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 5200A emails, and removes the General Alarm icon. Pressing
one of these keys also resets the sensor and aux alarm systems. If the alarm condi-
tion still exists after Alarm Hold period(s), the General Alarm triggers again. Low
battery 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 Set Points, Control, and Alarms - page 128 for
additional information. If an alarm system is active and alarm relay is enabled, the
alarm relay energizes. See Aux Setup page133 for important aux control and alarm
system information.
Notes:
The Run Screen must be displayed during normal operation. All alarm -
functions (5200A alarm emails, energizing of enabled alarm relays,
alarm icons, and buzzer) are suspended in 5200A menus. Alarm
systems are reset when menus are exited to Run Screen.
The General Alarm system is disabled during systemwide events such as -
a Service Hold and a Firmware Download.
Sensor and Aux alarms must be enabled to trigger the General Alarm. -
