Accuracy through steam, dust, and time
FireProtect 2 AC is a mains-powered detector designed for residential fire safety. The unique smoke chamber does not require regular cleaning, and sophisticated software minimizes false alarms. The dual-spectrum sensor instantly distinguishes smoke from steam, and two thermistors quickly react to the synthetic materials’ burning. Everything meets the latest fire safety standards. Thought-out design, improved mounting panel with WAGO 221 connectors, and in-app settings make the installation process nice and easy, giving an ultimate experience for PRO.

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 AC. 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 AC 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 AC is ready to detect a fire as fast as possible, even if it starts imperceptibly.

- 10°C increase in temperature within a minute
- Exceeding +64°C
Stable performance for a decade
The detector is powered by 110–240 V~ mains and has a sealed battery to serve as a backup. Even in a power outage, the detector keeps operating smoothly. Designed for the quick and reliable fire detection over its 10-year lifespan.
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.

Enhanced wireless interconnection
All FireProtect 2 AC detectors can synchronously notify about the fire alarm in two ways: primary and fallback . In case of danger, the initiating detector sends a fire alarm to the hub. The hub initiates the primary interconnect: all fire detectors will activate the built-in sirens in 20 seconds — three times faster than the fire standard requires. All information is immediately available in Ajax apps: initiating detector’s location, alarm type, and exact time. If there is no connection with the hub, the initiating detector activates the fallback interconnection bydirectly sending the alarm to other fire detectors. It takes only 1 minute to raise an alarm.
20 seconds to activate up to 200 fire detectors
Less than a minute to activate up to 50 fire detectors
Unleash the Ajax power
The Ajax smart and complex ecosystem brings new standards to the fire safety industry. FireProtect 2 AC 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.
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.

Jeweller
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.
Up to 1,700 m of radio communication with a hub
Encrypted two-way radio communication
Notifications about jamming and connection loss
Scaled and comprehensive
For complex radio signal conditions like large houses with thick walls or warehouses with several buildings, there is the ReX range extender. It boosts the range of all Ajax devices and manages their communication with the hub via Jeweller. And ReX 2 assures stable communication even through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering underground parking, basements, and metal hangars.

Sleek wiring with CableTrunk accessory
CableTrunk is a solution for safe and aesthetic joining between the Ajax mains-powered FireProtect 2 AC and cable trunking. Run power wires to the side of the detector while preserving the neat look of the ceiling.
Effortless installation and maintenance
FireProtect 2 AC is ready to operate straight out of the box. It takes only 90 seconds to install the detector with no need to disassemble the enclosure. The upgraded SmartBracket mounting panel now has the lever-actuated WAGO 221 connectors familiar to every industry expert. An installer can wire the power supply without a screwdriver, secure the detector on ceilings, and level it at 90° angles after mounting.
The device is paired with the hub by scanning the QR code in the Ajax apps. And it can always be reconfigured remotely without site visits. A self-test system automatically diagnoses sensors and reports their state to the hub. Testing can also be run manually anytime in the app or by pressing the detector front panel.
