« manual call point »FUNCTION

BM 25BM 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.

BM 25BM 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.

Note: without a block somewhere, take in place adummy cell to keep the index of protection (IP66).

BM25BM25: 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.

BM25BM25: 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 !

BM25BM25: 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 .

BM25BM25: explosible smart-blocks

• « universal »: catalytic cell

• 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 !
