Resetting the System
Overview The function of the SYSTEM RESET key depends on whether active alarms are present at the time
the key is pressed.
• Active Alarms Present. Pressing the SYSTEM RESET key when alarms are present attempts
to return the system to its normal state. This includes resetting initiating devices (pull stations
and smoke detectors, for example), relays (including city relay and door holder relays),
notification appliances (horns and strobes), and all LEDs and indicators that have been
programmed to be reset with the SYSTEM RESET key. See “Resetting a System with Active
Alarms” below for more information.
• No Active Alarms Present. Pressing the SYSTEM RESET key when no alarms are present
causes the system to perform a hardware reset. See “Performing a Hardware Reset” below for
more information.
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 ALARMS LEDs flash. Press either the FIRE
ALARM ACK or the PRIORITY 2 ACK key or both, and the following message appears.
• If a zone or device remains in alarm and fails to reset, the “SYSTEM RESET IN PROG-
RESS” message is followed by the message shown below.
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 FIRE ALARM ACK (or
PRIORITY 2 ACK) key to review the points. (These points do not require acknowledgment.) The
ALARMS 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, for example, pull
stations with the handle down or smoke detectors with their LED lit.
