There are many installations with two or three MDS Digital Guard Units. If tenants want to use a different button to call each MDS Guard Unit, it is possible using an MDS Sensors Decoder.
Required material & software:
It is mandatory to use LOFT Extra Telephones with 3 buttons. Each button will call a different MDS Digital Guard Unit.
Door Open Button (blue) will always call the Main MDS Digital Guard Unit. F1 and F2 buttons will be configured to call the other two Guard Units.
F1 and F2 buttons of each telephone will be connected to one port of the Sensors Decoder 2429 (Group 0 and Group 1).
Cables form F1 and F2 should be connected to terminal “S” on the Sensors Decoder port. Negative port (“-“) is not needed to be connected.
Two Guard Units will be connected to the Accesses shifter 2379 and the other one directly to the MDS Digital Guard Unit.
Decoder Bus will start from the MDS Central Unit and will connect all the Audio Decoders 2424 and the Sensors Decoder 2429.
In order to have the same reference level, the negative terminal from al the power supplies on the installation, should be joined.
Guard Units Ref.2537 Configuration:
After installing all the devices and cabling process is finished, Guard Units address and mode have to be configured.
The Guard Unit has a number assigned, which must correspond to the number of the MDS switcher where it is physically connected. (0...9).
In this particular case, Guard Units will be configured as 1 (main), 2 (for F1) and 3 (for F2).
To change this number, which is 0 by default, keep the # key pressed until a question mark appears on the display. Enter the number of the desired Guard Unit, to which the system will respond with OK.
Once the Guard Unit number has been changed, the system must be rebooted so that the MDS Central Unit can recognize it.
Guard Units should be configured as Day Mode. Proceed first with Guard Unit 3, then Guard Unit 2 and finally Guard Unit 1.
How to select DAY MODE:
In Guard Unit number 1 will appear an “R” on the display. It means this Guard Unit will receive the calls when somebody press the Door Open Button in one Loft Extra Telephone.
Audio Decoder Ref.2424 Configuration:
Once the Guard Units are configured, it is time to program the Audio Decoder. It can be done using one of the Guard Units of the system. This is the procedure:
The display will show a series of dashes, depending on the User Code Length programmed into the system.
AB21AB: if display shows 6 dashes.
AB21A: if display shows 5 dashes.
AB21: if display shows 4 dashes.
The default value is 19025.When the code is entered correctly, the system goes to "Main Menu." If a wrong code is entered, the "Access Code" must be entered again.
Use this option to program the number assigned to each one of the telephones linked to the audio decoders installed in the system.
The systems asks you to press the decoder' "programming button."
Use a small screwdriver to press the programming button.
Telephone 1: 0101
Telephone 2: 0102
Telephone 3: 0103
Telephone 4: 0104
Sensors Decoder Ref.2429 Configuration:
Sensors Decoder have to be programed using the same procedure as the audio decoders (Steps 1 to 4). The only difference is the codes to be assigned to each sensor (Step 5).
In this particular case, the codes will be:
Following this configuration, Sensor Group 0 will be used to call Guard Unit 2 and Sensor Group 1 to call Guard unit 3.
The last step is to proceed with the Wincom+ Configuration.
