3 Overview AreaRAE Inert can operate in two modes Standard AreaRAE (NORMAL Mode) AreaRAE Inert (INERT Mode) Specifically designed for use in low-oxygen (inert) environments Three major differences from the NORMAL mode LEL sensor is disabled PID sensor readings converted to % LEL Octane equivalents default Custom default sensor alarm settings

4 AreaRAE Inert Monitor Features 5 internal sensors Photoionization Detector (PID) O 2, LEL 2 Toxics Optional GPS Built-In MHz RAELink modem Frequency hopping, spread spectrum Up to 2 miles / 3.2 kilometers

5 AreaRAE Inert Monitor Sensors Oxygen: 0-30% Combustibles: 0-100% of LEL Disabled in INERT mode Toxic sensors: CO, H 2 S, SO 2, NO, NO 2, Cl 2, HCN, NH 3, PH 3, HF, HCl VOC monitor: PPM in NORMAL mode 0.1%-19.9% LEL in INERT mode - (0.02%) resolution

6 AreaRAE Inert Monitor Features Large LED display and alarm light Loud 110dB buzzer (10cm) can be muted Strong 500 cc/min Sampling pump 4-Way power Li-Ion rechargeable battery Alkaline battery 120 / 240 VAC 12 VDC Intrinsically safe Class I, Division II, Groups A, B, C, D

7 AreaRAE Inert Monitor Features Long Run time: 18 hrs w/li-ion, 9 hrs with Alkaline *Continuous operation via AC power Rugged Housing: IP53 for water and dust resistant Withstands 1 meter drop Size: 9.25" L x 5.0" W x 9.25" D Weight: 8.5 lb. with battery pack Temperature Range -4oF to 113oF -20oC to 45oC *If the application hazardous area certification regulations allow it, the detector can run continuously using AC power

8 AreaRAE Inert Monitor Pump Makes remote sampling easy Sample draw up to 100 feet! Always use external filter for added protection Pump stall feature: When moisture is detected or when pump is blocked the pump will shut off ~300cc/min at Low flow, ~550cc/min at High flow Only use Teflon tubing

9 AreaRAE Inert Start-up: Turning On Hold MODE Key to turn on (alarm will beep once) Watch display screen for messages such as: Sensors installed & their warranty expiration Alarm limits Last calibration date User/Alarm/Datalog modes *Warm-up will take approximately 90 seconds

10 AreaRAE Inert Start-up: Warnings TOX1 VOC TOX2 Incorrect Year LEL Check Clock!!! OXY If this screen appears during the start-up just acknowledge it with the Y key and follow the procedure for setting the clock. The battery has gone dead and the AreaRAE has detected a mismatch between the date code on the sensors and its internal clock.

11 AreaRAE Inert Start-up: Warnings TOX1 VOC TOX2 O2 Installed LEL Warranty Expired OXY This is a warning screen. As long as the sensor calibrates properly it is valid to continue using it. Acknowledge by pressing the Y key to continue warm-up. For maximum AreaRAE availability, RAE Systems recommends replacing sensors at the end of their warranty period

12 Start-up NORMAL Mode After 90 seconds warm-up, the AreaRAE should display all sensors installed If there is no alarm, and the sensor readings are in the range shown above, then the AreaRAE is ready for use

13 Start-up INERT Mode If the detector was shut off in INERT mode, the unit will start up in INERT mode LEL display is replaced with INRT CO display is replaced with COH2 VOC display changed from ppm to %LEL Resolution of 3 decimal places instead of 1 NOTE: When the AreaRAE Inert is turned on while in INERT mode, and its alarm is sounding, it is likely that the normal oxygen level of 20.9% in fresh air is causing this.

14 Switching Operation Modes Menu options allow switching between NORMAL & INERT mode -Press MODE to scroll through menu options NOTE: Unit will always start up in the mode it was in when shut down

15 Wireless Mode Display A small radio antenna displayed in the left center of the AreaRAE screen indicates that the wireless link is established

16 GPS Mode Display A small satellite displayed in the left center of the AreaRAE screen indicates that the GPS is communicating. A minimum of 3 satellites is needed for good signal The display will show a max of 4 satellites GPS on but no satellite signal =

17 Datalog Mode Display A small L is displayed in the left center of the AreaRAE screen indicates datalogging Will datalog 20,000 points (64 hrs, 5 channels, 1 min interval) User can choose one of 4 datalog modes (Manual, Automatic, Periodic & Scheduled in ProRAE Suite)

