for the following operation:
    • Point Function 10 (Fire Alarm, Fast Response, Nonsilenceable, Not Local-only)
    • Open Status = Trouble
    • Output Zone 9
    • Alarm Verify = NO
    • Latching = YES
    You can change input point programming when Auto Programming completes using the Input-Programming Menu. When I/O modules are added during Auto Programming, the relay (second point) is configured to activate on any alarm, non-silenceable (Zone 63). You can change this when Auto Programming completes using the Output-Programming Menu. As new devices are added, the D7024 performs some basic error checks. The following errors can appear when adding a device: In the preceding message, “xxx” is replaced by the affected address, and “#” is replaced by a code number that indicates the type of error. Table 31 identifies the auto programming error messages. When the point-add operation is complete, the D7024 shows the total number of points added to the control panel for a period of 5 sec. Verify the number of devices added matches the expected number. Ensure the correct device type is selected for each point. Incorrectly specified device types can cause multiplex devices to malfunction or fail to operate.

    Auto Programming Error Messages
    Code Error Description
    1 New point is under an existing point. The new point is in the space required for an existing multiaddress device. This is checked when auto programming first starts.
    2 Point overlaps existing point. There are already devices configured at one of the addresses required for the new multi-point device.
    3 Point is at an illegal address. The addresses at which multiaddress devices can be installed are restricted.                                                                                                                      4 Too many multiplex relays. Only 20 I/O devices can be supported on a given bus. If a new device is not detected on the bus during the point-add operation, the device does not operate and does not generate trouble conditions even if it remains connected to the bus.

    When the point-add operation is complete, it shows the total number of points on the system (“xxx” is the total number of points, not devices). Verify the system shows the exact number of points expected. Points not included in the total count do not operate and do not generate trouble conditions. After the count of total points appears for approximately 10 sec, the D7024 restores the multiplex system to normal operation. This process takes approximately 50 sec, showing the following message during the
