^{Sebelum Beli Dan Pasang, Yuk Cari Tahu Dulu Macam-Macam Detektor Kebakaran Alarm kebakaran merupakan suatu perangkat yang paling banyak diandalkan untuk mencegah kerugian besar ketika kebakaran terjadi. Apapun macam detektor kebakaran dalam alarm, pada dasarnya alat ini berfungsi sebagai penanda yang siap memberi tahu Anda secara cepat dan tepat ketika ada api penyulut kebakaran. Keberadaan fire alarm memungkinkan Anda untuk melakukan evakuasi dan langkah pemadaman secara cepat dan bebas panik. Fire alarm yang diproduksi secara massal dan dijual di pasaran memiliki berbagai jenis detektor. Hal ini sangat wajar, karena penyebab kebakaran tidak bisa digeneralisasi, melainkan berbeda-beda bergantung situasi dan fungsi suatu area. Jadi, ketika Anda ingin berbelanja alarm kebakaran, Anda harus terlebih dahulu mengenal karakteristik tempat yang akan dipasang fire alarm, serta piawai pula memilih detektor kebakaran yang sesuai. Berikut ini informasi mengenai macam-macam detektor kebakaran dan penjelasannya secara rinci. Rate Of Rise Heat Detector Ini merupakan alat pendeteksi kebakaran yang didesain peka terhadap kenaikan panas di suatu area yang dipasang fire alarm. Prinsip kerja detektor menggunakan saklar bi-metal yang akan merespons ketika mendeteksi panas dalam ukuran tertentu. Ukuran tertentu yang dimaksud yakni mencapai titik 55 hingga 63 derajat Celsius. Alarm akan segera berbunyi ketika mendeteksi panas yang beranjak naik secara cepat maupun perlahan, sehingga Anda bisa segera menyadari adanya bahaya kebakaran sebelum api menyebar ke ruangan atau gedung lain. Adapun jangkauan area deteksi untuk detektor kebakaran yang satu ini yakni mencapai 50 meter dan ketinggian 4 meter. Jika alarm dipasang di langit-langit yang lebih tinggi, maka jangkauan area deteksi akan berkurang menjadi 30 meter. Anda dianjurkan untuk tidak memasang detektor ini di ketinggian lebih dari 8 meter agar kinerjanya terjaga akurat. Kebanyakan orang menggunakan alarm rate of rise heat detector untuk dipasang di kantor, kamar hotel, ruang arsip, gudang pabrik, rumah sakit dan area strategis lainnya. Detektor kebakaran jenis ini paling banyak dipakai oleh masyarakat dan pelaku usaha karena sejumlah pertimbangan. Di antara alasan Rate of Rise Heat Detector paling banyak dicari adalah aplikasinya yang luas dan dinamis serta harganya yang relatif murah. Detektor jenis ini juga bisa langsung dipasang di panel alarm rumah karena tidak membutuhkan tegangan. Fix Temperature Ini merupakan macam detektor kebakaran yang sebenarnya termasuk ke dalam kategori heat detector. Adapun yang membedakannya adalah kemampuan fix temperature yang bisa mendeteksi bahaya kebakaran akibat kenaikan panas dalam suatu area secara drastis. Adapun area efektif detektor yakni seluas 30 meter dan ketinggiannya empat meter. Maka dari itu, penempatan Fix Temperature biasanya di area yang terbiasa memiliki suhu panas seperti dapur, basement, bengkel las, gudang dan ruangan beratap asbes. Area-area yang barusan disebutkan pada dasarnya sudah bersuhu panas. Jadi, dengan menggunakan fix temperature, risiko falset akan tercegah karena alat masih mendeteksi aman ketika suhu panas berlangsung stabil. Smoke Detector Selanjutnya ada smoke detector yang dirancang peka terhadap keberadaan asap dengan jumlah tertentu. Alat ini mampu melakukan deteksi awal terhadap asap yang masuk, lalu akan menangkap tanda bahaya apabila keberadaan asap di suatu area melewati batas maksimal. Dalam proses kerjanya, smoke detector memiliki area proteksi seluas 150 meter dan dengan ketinggian 4 meter. Smoke detector juga membutuhkan tegangan dari panel yang sesuai karena berisi rangkaian elektronik yang spesifik. Panel yang dimaksud bisa berupa panel fire maupun panel alarm biasa. Smoke detector juga dibagi menjadi beberapa jenis, di antaranya yakni Ionisation Smoke Detector dan Photoelectric Type Smoke Detector. Untuk yang disebut pertama, detektor bekerja berdasarkan jumlah partikel asap yang ditangkap radioaktif. Sementara jenis smoke detector yang kedua, Photoelectric Type Smoke Detector, memanfaatkan bias cahaya LED. Alat akan bekerja dan mengirimkan tanda bahaya kebakaran ketika asap masuk ke ruang detektor dengan kepadatan tertentu. Flame Detector Flame detector atau detektor api didesain sensitif terhadap radiasi sinar ultraviolet yang dihasilkan oleh api yang menyala. Detektor jenis ini dinilai cukup akurat, karena ia hanya terpengaruh oleh api dan ledakan yang jelas_jelas merupakan potensi bahaya kebakaran. Jadi, alat ini tidak akan terpengaruh oleh nyala dan panas lampu ruangan, infra