18 AreaRAE Inert Start-up: Lamp Alarm Lamp display along with audible alarm indicates that PID lamp has failed to light Press Y/+ key to clear alarm, if it clears AreaRAE is ready for use If alarm does not clear, wait a few minutes and check again

19 AreaRAE Inert Start-up: Lamp Alarm If after a few minutes the Lamp message remains, turn off AreaRAE and restart If after restart Lamp message disappears, AreaRAE is ready for use If after restart Lamp message remains, the PID Lamp needs service

20 AreaRAE Alarms: Pump Pump display along with 3 beep audible alarm indicates that pump has stopped due to line clog Pump alarm is a latching alarm Clear line/filter and press Y/+ key to clear alarm and restart pump

21 AreaRAE Alarms: Low Battery A flashing Bat display along with a 1 beep alarm every 10 seconds indicates that the battery voltage has dropped below 6.2 V and it will shut down in minutes Quickly complete confined space entry and charge AreaRAE or install alkaline battery

22 AreaRAE Inert Start-up: Pump Check Every time the AreaRAE Inert is used it is important to check pump flow: Block the filter on the pump inlet Reset pump alarm by pressing the Y key If pump does not go into alarm, check for loose/cracked filter or service pump

23 AreaRAE Inert Start-up: Bump Test Periodic functional testing of the sensors by doing a bump test is recommended Defined as a brief exposure of the monitor to the calibration gas and the sensors to show response and trigger the lowest alarm set point for each sensor The monitor should be calibrated if it does not pass a bump test, but no less than every 6 months, depending on use and exposure to gas and contamination Always operate monitor with external filter It is recommended to keep the units on charge when not in use

24 AreaRAE Inert Alarm Signals The AreaRAE will provide audible and visual alarms to alert users to unsafe states It is extremely important to note that during the following conditions the alarm signals are disabled: When entering the Communicate with PC? standby mode. When entering the Calibrate Monitor menu When viewing data in the View or Change Datalog? menu

25 AreaRAE Inert Alarms: High AreaRAE Inert unit operating in NORMAL mode with VOC High Alarm of 102 ppm High display along with 3 beat/second audible/visible alarm and flashing display backlight indicates that the high alarm has exceeded VOC sensor (PID) has high alarm setpoint of 100 ppm default in Normal mode Press Y/+ key to clear if latching alarm

26 AreaRAE Inert Alarms: Low Low display along with 2 beat/second audible/visual alarm and flashing display backlight indicates that Oxygen sensor has gone into low alarm All other sensors, Low alarm indicates the first warning Press Y/+ key to clear if latching alarm

27 AreaRAE Alarms: STEL & TWA Short Term Exposure Limit (STEL) & Time Weighted Average (TWA) alarms are available for toxic sensors and for PID in NORMAL operation mode If either alarm is exceeded, STEL or TWA is indicated for sensor in alarm, along with a 1 beat/second audible/visual alarm STEL alarm will only clear after 15 minutes in clean air or the AreaRAE is turned off! TWA alarm will only clear after moving to clean air and then turning off the AreaRAE

28 INERT Mode Alarm Levels LOW HIGH STEL TWA CO 35 ppm 200 ppm 100 ppm 35 ppm H2S 10 ppm 25 ppm 15 ppm 10 ppm LEL NA NA NA NA O2 0.5 % 5 % NA NA PID* 1000 ppm = 10% LEL 1500 ppm = 15% LEL NA NA *Octane equivalents

29 NORMAL Mode Alarm Levels LOW HIGH STEL TWA CO 35 ppm 200 ppm 100 ppm 35 ppm H2S 10 ppm 25 ppm 15 ppm 10 ppm LEL 10 ppm 20 ppm NA NA O % 23.5 % NA NA PID 50 ppm 100 ppm 25 ppm 10 ppm

30 Alarms: LEL OFF When operating AreaRAE Inert in NORMAL mode: OFF display along with a 3 beat/second audible/visual alarm indicates that LEL sensor has been exposed to too much gas and has shut off to protect the sensor. Move the meter to clean air and press the Y key to reset.

31 Alarms: NEG NEG display along with a 1 beat/second audible/visual alarm indicates that a sensor has drifted negative (below zero) because the sensor was zeroed in an area containing gas. Perform Fresh Air Calibration in an area clear of all gases.

32 3 User Modes Normal Mode has different privilege levels or User Modes Program Mode: 11 screens for most advanced users Display Mode: 7 screens and has password to get into programming (default mode) Text Mode: 3 screens and has password to get into programming
