15. Alarms Overview

The RigRat provides audible and visible alarm notification system, plus it combines local alarms on the
device with real-time remote wireless alarm notification to enhance worker safety. Local alarms include
audible buzzer alarm, visible alarm via bright LED lights, and an alarm notification on the display. The
audible alarm can be programmed or selectively turned on or off. The LED alarm indicators cannot be
turned off.

Alarm Signals

During each measurement period, the gas concentration is compared with the programmed alarm
limits for Low, High, TWA and STEL alarm. If the concentration exceeds any of the preset limits, the
alarms are activated immediately to warn of the alarm condition.
In addition, the RigRat alarms if the battery voltage is low.
When the low battery alarm occurs, it is recommended that you promptly charge the battery in a non-
hazardous location.
