The basic 4020 Fire Alarm Control Panel is capable of supporting system
expansion with peripheral cards. Although not discussed further in this
troubleshooting document, the following list shows some of the supported
expansion cards:
•
RS-232 Interface (Part No. 565-430) [supercedes 565-224]
•
Optional Mapnet Transceiver Interface (Part No. 565-241)
•
8 Point I/O (Part No.565-211)
•
Contact Closure DACT (Part No. 565-627)
•
Serial DACT (Part No. 565-629)
•
Multiple Network Option Boards (Part Nos. 565-277, 565-411, 565-518)
Most PCB assemblies in the system are assigned addresses for communication
with the Master Controller. The Standard Slave Card SW1 address switch is set
to device address 01, but the card also responds to Power Supply address 02 and
Mapnet Channel #1 address 03. The pre-designated 4020 System device address
assignments are listed in Table 2-1.
