1.3 DGP Expansion modules

The DGP expansion modules are system bus devices and are designed to expand the

system capabilities. The main task of the DGP is to connect faraway alarm zones,

providing a local power source and system outputs. The DGP idea encompasses also

access control expansions that enhance the system’s functionality in its work area.

Distributed intelligence philosophy allows systems configured from DGP and RAS

devices to cover a wide range of most complicated applications.

1.3.1.1 ATS1201 alarm zone DGP

8 alarm zones on board

32 alarm zones when maximally expanded

8 OC type outputs

16 outputs when maximally expanded.

High–current, monitored siren output

Integrated switched mode power supply 2,2A

Auxiliary battery back-up

M – ATS1641 housing

A type mainboard

The basic DGP device, providing remote ATS zone handling. Full support of the selected

area is provided by the integrated power supply (2A) with battery back-up feature, a

housing big enough to hold additional expansions, and an option of controlling a siren.

Note that this device allows the alarm system to take advantage of the whole range of

alarm zone addresses.

The configuration of the device is done via correct setting of the DIP switches.
