Alarms - Thermo Scientific 1500 A2 Series Operating Manual

Section 4
Operation

Alarms

If the downflow, inflow or other parameters are not at operational settings,
there may be at risk of exposure to biohazardous material or
contamination. In this case, the biological safety cabinet emits a visual and
audible alarm to alert the user, as shown in Figure 4-23 below.
Figure 4-23. Alarming Screen for Downflow too high and too low Alarm
A "Health status" icon in the shape of an alarm bell appears on a red
background, along with a "Snooze" button.
Additionally, the "Health status" icon has a small blue circle overlay that
shows the number of pending alarms.
NOTE Applicable BSC standards in effect may not allow temporary muting
of audible alarm.
Tapping the "Snooze" button silences the audible alarm temporarily for a
pre-set timeout period. (The default alarm snooze timeout period is 5
minutes, but the setting may be changed in the "Alarms and Alerts"
screen, as explained in "Snooze Timeout"). The "Alarm bell" icon is
crossed out to indicate that the audible alarm signal has been snoozed
(Figure 4-24).
