18 Alarms Overview

The AreaRAE Plus/Pro provides an unmistakable four-way alarm notification system that combines local
alarms on the device with real-time remote wireless alarm notification (if the instrument is equipped
wireless functionality and it is active). Local alarms include audible buzzer alarm, visible alarm via bright
LED lights, and an alarm notification on the display. These can be selectively turned on or off.

18.1 Alarm Signals

During each measurement period, the gas concentration and radiation levels are compared with the
programmed alarm limits for Low, High, TWA, STEL, and other alarms, as applicable. If the
concentration exceeds any of the preset limits, the alarms are activated immediately to warn both the
AreaRAE Plus/Pro user and a remote safety officer (if wireless is enabled) of the alarm condition. In
addition to gas and radiation alarms, other alarms are available.
Furthermore, the AreaRAE Plus/Pro alarms if one or more of the following conditions occurs: battery
voltage low, pump blocked, PID lamp failed, etc.
When the low battery alarm occurs, there may be approximately 15 minutes of operating time remaining. In this
case, it is recommended that you promptly change or charge the battery in a non-hazardous location.

18.2 Changing The Alarm Mode

Your choices are Auto Reset and Latched. A latched alarm stays on until you acknowledge the alarm by
pressing a button. An auto-reset alarm turns off when the condition that set off the alarm is no longer
present (for instance, a high H
lowers below that threshold, turning the alarm off).
