14、40 min.4 FunctionalityThe telemetry system shall be capable of providing the following functionality:a) displaying the time of day on the base unit;b) time of whistle/warning;c) time to whistle/warning;d) elapsed time;e) remaining cylinder pressure measured in bar, and updated at intervals ofnot mor
15、e than 20 s for up to 20 portable telemetry units and two baseunits, and, for larger systems, intervals of not more than 60 s;f) notification to related base unit of any actuated distress signal;g) team and individual emergency evacuation of BA with acknowledgement;h) BA wearer withdrawal with ackno

17、ion 20145 Signals and acknowledgementThe telemetry system shall be capable of the following:a) receipt and acknowledgment of distress signals from related portable units;b) team and individual emergency evacuation of BA with acknowledgement;c) BA wearer withdrawal with acknowledgement;d) transmissio
18、n of a distress alarm signal (manual and/or automatic) from theportable telemetry unit to the base unit that the BA wearer is logged onto,indicating if they withdraw from an incident for reasons of personal safety;ande) transmission of a confirmation signal to the initiating portable unit inresponse
19、 to a distress alarm signal being received and acknowledged by theentry control board/base unit.In the event of a total evacuation, the system shall transmit a telemetry signalfrom the base unit to all logged on portable telemetry radio units. Thistelemetry signal shall trigger an audible alarm that
20、 is capable of being heard bythe BA wearers. The audible alarm shall be clearly identifiable or analogous tothe standard evacuation signal (e.g. the Acme Thunderer whistle1).In the event of partial or individual BA wearer evacuation, the system shalltransmit a telemetry signal from a base unit to se
21、lected logged on portabletelemetry radio units and cause an audible alarm.Distress alarm signals, BA wearer evacuation and withdrawal requests shall beindicated at their respective destinations within5sofinitiation. In the event ofcommunication failure, the portable/base unit shall repeat the origin
22、al requestat randomised intervals until it is successful.6 IdentificationPortable telemetry units shall have unique electronic identities that enable themto be individually logged on to a base unit at an incident.7 Data recording7.1 GeneralTelemetry systems shall be capable of recording data and thi
23、s data shall bedownloadable.The downloaded information shall include a timestamp (date and time) with aresolution of not more than 1 s.The data storage medium shall be nonvolatile and able to record at least8hofdata for every BA telemetry unit logged on.7.2 Data recordedThe following data shall be r
