Ultimate Fire and Carbon Monoxide Protection for Your Home

The AJAX FireProtect 2 RB is a next-generation wireless detector designed to provide comprehensive safety against fire and carbon monoxide poisoning. This sleek black device is equipped with three advanced sensors—heat, smoke, and carbon monoxide—to ensure the earliest possible detection of any threat. Its patented smoke chamber is designed to be maintenance-free, protecting the dual-spectrum optical sensor from dust, dirt, and insects, which significantly reduces false alarms. The detector can distinguish between smoke and water vapor, making it suitable for installation in various environments, including kitchens.

Advanced Detection Technologies

The FireProtect 2 RB utilizes a dual-spectrum optical sensor to identify smoke by the size of particles in the air, ensuring a swift and accurate response to real fires while ignoring harmless substances like steam. In addition to smoke detection, it features two built-in thermistors that react to rapid temperature increases, triggering an alarm if the temperature exceeds 147°F or rises more than 50°F in a minute or less. The integrated chemical CO sensor provides a crucial layer of protection against the silent threat of carbon monoxide, with a sensor life of 10 years. The detector will sound an alarm if CO concentration exceeds dangerous levels, potentially saving lives.

Seamless Integration and Reliable Performance

This detector operates on AJAX's proprietary Jeweller radio communication technology, ensuring a secure and reliable connection with the hub over a long range. All transmitted data is protected by block encryption with a floating key. In the event of a fire, the interconnected alarm feature will activate the sirens of all fire detectors in the system within 20 seconds. While it can function as a standalone unit with its powerful 85 dB built-in siren, connecting it to an AJAX hub unlocks its full potential, including remote configuration and instant notifications to your smartphone via the Ajax app. The device is powered by replaceable batteries with a life of up to 7 years.

Nice price for a good product
Color: gray
They’re a great fit at a good price I’ve used them before and I put them in before I have my oil change done because otherwise they try to charge you like lots of money for both of those when it takes five minutes max to get them both in your car

IMPRESSED!
Item Package Quantity: 1, Item Package Quantity: 1
I bought this for my Honda civic 2017 lx 1.5 and it is a perfect fit. I didn’t realize how important it is to change it. Let me tell you if you are thinking about buying this, it’s your sign not JUST because of health which is vital and first and foremost but the PRICE! At any oil change or auto shop they will charge no less than 50$ and I’ve seen higher. I will continue to buy this brand. I will update in my next 5,000 miles. 8.00$ or 50$+ and the quality is EXACTLY the same, your choice.

2016 Honda civic ex
Item Package Quantity: 1
Fits perfectly in my 2016 Honda Civic EX. Installation was quick and easy, and the air coming from the vents smells much cleaner now. It seems to trap dust and pollen well and is a good replacement for the OEM filter.

Perfect fit and reasonable price. Easy to replace in my 2019 Honda CR-V. It takes about 10 minutes to replace. Don't let a dealership rip you off.
