PFEER compliant. Up to 105dB(A) \noutput.   Input overload \nprotection. Volume control\nu\t IP66 enclosure   Can be powered \nfrom BA386 \nflashing beacon.   3 year guarantee\u003cbr\u003e\u003cbr\u003eThe BR385 is a third generation \nintrinsically safe field mounting \nsounder which supersedes the \nBA385-IIC and BA385-IIB. The new \nsounder, which produces a loud \naudible warning signal in a hazardous \narea has forty nine different first stage \nalarm sounds selectable by internal \nswitches. Each first stage tone can be \nchanged to a second or a third stage \nalarm sound by an external contact \nwhich may be in the safe or hazardous \narea. Selectable outputs include DIN, \nNFS, PFEER, Australian and \nSingaporean defined warning, alert \nand evacuation tones.\n\u003cbr\u003e\u003cbr\u003eMain application of the BR385 \nsounder is the generation of unique \naudible warnings within a hazardous \narea. The sounder may be powered \nfrom a wide range of Zener barriers or \ngalvanic isolators and may be \ncontrolled by any contact or dc supply \nin the safe area. The BR385 may \nalso be switched in the hazardous \narea by an intrinsically safe relay, or \nany equipment with an intrinsically \nsafe, simple apparatus switch output, \nsuch as a BEKA Intrinsically safe loop \npowered indicator or a serial text \ndisplay.\n\u003cbr\u003e\u003cbr\u003eThe selected first stage tone can be \nchanged to a different second or third \nstage tone by inter-connecting \nsounder terminals using a switch \ncontact, which may be in the safe or \nhazardous area. This enables one \nsounder to announce up to three \ndifferent conditions, for example, \nalarms warning, alarm and automatic \nshut-down.\n\u003cbr\u003e\u003cbr\u003eA crystal controlled oscillator\naccurately defines the frequency and \nrepetition rate of each alarm signal. \nThis ensures that when multiple \nBR385 sounders are activated at the \nsame time the output tones from all \nthe sounders remain synchronised.\u003cbr\u003e\u003cbr\u003e\nATEX, IECEx and FM intrinsic \nsafety certification permits \ninstallation in all gas hazardous zones \nand all gas groups. Input safety \nparameters allow use with a wide \nrange of Zener barriers and galvanic \nisolators, and zero output parameters \nsimplify intrinsic safety system design.\u003cbr\u003e\u003cbr\u003e\nA BA386 LED flashing beacon may \nbe powered from the same Zener \nbarrier or galvanic isolator as the \nsounder. This significantly reduces \ninstallation costs of a combined \nsounder and beacon system and \nincludes an alarm accept function, \nwhile only marginally reducing the \nsound output, but may only be used \nfor ATEX systems. See the BA386 \ndatasheet for full information.\n\u003cbr\u003e\u003cbr\u003eThe robust ABS enclosure which is \nflame-retardant provides IP66 \nprotection and is suitable for external \nmounting. Cable entry is via three \ntapped holes which will accept a \n20mm glands or conduit fittings. A \n20mm knock-out is also provided in \nthe rear of the enclosure.\n\u003cbr\u003e\u003cbr\u003eThe BR385 contains overvoltage \nprotection to prevent damage during \ncommissioning and to allow the \nsounder to be tested in a safe area \nwithout the need for a Zener barrier or galvanic isolator.\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e","brand":"Bartec USA","offers":[{"title":"Default Title","offer_id":48343163666644,"sku":"BR385","price":395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0837\/0451\/2724\/files\/BR385-2.png?v=1785176857","url":"https:\/\/sejqw6-v1.myshopify.com\/products\/br385-audible-sounder-intrinsically-safe","provider":"Reliability Direct Store, LLC","version":"1.0","type":"link"}
