Description
TDA74xx Series are Ethernet and GPRS diallers that are
connected to the MI bus of an ATS control panel. The series
include the following diallers:
•
TDA7400: GPRS dialler
•
TDA7420: Ethernet dialler
•
TDA7440: GPRS and Ethernet dialler
Caution: The dialler is not compatible with other GSM/GPRS
diallers installed on MI bus, like ATS7310. Ensure that there is
only one GSM/GPRS dialler in the system.

DIP switch
DIP switch (item 5 in Figure 5) sets the DGP bus address. DIP
switch 1 is the least significant bit, while DIP switch 4 is the
most significant one. For example, DIP switch state "1101"
(where 1 is On, 0 is Off) defines bus address 11.
Caution: Before dialler address change ensure that the new
address is not occupied by a standard DGP, programmed in
the panel. Remove DGP from the panel database first.
Mounting
TDA74xx must be mounted inside ATS panel housing.
Figures 1 and 2 show mounting the dialler in Advisor Master
panels. Figures 3 and 4 show mounting the dialler in Advisor
Advanced panels.
WARNING: Electrocution hazard. To avoid personal injury or
death from electrocution, remove all sources of power and
allow stored energy to discharge before installing or removing
equipment.
To mount TDA74xx in an ATS control panel:
1. Place the clips in the square holes. Use fixed metal pillars
where available.
2. Mount TDA74xx using screws and metal washers.
3. Connect the earth tab to the earth connection of the
housing, if no metal clips or pillars are used.
Connections
Before applying power to TDA74xx:
1. Remove the battery wires that run from the battery to the
control panel.
2. Add the blue tap connectors to the red and blue (or black)
battery leads.
3. Connect the additional wires, which will be clamped to the
TDA module. See Figure 6.
4. Before clamping ensure that the battery leads will reach
the TDA module as well as the battery.
5. Connect the red wire to CON1+ and the battery.
Connect the blue (or black) wire to CON1− and the
6.
battery.
