LW-401
Last Event Record (Test Level 4)
This feature records the zone in which the
last event occurred in each of four catego-
ries: Alarms, Troubles, Verified Alarms, and
Supervisories. This can be used for trouble-
shooting one-time reports of events.
Program Mode
The program mode allows the user to
change the configuration of the LW-401
system. The program mode has nine levels.
Each level allows the user to configure a
different function within the LW-401.
When the program mode is enabled, the
current programming levels and sublevels
display in turn on the seven segment display.
The order of the display is as follows:
1. the program level is displayed first
2. then a hyphen (-) is displayed
3. then the sublevel is displayed
4. then the display is blank.
The entire sequence then repeats.
In the programming mode, the four function
keys operate differently than they do in the
normal mode. Their functions are as follows:
The Acknowledge key toggles between the
Test mode, the Program mode, and the
Leave mode. The seven segment display
shows t, P, and L, respectively, to indicate
these modes.
The Reset key is used to select program
levels and options inside the programming
levels.
The Drill key selects options and toggles
options on and off.
The Silence key selects different sublevels.
Pressing silence when the seven segment
display shows L exits the user from the
program/test mode.
