The <SYSTEM RESET> key is used to return the system to its normal state
after an alarm condition has been cleared. When the <SYSTEM RESET> key
is pressed, it causes any latched circuits to reset automatically. Also reset are
initiating devices, relays (including the city relay), notification appliances, and
all LEDs and indicators which are programmed to reset with the
<SYSTEM RESET> key. The message, SYSTEM RESET IN PROGRESS,
is displayed when the key is pressed.
To reset the system, perform the following steps:
1. Restore/replace all affected devices in accordance with the instructions
provided with each device.
2. Press the <SYSTEM RESET> key.
If a device stays in alarm during the reset period, the system reset is aborted, and
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 <ACK> key to
review the points. These points do not require acknowledgment. The alarm
LED remains ON to indicate that a device is still in an alarm condition.
If the system does not reset, and the display still shows an alarm, read the display
to determine the type of device and the address of the device still in alarm.
Follow local procedures to investigate the area of the building with the alarm.
Look for devices still in alarm. Most devices latch until they are reset, either by
the system or manually.
