A.3.3 How to View Holiday Function Selections
You can use the Read Status Entry option to view the current selection for the Holiday function. To
do so, press the following keys in sequence:
The LCD display in Figure A.5 gives an example of an LCD display of a Holiday function:

A.3.4 How Time Control and Holiday Functions Work
Time and Holiday activation occurs automatically and does not require operator intervention. All
outputs with a CBE list containing F5 or F6 activate within the times specified for the days of the
week listed in F5 or F6. All smoke detectors with a CBE list containing F5 or F6 switch to their
lowest sensitivity (AL:9) within the times specified for the days of the week listed in ZF5 or ZF6.
Refer to “Intelligent Sensing Applications” in the
NFS2-640 Programming Manual
for details on
setting detector sensitivity.
Time Control is active for all days of the week listed in F5 or F6. Holidays listed in F7 are excluded
unless you list Holidays (H) in the day-of-week selection of F5 and F6 (shown in Figure A.4). Enter
the time functions in a 24-hour format with the OFF time later than the ON time. After changing
programming using Time Control, always reset the control panel.
You can use Time Control zones F5 and F6 to program non-fire applications such as turning lights
on and off, setting a thermostat, and so on. For example, you can program zones F5 and F6 to
activate outputs at one time of day and deactivate outputs at later time, on specified days of a week.
Table A.3 contains descriptions of additional Time Control applications:
NOTE:
For instructions on programming the Holiday function, refer to the
NFS2-640
Programming Manual.

Application
Requirement
Control day and night sensitivity of
intelligent, addressable detectors
List zone F5 or F6 in the detector CBE. This
automatically sets the detector sensitivity to the
minimum setting (AL:9) during the day and
automatically returns detector sensitivity to
programmed sensitivity during the evening.
Control a specific date of year
Input up to nine date in the Holiday selection screen
for Special Zone F7, then list zone F7 (Holiday) in the
CBE of a device.
