<F3> Key - Allows you to choose between Zone Coding and Zero Coding. In Zone
Coding a PNIS code for the tested zone is played (.e.g. Zone 12 is code 1-2). In Zero
Coding, two quick pulses (code 0) are heard. In both cases, when a fault is reported from a
zone, the signal circuits turn ON for 4 seconds.
•
<F4> Key - Enables/disables silent Walk Test™. When this key is pressed, it toggles the
system to audible Walk Test™, where the signal circuits are turned ON to play the codes
selected with the <F3> key, described above. Silent Walk Test™ is used in conjunction
with the logging function when audible signals might disturb the building occupants.
During the Walk Test™, the first line of the LCD shows changes, including the status of the
device under test. The second line of the LCD shows device status.
When the 4100 system is placed in Walk Test™ mode, any zone in the active Walk Test™
group(s) can be tested in any order. If zone coding is enabled, there is an advantage in testing
all devices within one zone before going on to the next zone.
You should simulate an alarm and fault condition for each device being tested. If you are
using an audible or visual indication, wait for it to clear before you test the next device.
Otherwise, wait for an appropriate amount of time (based on the system reset delay) before
moving on to the next zone. The LED on a smoke detector helps you in this area because it
indicates when the alarm is sensed, and when the detector resets. If zone coding is enabled,
verify that the code heard or seen is correct.
