2.3.3 Alarm Status Menu

When the MSG button is displayed, it indicates that one or more warnings have been issued. To view the warning messages, press the MSG button. Repeatedly pressing this button will cycle through all available warning messages. Pressing CLR will clear the warning message from the display. Note: If the conditions that caused the warning messages are still in effect, the warning messages will re-appear after they have been cleared.

The ALRM button is displayed when concentration alarms have been triggered. See Section 2.3.3 for operation of the Alarm menu.

2.3.3 Alarm Status Menu

Pressing the ALRM button from the main menu when alarms have been triggered will bring up the alarm status menu as shown below in Figure 2.3.

	ALARM STATUS			HI=ACTIVE, HI HI=OK

	CLR				BEEP		EXIT

FIGURE 2.3 - ALARM STATUS MENU

Clearing Alarms

If the monitor is configured for Latching type alarms, and either of the alarms can be cleared (ie. The concentration has dropped below the alarm threshold,) then a CLR button will appear as shown in Figure 2.3 above. The CLR button will clear the alarm condition.

If the monitor is configured for Non-Latching alarms, the CLR button will not appear, and all alarms will automatically clear when the concentration drops below the alarm threshold.

Audible Beeper

An audible beeper is sounded when any alarm is activated. A slow beep indicates that the ‘HI’ alarm has been triggered, and a fast beep indicates that the ‘HI-HI’ alarm has been triggered. Pressing the BEEP button from the alarm menu will silence the audible beeper for 5 minutes. Note: Pressing the BEEP button does not clear any of the alarms, it simply silences the audible alarm. If the alarms are not cleared, the audible alarm will automatically resume in 5 minutes.

See Sections 3.1 and 3.5 for details on configuring concentration alarms.
