Review: Seco-Larm Electromagnetic Lock....... It Works!! - I purchase this lock as a secure lock for a hidden door walk in closet where i choose to hide my valuables. I chose magnetic lock for the low profile look (no obvious sign to see like a knob or keyhole the will defeat the purpose of being a "hidden door"), Locking power, and no moving parts so its quiet and no parts to lubricate or break down. My setup is quite simple the lock, an old a/c adapter from my sirus radio, and a Christmas light remote to turn it on or off. I also plan on plugging the a/c adapter to my old UPS so that the lock would remain secure for at least 3 hours in a power failure. Now for my Pros and Cons Pros: Relative easy to install. All you need is a good drill and you can get this up in no time Holding Power. My door would give way first before I could separate the plates, it really is held in there. Quiet Operation. You can engage and disengage the lock without anybody noticing you did. Cons: I did say relatively easy to install but you still need basic skills as installing this you do need basic electrical and wood working skills. You need to properly align the base plate with the magnet for it to hold tight, any misalignment of the plates will result in less than satisfactory result. The unit would run warm (which is actually good in cold weather to prevent lock from freezing up) and would consume around 5W of electricity to operate All in all a great buy for me and if in your application you think this kind of lock is best for you its money well spent. Review: but something like this should work https - This is a review for the 1200 lbs lock. So I bought this lock a week ago, when it got here, it took me about 8 hours to install (I had no experience what-so-ever with this before so I had to run back and forth to the store to get cable and drill bits). With it I bought a power supply of 12V 500mA. I was lucky that the power supply was the exact match that the instruction booklet specifies. You must buy the power supply, it does not come with it. This is the one I bought https://www.desertcart.com/gp/product/B000VRL632/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 (I just saved you the trouble of it (: you're welcome). I also bought this exit button to open it from the inside https://www.desertcart.com/gp/product/B0051BUGCA/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 . This exit button has a green LED that requires12V to light up (it did not came with it) The lock did came with the mounting bracket that was compatible with my door, but you might need to buy one that is compatible with yours. (Just buy it as is, if you find out it isn't compatible then buy the bracket separately. They usually go by the name of "Z Bracket for magnetic locking mechanism". The reason I bought this lock was because I own a gym, and I want to provide my members with a 24 hr access. I do want to mention that you also need to buy a device that will unlock the magnetic lock (besides that exit button). My member management software came with one so i did not have to buy one,but something like this should work https://www.desertcart.com/Docooler-Entry-Access-Control-System/dp/B00LQ7SGXO/ref=pd_sim_sbs_421_27?ie=UTF8&psc=1&refRID=182KQWAMTKBQE517YT90 . First, I would like to say that (with proper installation, if i may say so myself) the lock hold VERY WELL. I'm using 12V at 500mA and OI really can't pry it open. I tried using force, tools, and other means to pry it open only to fail to forcibly open it again and again. The quality is a lot better than many of the other locks that I seen online prior to this one, and for the force that it holds it was really a good deal (in my opinion ofcourse). The seller specifies that you should use a 1A power supply, but the specifications say 500mA, and that worked just fine with me (less electricity cost too). You also have to determine if this lock is what you need. Remember, if there is a power outage, the lock will open! If this is a security risk for your needs thenI would recommend getting another type of lock, or installing an emergency powers supply for when that happens (something like a battery). Overall I personally am very happy with this lock. I added some photos of the installation and the specifications for the power supply. I hope this helps!

Holding Force - Image 1](https://m.media-amazon.com/images/I/51epsmTcb8L.jpg) ## Questions & Answers **Q: how do you wire this electromagnetic lock** A: All you need is a 12VDC or 24VDC power supply (depends on the model you buy), I would recommend at least capable of putting out 1A. As long as the power is supplied, the lock will be held closed. You can put in a switch between the power supply and the lock to control on/off. If you want to install a pin keypad or keyless remote entry then you will have to buy a separate kit for that... But essentially the same concept, they will provide constant 12VDC to the lock holding it closed until you enter a key releasing the lock for few seconds. **Q: It any other door electromanegnetic powerfull than 1,200 lbs** A: The standard holding forses are 600 lbs and 1200 lbs. 1200 lbs is a very strong holding forse and feel it is more than adequate to hold in any situation. **Q: Is this suitable for an outdoor installation like a garden gate?** A: Yes, but the incoming wires has to be covered and you will have to seal the edges on the unit. I think this unit is a little too powerful for a garden gate. **Q: What size wire should be used to connect the power supply to the lock?** A: 18 gauge wire is fine unless it is a long run than go to 16 gauge stranded is best ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seco-Larm Electromagnetic Lock.......

This is a good bare feature price; you can pay extra for their other model with extra features like LED status light, access buttons and panels, power supply and feedback on door open/close status. Just remember that this model does not come with a power supply. This lock is great for its flexibility; it will close easily, regardless of the magnet's alignments- so it works perfectly with uneven doors and frames. Lastly, the outer casing has excellent hard tamperproof metal security as well as moisture/rust proofing. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.id/products/3578688-seco-larm-e-941sa-1200-electromagnetic-lock-with-1200-lb](https://www.desertcart.id/products/3578688-seco-larm-e-941sa-1200-electromagnetic-lock-with-1200-lb) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-05-11*
