Serial Communications; Optional Serial Interface Boards; Prn Printers; Cabling And Connections - Notifier AM2020 User Manual

The AM2020/AFP1010 uses serial communication to move data between printers, CRT terminals and
annunciators. The various components used are described here.
Two optional serial interface boards are available for the AM2020/AFP1010. Only one may be used in the system, and
the particular board chosen depends on the specific needs of the installation. Refer to Figure 5.1-3.
SIB-2048A
The SIB-2048A has two printer and two terminal serial interfaces. The first printer interface supports a
PRN Fire Protective Signaling System Printer. The second printer interface is intended for connection to
UL 1950 Safety of Information Technology Equipment printers. The first CRT interface is for use with the
CRT or Fire Protective Signaling System listed terminal. The second CRT interface is intended for
connection to UL 1950 terminals.
The SIB-2048A ACS interface is electrically isolated. Devices connected to the annunciator control
interface may be used to activate modules (points) or display up to 2048 points/zones.
SIB-NET
The SIB-NET contains all of the features of the SIB-2048A. When used with a Media Interface Board
(MIB), the SIB-NET can also communicate with NOTI•FIRE•NET™. This allows the AM2020/
AFP1010 to transmit alarm and trouble events through the network to other network nodes for display
and recording. The network allows the NRT/INA to perform reset, acknowledge, and signal silence
functions at the AM2020/AFP1010. The SIB-NET replaces SIB-232, SIB-2048, and SIB-2048A in
existing systems which later require connection to NOTI•FIRE•NET™. The SIB-NET supports all
features of the SIB-2048A including ACS annunciators, printers, and CRTs.
The entire network must contain the same version of NOTI•FIRE•NET™ software. Improper
system operation will result if the versions are not the same.
All software part numbers are not compatible with each other. Improper mixing of software part
numbers can compromise life safety functions. If unsure about the compatibility of a particular
software combination, consult the factory.

Cabling and Connections

Male DB-25 connectors (Figure 5.1-1) are supplied with remote printers and display terminals. Use these
connectors to wire the interface between the peripherals and the Serial Interface Board (SIB) as illustrated in
Figures 5.2-1, 5.3-1, and 5.3-2.
