2 SYSTEM DESCRIPTION
The AFP-2800/2802 is a microprocessor based distributed Fire Detection/Alarm System. The panel comprises
multiple microprocessors for sharing the processing load both within the panel and in the field modules using
proprietary communications protocols, thus the term “distributed system”.
The main panel communicates with the intelligent field devices via the RS485 communications ring. Each field
device can have multiple inputs and outputs. These inputs and outputs can include (but are not limited to) smoke
or heat detector circuits, bells and air conditioning controls.
The RS485 communications ring can support up to 100 distributed field modules and up to 50 panel annunciators
and 32 LCD80 units in terminal mode. The number of LCD-80s and modules on the ring will affect panel
performance and should be considered when designing the system.
In addition to the distributed conventional communication ring, the panel can support up to 10 loops of Analog
addressable points using various protocols including the proprietary Notifier FlashScan protocol. Each loop can
support 159 detectors and 159 modules.
In its maximum configuration, the AFP-2800 can support more than 802 Conventional Detection Circuits, more
than 400 Programmable Relay Outputs and 3,180 Analog addressable points. AFP-2802 supports a maximum of
396 Analog addressable points.
All of this data is stored in a large database and text based scripts are continuously processed to implement the
logic of input and output functions similar to a programmable logic controller (PLC).
The system’s configuration data and event history is stored in non-volatile “Flash” memory, which does not rely on
battery power for its backup. The operating system is also stored in flash memory so there is no need for EPROM
changes to upgrade the firmware.
Note: Loops 3 to 10
are only available on
