MN240-1 Rev C182.3 Safety and Alarm Features and Alarm Test ProceduresThe NewLife Oxygen Concentrator is equipped with an audible and visual alarm system.There are alarms for power failure, general malfunction, and low oxygen concentration.The alarm will remain on until the alarm condition is corrected, or until the power isswitched off. Refer to Section 6.3 for a list of probable alarm causes.A pressure relief valve is fitted to the compressor outlet and is calibrated to 280 kPA (40PSIG). Thermal safety is ensured by a thermostat situated in the stator winding of thecompressor (135°C / 275 °F).Three LED NewLife Units:Figure 1: Device warning label and alarm display. Note this is valid for unitsmanufactured January 1st, 2019 and later.Oxygen Monitor: In the event the oxygen monitor detects an oxygen concentration below82% the low oxygen concentration warning light ( ) will illuminate. If the low O2condition persists an audible intermittent alarm will also activate.Power Failure: In the event the unit is operating, and a loss of power occurs, the powerwarning light ( ) will illuminate and an audible intermittent alarm will activate.General Malfunction: If any of the conditions listed below occurs, the generalmalfunction light ( ) will illuminate and an audible intermittent alarm will activate. Thisincludes:• Obstruction to the flow of oxygen such as a pinch or kink in the delivery cannula,triggered by high product tank pressure **• High device product tank pressure condition of greater than 33 PSIG (±1)• Low device product tank pressure condition of less than 5 PSIG (±1)• High device temperature of greater than 135°C (275 °F), triggered by low producttank pressure if the thermal switch located within the compressor trips (shuttingdown the compressor)** Note: The indication for a “no flow” condition on the NewLife Elite and Dual FlowNewLife Intensity 10 models is the flow ball dropping to zero. There is no audible alarmindication for the “no flow” alarm condition on the NewLife Elite manufactured with 3LEDs. The Single Flow NewLife Intensity 10 model will display the general malfunctionvisual and audible alarm in the event of a “no flow” condition, caused by an obstruction tothe outlet port.Product Filter: ≥ 10 μm filterOne/Zero LED NewLife nits:
