Initial paper mdr was mailed to fda on (b)(4) 2015.An electronic follow-up was attempted but was not accepted on (b)(4) 2015.This electronic submission includes all initial and follow-up mdr data - submitted as a follow-up to mdr #9610483-2015-00002.(b)(4) 2015 initial: the lsu and the lsu wall bracket were returned to laerdal medical a.S.For evaluation on (b)(4) 2015.Testing of the ambulance's power source(s), wiring and voltage convertors has been requested.(b)(4) 2015 follow-up: evaluation: the returned laerdal suction unit (lsu) and lsu wall bracket were evaluated by laerdal medical as.An independent inspector has examined the generator used by this french ambulance company to power their ambulances while parked.The facility's generator was found to be operating erratically with its 240vac output varying between 100 and 400 vac.The facility has removed this external generator from service.Conclusion: the erratic over-voltage from the facility's generator caused a voltage surge suppression varistor component (located on lsu power board) to overheat and burn a small portion of the lsu and lsu wall bracket surrounding its external ac input power socket.The burning was localized to the lsu and wall bracket and the ambulance interior was only exposed to smoke/soot.The maximum continuous external ac input specified for the laerdal suction unit is 264vac and the varistor is rated for maximum continous input of 275 vac(rms).Due to this facility power failure the laerdal suction unit was exposed to an external ac power input that was well beyond its specified power limits.No faults were found with the lsu.