merah, dan sumber cahaya lain yang bukan api. Ketika Anda memilih macam detektor kebakaran jenis ini, perhatikanlah soal penempatan agar fungsinya menjadi optimal. Pasanglah alarm kebakaran flame detector di tempat yang bebas atau tidak terlalu dekat dengan lampu halogen, lampu mercury, atau lampu untuk sterilisasi. Untuk mencegah falset, jangan pula memasangnya di area yang rentan percikan api, misalnya ruang las. Gas Detector Macam detektor kebakaran yang terakhir adalah gas detector. Di mana, fungsi utama detektor ini yakni mendeteksi kebocoran gas yang berpotensi kebakaran untuk jenis gas Liquefied Petroleum Gas LPG dan Liquefied Natural Gas LNG. Ketika Anda ingin menggunakannya untuk mendeteksi potensi bahaya pada LPG, silakan menempatkan detektornya dengan posisi menghadap ke atas, serta ditempatkan di area bawah, dengan jarak sekitar 30 cm dari lantai. Tujuannya agar ketika terjadi kebocoran gas bisa segera terdeteksi. Demikianlah informasi seputar macam detektor yang ada pada fire alarm. Setelah mengetahuinya, kami berharap Anda bisa memilih produk fire alarm secara tepat dan sesuai dengan kebutuhan. Jika masih ada hal yang ingin ditanyakan seputar fire alarm, jangan ragu untuk mengajukan pertanyaan kepada kami melalui admin website, atau membuka ruang diskusi di kolom komentar.

When you see a person sweeping a metal detector in your local park, it's only natural to fantasize about finding a buried treasure in your own backyard. Metal detecting is a well-established hobby with thousands of fans, who use their detectors in all kinds of ways, from combing beaches for lost jewelry to competing in local contests between expert detectorists. Yes, they exist! Even if you don’t plan on using it to explore, a good detector can even help you find a lost item or cherished memento lost in the dunes. But let’s hope you never need to.Before you purchase your first metal detector, it's important to have an idea of how you want to use it. From beachcombers to gold prospectors, there are a lot of different types of detecting to consider, not to mention the many kinds of ground you can scan. Once you know what you’re looking for, we can help you find the best metal detector for your next OverallMinelab Vanquish 440Read moreBest ValueGarrett Ace ApexRead moreBest for BeginnersNokta Simplex+Read moreSimple And PortableGarrett Ace 300Read moreMinelab Equinox 800Read moreThe Experts Steven T. Wright As a longtime nerd and technology writer, I've written about computers and tech products for almost a decade at publications like PC Gamer, Ars Technica, and Polygon. To assemble this guide, I relied on the expertise of two seasoned metal detecting experts who have decades of experience in the field. I also relied on insights and recommendations from online guides, as well as reviews from both experts and Ross started metal detecting in 1971. In 2012, while living on the beachfront in Seal Beach, CA, he joined The Ring Finders, a directory of metal detecting specialists that help people find lost items for a small fee. He's helped hundreds of people find their lost keepsakes and sentimental items. Finding lost items for people has become a passion for him and a way to use his years of metal detecting Lubbert has been an avid metal detector since 1980 and joined The Ring Finders directory in 2010. He was named “Ring Finder of The Year” in 2011. In his decade-plus of service, he's returned over 200 items to their owners, with a total estimated value exceeding $900,000. He is an active officeholder in Denver's Eureka Treasure Hunters Club and the co-host of American Digger Magazine's Relic Roundup, a weekly metal detecting To Consider When Choosing A Metal DetectorBefore we talk about how to pick a metal detector, we should quickly explain how they work. Consumer metal detectors have a round head known as the "search coil," which is the part that actually does the detecting. There are two parts to the coil, the transmitter coil and the receiver coil. When you turn the detector on, it sends an electrical current into the transmitter coil, creating an electromagnetic field that reaches down into the ground when the coil is held perpendicular to it. The magnetic field causes metal objects underground to give off their own magnetic fields, which the detector coil can read. The detector can determine how far underground an object is based on the relative strength of the opposing magnetic detectors can also determine what kind of metal they're detecting within limits by measuring an object’s phase shift, or the time it takes