To restore the primary alarm sensitivity settings:
1. Sign in with fire privilege 3, and then tap System Info on the Action bar.
2. On the Command bar, tap Toggle Alternate Sensing.
Setting the system date and time
The control unit incorporates a system clock to time stamp events and to activate time controls. The time is
presented in 24-hour format. The date format is determined by the 4-CU project property setting. The default
format is presented in month-day-year.
Note: Only users with fire privilege 3 can access this function.
To set the system date and time:
1. Sign in with fire privilege 3, and then tap System Info on the Action bar.
2. On the Command bar, tap Set Date Time.
3. Use the interface keypad to enter date and time.
The default format is YYYYMMDDhhmmss. Where,
YYYY = 4-digit year
MM = 2-digit month
DD = 2-digit day
hh = 2-digit hour
mm = 2-digit minutes
ss = 2-digit seconds
Note: The time is entered in 24-hour format, for example:
000000 = midnight
010000 = 1:00 a.m.
120000 = noon
130000 = 1:00 p.m.
235900 = 11:59 p.m.
The date and time, displayed at the top of the user interface screen, immediately changes.
Disabling and enabling devices
Disabling a device isolates it from the system. While the device is disabled, the EST4 control unit logs the status
change signals, but is prevented from processing the signals until the device is enabled. For example, the control
unit does not activate an alarm event when you activate a disabled detector, but it will after the detector is
enabled.
The control unit keeps track of how many times you disable a device without enabling it. You must enable a
device the same number of times you disable it in order to return the device to its original condition. The Status
Disabled report provides a counter that shows the number of times the device was manually disabled.
Notes
• Disabling the device address for a dialer or a dialer account deletes all event messages sent to that account
before they are transmitted. However, the dialer still transmits the account’s test-abnormal message and any
message that was in the dialer queue before the account was disabled.
