Smoke Thresholds
With the LCD Programmer, the settings for choosing threshold levels based
on workdays and holiday periods cannot be used. Also, the cumulative alarms
setting cannot be used. The LCD Programmer enforces VLP threshold
ranges. VSC shall allow the VLF the full threshold range.

General Purpose Input
The General Purpose Input on the VLF detector is similar to the VLP, but does
not have the Inverted Reset setting. When using the Programmer, you should
not select an Inverted Reset for the GPI function.
If you select the Mains OK setting on the Programmer, the VLF detector's GPI
will be set to External mode.
Button Lockout
There are two specific front-panel buttons on the VLF, AutoLearn Smoke and
AutoLearn Flow which are not on the VLP. The lockout settings are not
available via the Programmer and can only be changed using VSC.
The button lockout function on the VLF locks out the function and not the
button. If a button has more than one function and only one function is locked
out the other function still operates.
Clearing the Event Log
Users are unable to clear the VLF detector's event log.
