PRODUCT DETAILS
The Ajax FireProtect 2 AC is a next-gen 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.
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.
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.

| Interconnected fire detectors
alarms |
via primary interconnection If one of the fire detectors in the system detects a threat, it sends an alarm to the hub. Within 20 seconds, the hub initiates an interconnected alarm and sends data to Ajax apps. via fallback interconnection At the same time with notifying the hub, the initiating detector sends an alarm directly to other detectors. All connected detectors activate the buzzer within a minute. It will work even in the worst-case scenario of losing connection with the hub. |
| LED indication |
green is a power indication An LED indicator on the device enclosure lights continuously when powered by an external power source. If the device draws power from the backup battery, the LED indicator lights up once every 56 seconds. This indication complies with the requirements stipulated in EN 14604 and EN 50291 standards. yellow is a malfunction indication An LED indicator on the device enclosure lights up to signal detected malfunctions. This can occur in instances such as battery depletion, smoke chamber contamination, or reaching the end of the service life. red is a fire alarm indication An LED indicator on the device enclosure lights up when the detector registers a fire alarm. |
| Button on the front panel of the
detector |
In normal mode, when pressed, it starts
the smoke chamber test. In the event of an alarm or malfunction,
the pressing turns off the detector sound notification. |
| External power supply |
110–240 V~, 50/60 Hz The phase and neutral cables from the external power supply should be connected to the WAGO terminals on SmartBracket mounting panel. To remove the detector from SmartBracket, there is no need to disconnect the power cables. |
