SECTION 6
NETWORK INTERFACE
INTRODUCTION
The Network Interface Option allows the 4020 to communicate with other FA panels or with a 2120 Multiplex System
(see Network Concepts [NET-91 -5001).
Note: The 4020 acts as a transponder when connected to a 2120.
NETWORK (OR 2120) OPERATION DURING Walk Test’”
Status changes occurring as a result of a Walk Test’” operation in a networked system are not communicated to
other members of the network (or a 2120). The Walk Test’” is strictly a local 4020 operation. See Section 10 for Walk
Test’” procedures.