for the object to react when the transmitter coil changes its current. This technique, called “discrimination,” can help you tell the difference between treasure and trash That said, our experts are quick to note that discrimination is an imperfect technology, and it's best not to always take it at its first thing to look at before buying a metal detector is where you plan to use it, as some detectors are better equipped to scan specific types of terrain. For example, if you live near the coast and plan to sweep your local beach, you may want a different model than someone looking under hard soil in local are three major types of metal detectors, in ascending order of cost Very low frequency VLF, multi-frequency, and pulse induction PI.Very low frequency detectors operate on one frequency at a time. According to Lubbert and Ross, they’re made for entry-level hobbyists looking for coins and jewelry, but won’t work well for gold prospecting or scanning saltwater beaches. Most VLF models allow users to switch between a number of frequencies, but rarely allow you to input a specific one detectors detect over a range of frequencies at the same time, making them a good choice for serious hobbyists, especially those who plan to search in wet conditions. They’re generally more expensive than their VLF counterparts, but they can be used in mineralized soil and saltwater beaches. They’re also usually larger than VLF machines, and not as induction detectors are professional-grade equipment used for salvaging and serious gold prospecting. They use a different kind of technology than VLF and multi-frequency detectors, sending out short bursts of powerful current to scan deep under the they can detect hard-to-reach metals, pulse induction detectors have more trouble telling one type of metal from another, forcing you to dig up every significant piece of metal they find. Gold prospectors and serious divers use pulse induction detectors on saltwater beaches and other mineralized ground, but they’re not for most hobbyists. They’re heavy and have a high learning curve. Plus, they cost thousands of We Selected The Best Metal DetectorsMost of the metal detectors in this guide were recommended by our experts based on the factors above. We also sifted through dozens of product listings, reviews from consumers and experts, as well as enthusiast guides from UnderCoil, and more. We looked to highlight a wide range of detectors to suit a variety of needs, from beginners looking to dip their toe in, to hobbyists looking for an upgrade. No matter where you stand, we have you OverallMinelab Vanquish 440Best OverallMinelab Vanquish 440ProsSimple, yet full-featuredMulti-frequency supportLightweightConsNot as water-resistant as more expensive modelsKey SpecsTypeMulti-frequencyCoil Size10 lbWaterproofYes, up to ftThe Minelab Vanquish 440 offers a tremendous amount of functionality for less than the cost of some less powerful VLF detectors. For just under $300, it's a little more expensive than true entry-level models, but it offers a lot of features that enthusiasts look for. Its four find modes support all different types of terrain, from turf to fields, and its multi-frequency technology allows it to search saltwater beaches without any problems. You can set and save your own frequency settings to figure out what works best for your area and search style. Perhaps best of all, it weighs only lbs.

The flagship of Garrett’s Ace detector line, the Apex has a large backlit display and six detection modes, including specific finder settings for coins, US coins, jewelry, relics, and a custom most interesting option is its "iron audio" feature, which helps you identify complex iron objects that you probably don't want to dig up, such as bottle caps. Likewise, the notch discrimination feature lets you filter out certain frequencies if you're trying to avoid metal Garett Ace Apex is priced for knowledgeable enthusiasts, so it isn’t exactly cheap, but you’re getting a very powerful detector for a very appealing price.

It's a wildly popular starter model with a lot of features that you want in a beginner-friendly metal detector. It features four search modes, a backlit screen, and notch discrimination, allowing it to distinguish a coin from a bottle cap, for instance. It's also waterproof up to 10 feet, which is better than most models in its price range, so it’s a good choice for wading. The retractable shaft makes it easier to transport, it is a VLF model, the Simplex+ is not going to work well on a saltwater beach or in mineralized soil.

