    Notes on operation and installation
    Planning by Dialock specialist is required.
    DT 400 FH door terminal modules must be installed by Dialock specialists after approval by the door manufacturer. If the terminal is installed without this approval, the Fire and Smoke Control Certificate for the fire resistant or smoke control door will be invalidated.
    Only to be used in combination with DIN mortice lock for DT 400. The comfort function is determined with the mortice lock.
    Spacer plateA spacer plate must be used if the distance between top edge of face veneer and lock case is less than 8 mm.
    Mechanical emergency openingDT 400 FH door terminal modules must always be equipped with a single profile cylinder for mechanical emergency opening. When using the mechanical emergency opening, please note the information sheet for determining the length of the single profile cylinder (operating instructions can be found in our online shop “”).
    Outdoor versionOnly the reader module is suitable for outdoor use. Please note the installation specifications for this version.
    The outdoor version must be approved by Häfele for the respective installation site. Installation sites with special conditions, e.g. saline environment, are not possible. Please contact your responsible Häfele employee when ordering the product.
    Battery change:The type-specific discharge behaviour (considerable voltage drop at the end of the life time) of lithium batteries may cause that a low battery is indicated at the terminal only for a short period or not at all. We recommend changing the batteries before the winter months with the outdoor version.
