BM 25BM 25
STAND ALONE DETECTOR:
BM25BM25• Rugged
• Has been specially designed for operation in harsh and corrosive environments
• High visibility and audible alarm• Fitted with a large flashing red LED
module • and 2 « loud hooters » : 103db/1m.
Safety in the field
• Designed for team protection:rescue teams…
• Area surveillance for mobile or short term works
• Used where fixed detection systems are inapropriate or not present
BM25BM25 = rugged MX 2100 version
• Keep the MX2100 characteristics and other new functions :
• a new king of cells «serie 7/3 » • programmable relay outputs «gas and
fault alarms »• 2 programmable 1/0 inputs• charger input• Trickle charge in EX areas• Safety perimeter
• RS485 or radio communication outputs ; (new developments).

« 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 !
