How do I perform a walk test on the NFS2-640?
To perform a walk test on the NFS2-640, you must first ensure the panel is not in an alarm condition, as the test cannot be initiated during an active alarm (Page 50) [1].
-
Navigate to the Status Change menu and select Walk Test (Page 50) [1].
-
For a Basic Walk Test, press ENTER to start; for an Advanced Walk Test, enter LTEST at the password screen (Page 50) [1].
-
Activate input devices; FlashScan devices will blink their address (e.g., 8 blinks for address 8) to confirm communication (Page 51) [1].
-
In Basic mode, silenceable outputs activate for approximately 4 seconds for alarms and 8 seconds for troubles (Page 51) [1].
-
In Advanced mode, all mapped Control-By-Event (CBE) logic activates, excluding releasing functions (Page 50) [1].
-
Review results in the History buffer by pressing ENTER, then 2 twice, then ENTER from the System Normal screen (Page 52) [1].
