Ajax FireProtect 2 RB Wi-Fi Jeweller White 52252.137.WH1

Ajax FireProtect 2 RB Wi-Fi Jeweller White

Accuracy through steam, dust, and time

FireProtect 2 is a next-gen detector designed for residential fire safety. The unique smoke chamber does not require regular cleaning, the dual-spectrum sensor distinguishes smoke from steam, the thermistor quickly reacts to the synthetic materials burning, and sophisticated software minimizes false alarms. Thought-out design, mounting, and in-app settings make installation straightforward and quick. Everything meets the most modern fire safety standards.

Detection

Patented smoke chamber technology

Encouraged by world standards and best practices, Ajax reaches an entirely new level of technology in residential fire safety with FireProtect 2. A unique smoke chamber that is dustproof and impenetrable for insects, a dual-spectrum optical sensor, and a proprietary HazeFlow 2 software algorithm guarantee the speed and accuracy of fire detection ultimate safety with no stress about false alarms.

Impenetrable for dust and insects

The smoke chamber is designed with zero possibility of contamination that can affect detection. A unique circulation mechanism provides the optical sensor with an unobstructed field to quickly identify products of combustion in the air.

Ignores сooking fumes and water steam

The smoke chamber is hardwired with a dual-spectrum optical sensor that has blue and infrared LEDs with different wavelengths. It uses the most reliable real-time detection method, directly measuring the microparticle concentration in the air. This technology allows FireProtect 2 to determine the size of the volatile particles inside the chamber and respond only to smoke, ignoring vapour and water steam.

Only real threats considered

In-depth research on materials combustion resulted in HazeFlow 2 — a smoke detection algorithm developed by Ajax. The algorithm contemporaneously analyses and compares data from the dual-spectrum optical sensor to a specified pattern to define smoke from vapour or steam. The detector instantly raises the alarm when pattern dynamics indicate a real case of fire.

Protects from invisible danger

Carbon monoxide (CO) is colorless, odorless, and otherwise imperceptible without a carbon monoxide detector, so poisoning can occur unnoticed. Even low concentrations can be enough to have a negative health impact, especially on those with chronic illnesses, pregnant, the elderly, and young children. High-level exposure can cause permanent damage or even death in a very short period of time. FireProtect 2 warns about a dangerous CO concentration at the level of 50 ppm before even the first signs of poisoning occur. A built-in chemical sensor is responsive to low concentrations and can accurately detect the CO level straight up to 10 years.

Even when it's fire without smoke

FireProtect 2 is equipped with two class A1R thermistors to detect smokeless fire threats. They give a significant advantage in detecting a rapid temperature rise when synthetic materials burn, or a fire starts from smoldering. Thermistors are located outside the enclosure to eliminate life-saving detection delays. So FireProtect 2 is ready to detect a fire as fast as possible, even if it starts imperceptibly.

Autonomous operation

Stable performance for a decade

Cutting-edge engineering of hardware and software allowed us to implement advanced capabilities and offer autonomy in the size of the compact smart detector. FireProtect 2 complies with strict residential fire safety standards with long-lasting battery life while featuring constant data exchange with a hub and real-time analysis system to filter false alarms. The detector is available in two versions with different battery options to cover every market need.

Low battery warning

The detector reports low batteries at least 30 days before its full discharge. Installers and users get notifications from their Ajax apps. Also, FireProtect 2 has an LED indicator and audible beeps for a low battery alert.

Always informed, everywhere

For residential fire alarm systems, informing people about fire danger is the priority. FireProtect 2 is equipped with a powerful 85 dB siren to eliminate the risk of missing an alarm. The detector uses impossible-to-ignore tones with different patterns to indicate an alarm or event, so it’s easy to recognize the type of threat and react accordingly.

Wireless interconnection

All FireProtect 2 detectors can synchronously notify about the fire. As soon as one of them detects a threat, it only takes 20 seconds for the sirens of other fire detectors at the facility to activate. If the fire occurs at night, the volume of 85 dB can wake up even a deep sleeper.

Unique wireless technologies

The Ajax system uses two-way secure radio communication based on the Jeweller proprietary protocol. It supports block cipher encryption and device authentication on every session with the hub to prevent sabotage, spoofing, or data theft.
