Honeywell AreaRAE Plus, User Manual

Page: 124 / 145

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 with 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.
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.
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
2
S reading that exceeds the preset threshold
and triggers an alarm, but then lowers below that threshold, turning the alarm off).
1. Enter the Alarm Mode sub-menu of the Alarms section under the Programming Menu.
2. Select Auto Reset or Latched by pressing [N/-] to select the mode, and [Y/+] to confirm
the choice.
3. Press [Y/+] to save your selection.
