9.6.2 Time Options
Through this programming option you can set the water flow delay time, alarm verification time, AC report delay, AC-Frequency, Auto-
Resound, and Clock Format.
Water Flow Delay
You can program a delay of 0-90 seconds (zero means no delay) to be used in conjunction with a water flow switch. The delay is system-
wide. All water flow switches on the system will use the same delay period.
To access the screen for programming water flow delay, follow these steps:
1.
Enter the installer code. The panel will automatically go to the main menu.
2.
Select 7 for Program Menu.
3.
Select 5 for System Options.
4.
Select 4 for Time Options.
A screen similar to the one shown in Figure 9.10 will display.
5.
Enter the number of seconds (0 to 90) to delay an a water flow switch alarm, then press ENTER.
Alarm Verify
You can set the alarm verification time from 60 to 250 seconds (default is 60 seconds).
To set the alarm verification:
6.
Enter the desired number of seconds for the alarm verification time.
7.
Press the right arrow or ENTER to make your selection and move to the next programming option.
AC Report Delay
NOTE: You must select 1-3 hours in UL central station installations and UL remote signaling installations.
You can adjust the number of hours before a low AC report will be sent to the central station.
To program low AC report delay, follow these steps:
8.
Enter the number of hours (0-30) before a low AC report will be sent to the central station, then press ENTER.
Change AC Line Frequency
The panel's AC line frequency is selectable for 50, 60 Hz, or Internal. AC Frequency feature dictates how the control panel will calculate
time based on the AC line frequency used in the installation site. The "Neither" option can be used in areas where the AC line frequency
is not dependable and you want the panel to calculate time from the internal crystal. The internal crystal is not as accurate as the AC
power source and internal 60 Hz or 50 Hz should normally be selected. The panel defaults to the 60 Hz. selection.
To change the AC line frequency, continue programming from step 9 above:
9.
Select 50, 60 or Intl by pressing the up or down arrow, then press ENTER.
Clock Display Format (AM/PM or Military)
To change the system clock display format:
10. Select AMPM (for AM/Pm display format) or MIL (for military or 24 hr display format) by pressing the up or down arrow, then
press ENTER.
Auto-Resound (4 or 24 hours)
The system resound time period can be modified from the default value 24 hours to 4 hours. This setting adjusts when the FACP will
automatically resound events after being silenced. Set this option to 4 hours when using SWIFT devices
