Pre-Alarm Operation (AWACS) 3. Operating Modes
AFP-300/AFP-400 Operations PN 50260:C1 05/22/97 11
Pre-Alarm Operation (AWACS)
Note: Refer to the AFP-300/
AFP-400 Programming manual
for more information on
AWACS applications.
If an SDX or CPX detector exceeds the programmed Pre-Alarm level, a Pre-Alarm
condition occurs: the panel sounder and zone F9 activate; and the Pre-Alarm LED
lights. Figure 8 shows a sample Pre-Alarm message—sent to the LCD display, optional
LCD-80, optional printer, and history file—for a control panel programmed for an Alert
Pre-Alarm.

automatically restore.
If programming a control panel for an ACTION Pre-Alarm, the display remains the
same, but the word “Action” replaces “Alert”. The control panel latches for ACTION
Pre-Alarms and applies the programmed control functions.
Time Functions
Overview The control panel includes a real-time clock that provides time-of-day, date, and day-
of-week. The clock includes a lithium battery backup. Time normally displays in a
12-hour time format with month/day/year. Table 8 contains descriptions and typical
uses for time functions.

Description Typical Uses
Time Control
Command
Zones F5 and F6 are reserved for
control-by-time special functions,
intended for ancillary (non-fire)
applications (such as lighting
control, setting a thermostat, and so
forth).
For example, program zones F5
and F6 to activate at one time of
day and deactivate at another time,
on certain days of the week. You
can turn a non-fire control point on
and off, by using zone F5 or F6.
Day/Night
Sensitivity
Adjust
If a CPX, SDX LPX, or IPX
detector CBE lists zone F5 or F6,
the control panel sets the detector
sensitivity to the minimum (low)
setting when zone F5 or F6 is
activated by the programmed date/
time in its CBE. When zone F5 or
F6 deactivates, the detector
sensitivity returns to the
programmed setting.
For day/night sensitivity use,
consider zones F5 and F6 as Day
zones.
Holiday The control panel reserves zone F7
for setting holiday dates (up to 9
days). When the current date
matches any of the nine holiday
dates, the control panel activates
zone F7.
Other uses for zone F7 include: a
special day-of-year control; or an
8th day in programming zones F5
and F6.
