Instant, Powerful, and Smart Indoor Alert

Deter intruders and alert everyone in the vicinity with the AJAX HomeSiren Jeweller, a powerful wireless indoor siren designed for the modern smart security system. Ready to work straight out of the box, this sleek black siren installs in minutes and provides an immediate and robust layer of audible security. When any detector in your Ajax system is triggered, the HomeSiren activates with a loud, adjustable alarm, ensuring that any threat is met with an unmistakable warning.

Customizable to Your Needs

Take full control of your alert system. Through the intuitive Ajax mobile app, you can easily adjust the siren's volume from 81 to 105 dB and set the alarm duration from 3 seconds up to 3 minutes. This flexibility allows you to tailor the siren's response to suit the size of your space and your specific security preferences. The device also features a built-in LED to indicate the system's armed or disarmed status and includes a connector for an optional external LED, which can be placed outside to visibly monitor your security status.

Uncompromising Wireless Reliability

The HomeSiren operates on AJAX's proprietary Jeweller radio technology, ensuring a secure and reliable connection to the hub up to 2,000 meters away in open space. This advanced two-way communication is encrypted and protected against jamming and forgery, providing a tamper-resistant link you can trust. The system constantly polls the device, with communication loss detected in as little as 36 seconds. With a remarkable battery life of up to 5 years from its pre-installed CR123A batteries, you can count on long-term, maintenance-free protection.

Advanced Features for Complete Peace of Mind

Beyond a simple alarm, the HomeSiren is a smart component of your security ecosystem. It features a 'Chime' function that can produce a special sound to notify you when opening detectors are triggered while the system is disarmed. A built-in tamper alarm will instantly notify you of any attempt to detach the siren from its mount or remove the enclosure. Easy to install with the SmartBracket mount and simple to connect to your hub via a QR code, the HomeSiren Jeweller is the essential indoor audible alert for your AJAX security system.

Great sheets
Color: White, Size: Twin
These sheets were priced well, I purchased 2 sets for bunk beds for our grandchildren. The sheets are soft and easy to make up the beds ( as easy as bunks can be ). Nice deep pockets too wrinkle resistant too.

Finally we BOTH can sleep comfy!
Color: 08 - Black, Size: Queen
So for years my boyfriend has always liked “jersey sheets” or “tee shirt” sheets or sheets made of flannel. He says he doesn’t like the feeling of cold “silky” feeling sheets as he’s always cold. I’m opposite and am always hot, and anytime we stayed in a nice hotel I looked forward to being able to sleep on cooler, taught, soft sheets for a couple of nights. I was able to deal with our old sheets but the issue we both hated was after awhile any sheet we got would get pilling. We even splurged and got a $60 flannel sheet which did the same thing forcing me to shave off these little annoying fuzz balls that make it feels like there is thousands of crumbs on the sheets. I also would wash our bedding once a week because the Jersey sheets seemed to “grow” as we move around in bed making it so the sheet was not taught and super annoying to lay on. The day I would wash them they would be comfortable but ultimately by the end of the week they would be almost hanging off our mattress. I ordered these sheets on a whim and got them the same day and immediately just threw out the jersey sheet and put this on (I didn’t even wash it, I know it’s gross but I was desperate for a comfy nights sleep and they came around 8pm) when I put them on I realized how soft and comfortable they felt. I also liked how the pillow cases are larger than most pillow cases that I have had in the past. We’ve been using these sheets for about a week and I love how I don’t wake up with my pillow popping out of the case anymore. The sheets have loosed ever so slightly since a week of sleeping but still are really taught and comfortable. They are cooler than flannel or fabric sheets and are initially cold when you first lay on them but I wouldn’t consider them “cooling” but they keep me from feeing extremely hot. They are way better than I ever would have expected for the price. I look forward to laying on them at the end of each day, even my boyfriend laid in bed the day I got them and said “wow I didn’t think I would like sheets like this, these are so soft!” And fell asleep immediately. We ended up ordering a second set in grey and the color is pretty. I still have yet to wash them, I usually use 2 tide pods when washing the bedding but I might get some fabric softener (as I hear it helps with pilling) to prevent the possibility of having that happen to these sheets in the future. I am hoping they hold up well after the wash and longer use. If they start to pill after wash, I will come back and update my review. Until then, I would highly recommend these sheets for the quality and the price point that they are offered at. Honestly, at this point even if they pill months from now I probably wouldn’t even be upset as long as they stay the same price I would just buy another set as they are just that comfortable and soft. UPDATE: So it has been about 3 months since I have purchase and used these sheets. They are still as soft as the day I first put them on. I’ve been washing them bi-weekly along with my comforter and pillowcases. I wash them with warm water using a combination of tide pods and added Downy fabric softener. They say to hang dry them in the description but I have been putting them in the dryer on medium and have been taking them out after around 20-25 minutes, they seem to dry extremely quickly. They have yet to have absolutely any pilling and also have not shrunk or stretched. Also I have a cat that is very active and also sleeps with me who enjoys kneading on my bed and I haven’t even noticed any signs of wear what so ever to the eye or to the feel. I highly recommend these sheets. I still have yet to even open the second set I purchased!

Happy With Our Purchase
Color: 07 - Charcoal, Size: King, Color: 07 - Charcoal, Size: King
When we opened the package the sheets were soft. We wash everything before we use it, so in these went. The sheets held nicely through the washing machine, the edges stayed sewn up and the sheets are still fluffy. The sheets fit nicely on our bed and have a nice cooling effect in this 80-degree weather. We think these sheets were a quality purchase that was affordable.

Honest Review
Color: 25 - Burgundy, Size: Queen
Very good product, I would highly recommend it. It is soft and keeps you cool throughout the night. I am someone who burns hot all day and night so these sheets have been a great purchase so far as I can tell. I got the red ones and they are very nice and pleasing to the eye. The quality of the sheets is high and not to bad for the price considering other products. It’s not very elastic so make sure you purchase the right size. You get 2 pillow cases and 2 sheets. The sheets seem pretty durable as well which is nice.
