ATS125x 4-Door DGP Installation Manual
The zone numbers in Table 6 on page 11 refer to the physical zone numbers on the
ATS125x PCB.
The system zone numbers relating to these functions for each of the ATS125x can be
found in Table 4.
Door numbering
Door numbers are determined by:
• The RAS or reader address when connected to the ATS system databus (doors 1
to 16).
• 4-door DGP address (doors 17 to 64).
Doors 1 to 16 are reserved for RAS 1 to 16 and are connected to the ATS system
databus. These only provide basic access control (door opening).
Doors 17 to 64 are used for door numbers and are controlled by a 4-door DGP
(ATS125x). These doors provide enhanced access control functions (such as anti-
passback).
