Start-up: Check Sensor Zero

• After 90 sec. warm-up, the AreaRAE should display for all of the installed sensors

• If there is no alarm, and the sensor readings are in the range shown above, then the AreaRAE is ready for use.

Start-up: Check Sensor Zero

• If any reading is outside these limits, wait a few minutes then check again.– If readings are in limits use the unit– If readings are still outside these limits perform “Fresh

air calibration”

• Allows real-time, two-way wireless communication between AREARAE and base controller

– Continuously displays sensor data

– Shows alarm status when necessary

– Can send alarm to cell phones and pagers

– Can communicate back to the remote sensor with text messages

• With GPS option, displays location of individual remote monitors on map

ProRAE-Remote: Panel View

• Panel View: Displays status and alarm condition for all detectors in system

– Normal (no alarm) = green

– Alarm status (flashing red)

Normal Green indicator

ProRAE-Remote: Panel View

• Alarms: Simulated voice audible alarms along with visual alarms

Red “Stop Sign” Alarm Indicators

ProRAE-Remote: Status WindowStatus window: Shows current reading and history of each sensor for a specific AREARAE monitor

ProRAE-Remote: Status Window

Displays data from remote sensors: every sensor reading is updated at the master polling interval

Alarm Box: red text display shows pump is clogged

Alarm Command: Can send command to remote monitor to activate audible and visual alarm along with text messages to the display on the remote sensor(s)

ProRAE-Remote: Remote Alarm

• When hooked up to a phone line, the host computer can call any phone and provide a text message of the alarm status.

• The AREARAE system can be set up and left running without the requirement for an operator at the host controller at all times.

• This is particularly useful long term in security applications.
