Deployment 5 Deployment Deployment is the process of placing detectors and HUB(s) throughout the work site and to be used in an operational state. With the exception of the AC connector for the HUB, all other components are able to operate in hazardous locations. The detector and HUB must be oriented upright and should avoid direct sunlight if possible. Detectors must have SensorShield and SunShield installed during deployment. Detectors must be oriented as shown below: 5.
Deployment A detector must be within the range of the HUB in order to be a part of the network. Under ideal line of sight conditions, the range is up to: • 915 MHz radio: • • HUB to detector: X meters (X feet) • Detector to detector: X meters (X feet) 868 MHz radio: • HUB to detector X meters (X feet) Detectors that are out of range of the HUB are able to make up to two hops through neighboring detectors to extend the range.

Operation 6.1.
Operation 6.1.4 Detector LED Definition Use the combination of the LEDs and detector display to evaluate the state of the detector.
Operation 6.2 Sensor Alarms If the gas concentration reaches or exceeds the alarm set point, the detector will alarm. There are two alarm levels: low alarm and high alarm. 6.2.1 Sensor Missing Alarm The detector alerts the Sensor Missing alarm if the detector detects that the sensor is not properly installed in the detector or is not functional. During power on, if a sensor is detected as missing, the detector display prompts the user of "Sensor Change?".
Operation 6.2.4 Exceed High and Low of Sensor When a gas reading exceeds the full scale range of the sensor, the detector displays can "XXX" or "+++" in place of the actual reading. When a gas reading falls below a defined under-range threshold, the detector displays " ---" in place of the actual reading. For combustible sensors, the sensor reading is in in locked alarm. The sensor reading is in over-range. The sensor reading is in under-range.
Operation 6.4 Monitoring Combustible Gases The detector has been optimized for a response to Methane. The detector can monitor these concentrations in ambient air: Gas Type Methane Propane Hydrogen Acetylene Response Factor 1 1.4 1.1 1.2 The detector displays the combustible gas concentration in % LEL or % Vol CH4 on the Measuring screen until another screen is selected or the detector is turned off. WARNING! A combustible gas reading of "100" or "5" indicates the atmosphere is above 100 % LEL or 5.
Operation 6.
Calibration and Bump 7 Calibration and Bump WARNING! Detectors will not be performing hazardous gas sensing operations while calibrating. Failure to follow this warning can result in serious personal injury or death. The detector must equilibrate to room temperature before bump or calibration. Calibration Certification All applicable inspections, testing, and calibrations were performed using NIST traceable equipment, where available, in accordance with MSA's ISO 9001 Certified Quality System. 7.
Calibration and Bump CSA requires (per 22.2 NO. 152) that combustible sensor sensitivity be tested before each day's use on a known concentration of methane equivalent to 25 to 50 % of full scale concentration. ACCURACY MUST BE WITHIN 0 to +20 % OF ACTUAL. Correct accuracy by performing the calibration procedure described in section 7.2.1 "Calibration". 7.1.4 Equipment See section 13.1 "Detector Spare Parts and Accessories" for ordering information of these components: 7.
Calibration and Bump (4) Tap the Bump RFID tag in Calibration Cap to the button. Once prompted, a detector will display 'Install Cap', at which time Install the calibration cap.

Calibration and Bump After bump completes, the detector will: Pass: • Beep • Display green LEDs • Display check mark and “Bump Pass“ text Fail: • Beep • Display red LEDs • Display “X“ and “Bump Fail“ text If the detector fails, the detector will automatically attempt a second bump test. (10) Turn off gas. WARNING! Do not continue operation of a detector that is not able to pass a bump test. Failure to follow this warning can result in serious personal injury or death. (11) Remove Calibration Cap.
Calibration and Bump (13) Install SunShield on detector. 7.2.1 Calibration Calibration must be performed using a flow regulator with a flow rate set to 0.25 liters per minute. Under normal circumstances MSA recommends calibration before each deployment. Please check your national legislation. Calibrate at room temperature. Allow detector(s) to stabilize for 30 minutes before calibration. Stated calibration performance is for room temperature. Equipment For Part Numbers, see section 13.
Calibration and Bump Calibration Steps (1) Remove SunShield. (2) Remove SensorShield with the detector exposed to fresh air. NOTE: If uncertain, use a bottle that contains fresh air. (3) Press button on the detector to enter interactive mode. (4) Tap the Cal RFID tag in Calibration Cap to the button.
Calibration and Bump Once the Cal RFID tag is read, a Zero calibration will initiate Screen will display 'Zero Test' and LEDs will flash blue. NOTE: Do not install the Calibration Cap during Zero Calibration! After Zero calibration completes, the detector will: Pass: Check mark and 'Install Cap' text are displayed. Fail: • Beep • Display red LEDs • Display 'X' and 'Zero Fail' text During zero calibration the O2 sensor is also span calibrated to 20.
Calibration and Bump (4) Open valve on regulator to allow gas to flow to the detector. The duration of the application of the calibration gas is controlled by the detector. The detector will indicate that calibration span has successfully passed and that the gas can be removed.
Calibration and Bump (7) Install SensorShield on the detector. (8) Install SensorShield. WARNING! A SensorShield must be installed on detector(s) in all situations where the detector(s) may be subject to conditions that could lead to blockage of the sensor path (including, but not limited to, rain, water spray, dusty or dirty environments, snow and ice storms or icing conditions).
