The Alarm Zone Controller (AZC) is an alarm monitoring field
device for use with MDI’s Integrated Digital Controllers. The
AZC functions as an interface between the alarm input devices and
the Network Local Controller (NLC) / Communications Board (COMM). |
The
AZC features 16 supervised inputs and 4 relay outputs. Application programs
(firmware) and zone configurations are downloadable into FLASH MEMORY
eliminating the need to physically replace EPROMs for application changes
and system upgrades.
During
loss of communications to the NLC/COMM, the AZC continues to monitor alarms
and store events in a high capacity buffer. When communications is restored,
the buffered events are transmitted to the host. Industry standard RS-485
communications protocol is used between the AZC and COMM/NLC.
The
MDI system design is scalable, which provides for reduced installation
costs. As customer needs change and grow, additions to the system become
cost-effective by simply reconfiguring the system or adding only the required
controllers.
