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.

The FireProtect 2 smoke chamber does not require regular cleaning.

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.

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.

Unleash the Ajax power

The Ajax smart and complex ecosystem brings new standards to the fire safety industry. FireProtect 2 is ready to protect your home without an Ajax hub but can do even more when connected to it. Intuitive Ajax apps provide remote setup and all detector information in real-time from anywhere the Internet is available, on a smartphone or PC. With instant notifications, there is no chance of missing a fire alert, and scenarios let you automate fire security to enhance home protection while you’re away. A complete set with stable wireless communication — essential reliability tested over the years by nearly two million users.

Only with Ajax

Full monitoring for the building

The system instantly notifies about alarms with the critical alerts from the Ajax apps. Security companies and users know exactly which device triggered, when and where it happened. The system controls each device state and reports if there is a malfunction or it's time to replace the batteries.

The event log records 500 recent events within the system. The data is explicit with the device, time, and description of the event. It helps reconstruct the actual event and find the causes to obtain comprehensive information for firefighters or an insurance company.

Monitoring with PRO Desktop

With PRO Desktop, building administration staff can observe not only security but Ajax fire detectors for instant reaction to alarms. Device statuses, event log, batteries data — the CMS operator has a complete picture in one intuitive interface, all informative and centralized. The installation engineer can remotely change the settings and provide services in time.

Advanced automation for greater safety

Ajax fire detectors are a part of the Ajax ecosystem and can interact with automation devices and PhOD detectors of the MotionCam lineup through scenarios. In the case of a fire alarm, the WallSwitch relay de-energizes the house, and Relay activates emergency lights. At the same time, MotionCam (PhOD) sends pictures into Ajax apps to identify the cause of the alarm. The result is a reliable combination of security and automation that works as a Swiss watch.

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.

Ajax wireless technology has up to 1,700 meters of radio signal communication range in an open space, making it on average longer than competing solutions from different manufacturers. Automatic power adjustment makes it energy efficient by not using the maximum power of radio transmitters in system devices on a regular basis. It is also more stable, using less noisy radio frequencies. Ajax hubs use radio hopping to protect against radio interference and signal interception. The system automatically changes frequency within a band and notifies the security company and users about the jamming.

Heat and smoke fire detectors

Protect your property from fires with advanced devices that detect the first signs of heat. Heat detectors give you additional peace of mind and can be used in areas where smoke detectors cannot. Heat detectors accurately detect and respond to convicted thermal energy, triggering an alarm to alert nearby occupants. They are designed to complement smoke detectors and are typically installed in areas where smoke detectors are unsuitable, such as kitchens, laundry rooms, or utility closets, where excessive dust or steam can trigger false alarms. Here are the most common types of heat detectors: Fixed temperature heat sensors are the most common type of heat detector found in homes and businesses. They sound an alarm when heat-sensitive alloys inside liquify in response to significant heat in the immediate area. Rate-of-rise thermal detectors signal an alarm when there's a rapid increase in heat, from 12 degrees to 15 degrees Fahrenheit, and utilize heat-sensitive thermocouples to measure temperature accurately. When it comes to smoke detectors, ionization smoke detectors have an electrical current that runs through two metal plates inside the device. They are ideal for detecting fires that spread quickly. Photoelectric smoke detectors go off when the light inside the device is disrupted by smoke, and detect small fires faster than an ionization smoke detector. Make sure your property is equipped with the proper detectors to keep your residents and assets safe. Familiarize yourself with the different types of detectors to ensure the best possible protection for your premises. Using the example of the Ajax combined fire detector, we will explain how such a device works and what its features are.

Heat and smoke detector Ajax FireProtect 2 (Heat/Smoke)

FireProtect 2 (Heat/Smoke) is a wireless smoke and temperature detector designed for instant fire detection. It features a unique smoke chamber that does not require cleaning, a dual-spectrum sensor that distinguishes smoke from steam, and thermistors that quickly react to burning synthetic materials. Its sophisticated software minimizes false alarms, and it meets the most modern fire safety standards. The device operates through steam, dust, and time and has a well-thought-out design, mounting, and in-app settings, which makes installation straightforward and quick. The smoke detection system uses optical sensors with infrared LEDs. The LEDs emit light with different wavelengths, which allows the detector to determine the size of the volatile particles and react only to smoke. The smoke chamber is protected from dust, dirt, and insects, and the optical system is designed so that non-volatile particles or insects cannot be in two beams simultaneously and cause a false alarm. FireProtect 2 (Heat/Smoke) also detects a rapid temperature rise with two built-in thermistors that are located outside the detector for faster threat detection. If the room temperature exceeds 64 °C or increases at more than 10 °C per minute, the detector recognizes this as a rapid temperature rise and raises the alarm. The temperature alarm can trigger even if there is no smoke in the room.

Connectivity: Jeweller communication technology and interconnected fire alarms

The device supports interconnected fire alarms and has an advanced algorithm that activates all fire alarm sirens within 20 seconds. The function is available only when the detectors work with the hub. Wireless alarm fire detectors FireProtect 2 (Heat/Smoke) can be used without connecting to an Ajax hub. In this case, the detector notifies fire alarms with a built-in siren and LED indication but does not send a notification to the user's smartphone, Ajax Translator, or PRO Desktop. The detector regularly checks the status of batteries and built-in sensors, and the hub notifies users and the monitoring station instantly if a malfunction is detected. The detector supports manual testing mode, which allows the installer to test the device at any time and to demonstrate to the customer the light and sound indication of the detector for various types of alarms. Wireless fire detector from Ajax FireProtect 2 (Heat/Smoke) features Jeweller communication technology, a radio protocol for fast and reliable two-way communication between hubs and connected devices. The protocol provides a wireless radio communication range with FireProtect 2 (Heat/Smoke) up to 1700 meters. This communication range allows you to install detectors even on large-scale objects.

Battery options: Replaceable and non-replaceable batteries

Two models of FireProtect 2 (Heat/Smoke) are available — with replaceable and sealed batteries. Detectors with replaceable batteries operate for up to 7 years with pre-installed CR123A batteries. After their discharge, the batteries can be replaced with new ones. The model with non-replaceable batteries works from built-in lithium batteries for at least 10 years. After the batteries are discharged, such a detector should be replaced with a new one. FireProtect 2 (Heat/Smoke) is a next-gen device that is perfect for homeowners, and large-scale facilities. Its accuracy through steam, dust, and time make it a reliable device that ensures the safety of everyone in the building.
