ATS125x 4-Door DGP Installation Manual 7
ATS system databus connection
The system databus is used to connect DGPs (such as ATS125x) and arming stations
to the ATS control panel. Remote devices can be up to 1.5 km from an ATS control
panel.
Each remote device is assigned an address and is polled in sequence by the ATS
control panel. Up to 12 4-door DGPs can be connected on the main ATS system
databus.
Arming stations and DGPs must be connected via a two-pair twisted shielded data
cable from the system databus connection (WCAT 52 is recommended).
Connect the shield of the data cable to earth at the ATS control panel. It should be left
disconnected at the other end.
The 4-door DGPs have their own built-in power supply and do not require power from
the databus. Only the D+, D− and 0 V connections are required between the ATS
control panel and a 4-door DGP.

ATS125x local databus and earth connection
The ATS125x allows for 16 arming stations (LCD remote arming stations, Smart Card
readers) to be connected to the local databus (CON9/CON10).
The ATS125x local databus consists of two electrically independent loops. If there is a
failure in one loop, the other loop can still communicate with the remote devices. The
location of devices on the first or on the second loop has no influence on the
functionality, as both loops behave as one databus.
Wire the door contacts and request-to-exit buttons associated with each door to the
ATS125x inputs.
Any zone used for DOTL (door open too long) cannot have any wiring connected.
Each unit is assigned an address and is polled in sequence by the ATS125x on each
loop. Remote units can be located anywhere up to 1.5 km from the ATS125x. Each
loop must have termination on both ends.

DIP switch settings
DIP switches 1 to 4 (DGP address) are used to identify a DGP to the Advisor MASTER
control panel, i.e. to assign the DGP address. A 4-door DGP can only be addressed, as
DGPs 1 to 12.
DIP switches 5 to 6 are used for zone expansion configuration.
DIP switches 7 to 8 are not used.
