Alarms and Notifications
Alarms notify the instrument operator of danger.Warnings notify of a condition that needs attention.
Take seriously all alarms, warnings, and indicators, and respond to each according to company policy.
Alarms
T40 II gas monitors have alarms of two different intensities, high and low.
Alarms are persistent:
they
turn off when the alarm-causing event is no longer detected,
however, if the instrument’s alarm latch is
enabled, an alarm will remain on until the user presses to turn it off.
When all alarm signals are on:
•
The high alarm features the red lights, with steady sound. It is fast-paced.
•
The low alarm is similar to the high alarm, but it is medium-paced.
Note: Signals (visual, audible, and vibration) vary based on instrument settings.
