General Information
The DSX-1044 is an independent processing, 32 input,
intelligent controller designed to be a cost effective building
block in the DSX hardware platform that allows expansion in a
scalable manner. Up to 128 inputs can be controlled from 1
enclosure for an efficient space saving package. Each DSX-
1044 operates as a fully intelligent and independent controller
that retains all data necessary for system operation in its own
RAM. With its integral real-time Clock and Calendar it
performs Time Zone control with Holiday overrides for inputs
even when communication to the PC or other controllers is not
available. The DSX-1044 carries a Limited 2 Year Warranty.
Controller Architecture
The DSX-1044 Intelligent Controller may be used in
conjunction with all other DSX Controllers as a Master or
Slave in the controller network. Any controller may be
designated as a Master or Slave controller. The Master or
Slave mode of operation is determined by the panel’s dip
switch settings. The first panel of each location is designated
as the Master while all others would be considered Slaves.
The Master is responsible for communications to the PC and to
the Slave panels. Up to 64 Controllers can be used in a single
Location.
Up to four DSX-1044 controllers can be placed in a DSX-
1040E Enclosure along with a DSX-1040CDM
Communication Distribution Module. The controller can be
placed in a 1042PKG mixed with DSX-1042 and DSX-1043
Controllers. The DSX-1044 contains an AM186 processor,
512K of RAM, 512K of Flash ROM, and a Real Time Clock.
The DSX-1044 allows all door and field wiring connections to
be made via removable terminal blocks. The DSX-1040CDM
receives RS-485 communications from a possible previous
panel and regenerates the 4 wire RS-485 to the next DSX
Controller. The DSX-1040CDM also distributes Slave
Controller communication to those Slave panels located within
the same enclosure.
Inputs
The DSX-1044 has 32 Programmable Inputs. The armed status
of each input can be controlled by up to 4 Time Zones, I/O &
Card Linking, and Manually from the PC. Each input has its
own status LED that is on when the input is normal. Each
input individually supports 2, 3, and 4 state point monitoring.
Outputs
The DSX-1044 has 4 digital (open collector) outputs that have
the same programmability and functionality as all other DSX
outputs. The on/off state of each output is reflected by their
status LEDs. The outputs can be controlled by up to 4 Time
Zones, I/O & Card Linking, and Manually from the PC.
System Power
Each DSX-1044 is powered from an individually fused 12 volt
output from the DSX-1040CDM distribution module located
in the same DSX-1040E enclosure.
