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.
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.
• 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.
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 -- pull stations with the handle down, smoke
detectors with their LED lit.
