4.4.1 Resetting a System with Active Alarms
Activated devices (i.e, devices in alarm) can be reset, using the SYSTEM RESET key. Doing this allows the system to return to a normal state
following alarm activation. Follow these steps to perform a system reset when alarms are present.
1.
Press the SYSTEM RESET key. The following message appears.

2.
One of the following occurs, depending on whether the activated devices reset or not.
• If all zones or devices in alarm reset, the SYSTEM ALARM LED flashes. Press the ALARM ACK key, and the following message appears:
Figure 16: Normal Operation Text Screen
• If a zone or device remains in alarm and fails to reset, the "SYSTEM RESET IN PROGRESS" message is followed by the message shown
below.
Figure 17: Alarm Present Information Box
When this message appears, the system remains in an alarm state. The display indicates the total number of alarms present in the system
along with a prompt to use the ALARM ACK key to review the points (these points do not require acknowledgment.) The SYSTEM ALARM
LED remains ON to indicate that a fire alarm device is still in the alarm condition. Read the display to determine the type and location of
the device. Follow local procedures to investigate the area of the building in alarm. Look for devices that are in an alarm state like pull
stations with the handle down, or smoke detectors with their LED lit.
