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

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.
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.
Press the SYSTEM RESET key. The following message appears.
