{"product_id":"ma1f-ma1r-ma2f-ma2h-nema-44x13-alarm-horn","title":"E2S: MA1F \/ MA1R \/ MA2F \/ MA2H","description":"\u003cp\u003eThe MA-series alarm horn sounders (MA1F, MA1R, MA2F, and MA2H) are high-performance audible signaling devices engineered for industrial, fire alarm, and general warning applications in harsh indoor and outdoor environments. All models are housed in a fire-retardant, impact-resistant ABS enclosure rated NEMA Type 4\/4X\/13, ensuring reliable operation in wet, corrosive, and high-contamination locations. The series is designed for durability and ease of installation, featuring stainless steel, ratchet-adjustable mounting brackets, wide input voltage ranges, and high-efficiency Class D amplifier technology that delivers high sound output with low in-rush current and reduced power consumption. Compact mechanical designs and robust construction make the MA-series suitable for demanding industrial, utility, and life-safety signaling systems. \u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eAcoustic performance across the range is optimized to meet varying ambient noise conditions and coverage requirements. The MA1F delivers up to 117dB(A) via a compact flare horn, while the MA1R provides 114dB(A) of omni-directional sound output for uniform area coverage. The MA2F increases output to 123dB(A) using a high-efficiency flare horn, and the MA2H achieves a very high output of 129dB(A) using the E2S 2H super high-output flare horn, engineered for maximum audibility in extreme noise environments. The MA2F and MA2H models incorporate two user-selectable power settings, allowing system designers to balance sound pressure level and current consumption, making the MA-series a flexible solution for scalable industrial and fire signaling applications.\u003c\/p\u003e","brand":"E2S Warning Signals","offers":[{"title":"108dB(A) \/ Flare re-entrant horn","offer_id":41997958119504,"sku":"MA1FDC024CN1A1R","price":664.13,"currency_code":"USD","in_stock":true},{"title":"105dB(A) \/ Omni-directional horn","offer_id":41997958152272,"sku":"MA1RDC024CN1A1R","price":664.13,"currency_code":"USD","in_stock":true},{"title":"114dB(A) \/ Flare re-entrant horn","offer_id":41997958185040,"sku":"MA2FDC024CN1A1R","price":750.8,"currency_code":"USD","in_stock":true},{"title":"120dB(A) \/ High Output Flare re-entrant horn","offer_id":41997958217808,"sku":"MA2HDC024CN1A1R","price":864.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1007\/0346\/files\/E2S-MAseries.png?v=1774273166","url":"https:\/\/www.thesignalsource.com\/products\/ma1f-ma1r-ma2f-ma2h-nema-44x13-alarm-horn","provider":"The Signal Source","version":"1.0","type":"link"}
