General Alarm
Menus → System → General Alarm
The General Alarm triggers the buzzer, general alarm relay, general alarm icon, and
5X00 emails. Sensor and aux system alarms, slave failure (networks), low battery
alarms and ODO probe failure (ODO probe failure alarms apply to only 5500D-
01, 5500D-02 and 5500D-04 instruments) alarms trigger the General Alarm when
enabled. If individual system alarms are not enabled, the General Alarm will
not trigger.
The General Alarm (buzzer, relay, emails, icon) remains active until one of the four
softkeys
on the front panel is pressed. Pressing one of
the four softkeys while in the Run Screen stops the buzzer, de-energizes the General
Alarm relay, stops 5X00 emails, and removes the General Alarm icon. Pressing one
of these keys also resets the sensor and aux alarm systems. If the alarm condition
still exists after Alarm Hold period(s), the General Alarm triggers again. Low bat-
tery and slave failure alarms are not reset when softkeys are pressed.
Sensor alarm values set the acceptable control range. When a sensor reports a value
≤ low alarm value or ≥ high alarm value, the alarm system becomes active after the
alarm hold off period. See Senssor Setup section, Controls and Alarms - page 138
for additional information. If an alarm system is active and alarm relay is enabled,
the alarm relay energizes.
Notes:
- The Run Screen must be displayed during normal operation. All alarm
functions (5X00 email alarms, energizing of enabled alarm relays, alarm
icons, and buzzer) are suspended in 5X00 menus. Alarm systems are reset
when menus are exited to Run Screen.
- The General Alarm system is disabled during system-wide events such as
service hold and downloader.
- Sensor and Aux alarms must be enabled to trigger the General Alarm.
Alarm Hold Off
Menus → System → General Alarm → Alarm Hold Off→Time Units
General Alarm Hold Off is the length of time the alarm condition must exist before
the General Alarm system becomes active.
Notes:
- To avoid alarms for spurious events set the Alarm Hold Off > than 0.
- Aux system alarms are triggered after the Aux hold off time, and not after the
General Alarm hold off time.

- Low battery alarm has a five (5) second hold off that is not user selectable.
Relay
Menus → System → General Alarm → Relay
The General Alarm relay can be wired and configured for any output device to
energize when the General Alarm system is active.
Note:
- The General Alarm does not create an event log or control message regardless
if a General Alarm relay is enabled.
