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.

Definitely worth the price
Size: 6.5, Color: Black/Black
Absolutely love these boots! I originally bought them to wear in NYC in December & they did not disappoint. They were comfortable, cute, durable and worked well in the slush/snow. The traction on the bottom is also nice! They kept me warm with wool socks. I wear them almost daily now. Perfect for everyday. easy to wear with variety of outfits. Good every day shoe.

Snagged a deal
Size: 7, Color: Redwood/Gum 10
I waited and waited to get these boots! I knew I was chancing it, but they went on sale, and I snagged them! I am a size 7, and they fit nicely with socks. a little loose, barefooted, but what psycho wears boots without socks? They are comfortable and really well-made.

Cute, comfortable waterproof boots (a little snug to put on)
Size: 7, Color: Velvet Tan/Gum 2
These are really cute Chelsea-style boots and feel very comfortable once they’re on. The waterproof material is great for wet weather and the sole feels sturdy with good traction. They look stylish enough to wear casually but still feel practical for rainy days. The only downside is they can be a little difficult to put on at first because the opening is somewhat snug, but once they’re on they fit well and feel supportive. Overall they’re a great waterproof boot and I’ve enjoyed wearing them.

Surprisingly great for my wide feet and high instep!
Size: 10.5, Color: Velvet Tan/Gum 2
So thrilled I took a chance on these. Finding boots is impossible for me. I have wide feet, a super high instep, a bunion on one foot, and I wear a hard to find size (10.5). I ordered the 10.5 and 11 in these expecting I might need to size up for width (if I could even get them on). It was a struggle getting the 10.5s on the first time, and once I did they were somewhat uncomfortable on the top of my left foot. But I read that they would relax so decided to give it a go because I need waterproof boots for an upcoming trip and the 11s felt too long. After two days of light wear, they are already breaking in and I have no more discomfort. Getting them on is already easier and they are plenty wide enough and very comfortable to walk in. These are true to size. Super happy and worth a day of mild discomfort to break them in!

Comfortable, sturdy, waterproof
Size: 9.5, Color: Black/Black
Loce, love, love these boots. Have walked ten miles with no foot pain around NYC. They go with everything and and are so comfortable. As they are waterproof/resistant, they get a little warm in high temps, but perfect three-season boots.
