18. BM 25 BM 25 : batteries Pack of NiMH batteries (7V2/9AH), rechargeable without opening Autonomy = according to the configuration : Up to 170h operations non-stop Or for example 90 hours with explo/O2 and 2 toxic cells. Recharged in less than :4h30mn.

19. BM 25 BM 25 : remote power supply It’s possible to trickle the BM25 in a classified zone linked with «a remote intrinsic safety power » (with flammable and toxic cells only) For these reason,in this case and without alarm, the BM25 will work practically indefinitely !! But with alarm triggering,batteries will be discharged a bit.

21. BM25 BM25 : smart blocks 1 and 2= mini toxic or O2 smart block of cell 3= médium toxic or O2 4= EXPLO smart block of cell 5= médium or series 3/7 (new developments). 41 2 3 5 Note: without a block somewhere, take in place a dummy cell to keep the index of protection (IP66).

22. BM25 BM25 : smart blocks All the cells are: « plug in » easy connexion smart because fitted with a memory of characteristics (type of detected gas, unit, scale, sérial number, usure rate etc… Pre-calibrated Interchangeable.

23. BM25 BM25 : smart blocks Channel 5 can be fitted with either a medium cell or a big model (series 3) Note: BM 25 is fitted with 5 channels but can make a gestion of 4 only! For this reason if you use the channel N° 5, the 1 st will be automatically inhibited and the cell deactived ! 4 1 2 3 5

24. BM25 BM25 : explosible smart-blocks This channel is obligatory connected with a flammable cell for detection of major explo.gas and 2 types of cell can be used : catalytic or catalytic/catharometric.

25. BM25 BM25 : explosible smart-blocks « universal »: catalytic c ell Scale of measurement = 0 to 100% LEL « Non ambiguity measurement message » if the signal is tooà high > 100% LEL Choice of detected explo. gas (preprogrammed list) choice of a special type « all the gas »: the new cell, recently developped by Oldham, will indicate a correct concentration of the explo. gas detected whatever the type and in spite of a unic calibration with CH4 (different curves of explo. gases are very closed). catalytic/catharometric cell : Scale of measurement = 0 to 100%LEL / 0 to 100% gas/ volume with an automatic commutation of scale Note: to use this « LEL/volume » version, it’s obligatory to equip the BM25 with an oxygen cell !