It has a large screen, a water resistant coil, and five search modes suitable for a variety of terrain, including dry beaches. It also has better pinpointing and iron identification modes than several other models in its price its relatively low price, it shouldn’t come as a surprise that the Ace 300 lacks some of the finer flourishes found on premium detectors, such as a backlit screen and specific water resistance. Its default coil is also only 10 inches, though you can upgrade it with a larger one. Garrett is a name that detectorists trust, so it's an easy recommendation to give to new hobbyists who aren't too concerned about fancy bells and Equinox 800Minelab Equinox 800ProsLightweightSupports all terrains and detecting typesGood display backlightConsSome portability concernsNot as good at gold prospecting as PI machinesKey SpecsTypeMulti-frequencyCoil Size11 lbWaterproofYes, up to 10 ftDescribed by Ross as the best option for the “dedicated enthusiast,” the Minelab Equinox 800 is a multi-frequency detector capable of doing almost anything you'd want, especially at the beach. Its coil can pick up metal on wet sand and even while wading in saltwater, and its four detection modes can find coins, jewelry, “relics,” and even gold nuggets on the most mineralized soil. Though it has fewer modes than some similar detectors, such as the Vanquish 440, a machine like the Equinox will likely find more metal and at a greater uses the Minelab Equinox 800 for many of his jobs, and he's used it while wading up to his neck in the ocean. Though it is lighter than most detectors, the fixed shaft length may make it hard to carry around, and reviewers say the length may make it hard to use for anyone shorter than 5-feet-6-inches. At more than double the price of our beginner and best overall picks, the Equinox 800 is definitely made for a discerning detector fan with a lot of For Underwater Minelab Excalibur IIBest For Underwater Minelab Excalibur IIProsSuitable for divingCan be used on all terrain, including wet beachesKey SpecsTypeMulti-frequencyCoil Size10 lbWaterproofYes, up to 200 ftThe Minelab Excalibur II is designed for hardcore enthusiasts who want to take a metal detector on their snorkel or more likely scuba dive. Equipped with BBS multifrequency technology designed specifically to detect in saltwater or mineralized conditions, the Excalibur 2 detects in 17 frequencies simultaneously. For comparison, the above Vanquish 440 scans on just five.It’s also a powerful piece of gear on land, though it’s much heavier than most multi-frequency detectors, so it may not be the best choice out of the water. It also lacks the large screen you'll find on other models Instead, you control it with rotary dials that let you control its two detection Excalibur II was created and optimized for a very specific scenario. If you’re treasure diving, this is one of the best options on the market.

Lubbert says that kids might enjoy playing with these toys, but they're just that – toys. If you’d like your child to actually get a taste for the hobby, we recommend paying a few dollars more for the Nokta Mini Hoard, which is the rare metal detector for kids that works Mini Hoard has three tones for different kinds of metal and a display that indicates a good or bad find. It's small enough for children as young as four to use without much trouble.

Lubbert says the Deus II has the edge over several other detectors he loves in terms of speed and versatility. It features a whopping 12 different detection programs for every conceivable terrain, and has an additional 12 open slots for custom scans. It also has collapsible stems, so it's more portable than many other detectors in its also comes with a wireless remote control that lets you adjust settings on the fly, and you can fit it with a special plug to bring it underwater. The Deus II is rated to dive to 66 feet, making it suitable for some underwater expeditions, wet beaches, and mineralized soil. It’s the ultimate upgrade for a veteran, despite its sky-high price With Our ExpertsLubbert and Ross say that newcomers to the hobby often underestimate the importance of proper target retrieval equipment. By "target retrieval equipment," we mean the gear you need to dig up whatever you find. You should not plan to bring a large shovel when using your metal detector in public places, as local authorities and property owners generally frown on people digging large holes in parks and yards. It’s also illegal in some jurisdictions, even when metal detecting isn't.As with other aspects of metal detecting, you bring retrieval gear based on the terrain and soil you plan to scan. For example, sand scoops work well on dry sand, whereas you may need a trowel or Lesche digging tool – also known as a “soil knife” – for hard may also want to buy a pinpointer, which is a handheld metal detector with a tiny search coil that's designed to help you narrow down the exact location of the you should learn proper digging techniques, such as the "flap" method, where you make three sides of a square with a sharp edge and lift the resulting flap with the edge of your tool. When you’re done digging, make sure to use a sod plug to fill in the resulting T. Wright is a freelance writer based in Miami, FL.
