Ajax FireProtect 2 AC (Heat) Jeweller in White

FAQs

What does the FireProtect 2 AC (Heat) Jeweller detect?

The FireProtect 2 AC (Heat) Jeweller is a heat detector that monitors temperature changes. It detects two types of fire conditions: rapid temperature rise (when temperature increases by 10°C within one minute) and static temperature threshold exceeding (when temperature exceeds +64°C). The detector uses two built-in class A1R thermistors located outside the enclosure to eliminate detection delays.

How is the detector powered?

The detector is powered by 110-240 V~ mains power (50/60 Hz) and includes a sealed backup battery (CR 2/3 AA). Even during power outages, the detector continues to operate using the backup battery, ensuring continuous fire protection throughout its 10-year lifespan. The Battery Life Optimization feature must be enabled to ensure maximum backup battery lifetime.

What is the coverage area of one detector?

The coverage area of one FireProtect 2 AC (Heat) detector is 50 to 60 m², depending on the type of premises. The detector should be installed in every room, preferably in the center of the ceiling at a distance of 30 cm from light fixtures, chandeliers, or other decorative objects.

Can the detector work without an Ajax hub?

Yes, the FireProtect 2 detector can operate autonomously without connecting to an Ajax hub. In autonomous mode, the detector notifies of fire using only its built-in siren and LED indication. However, users won’t receive notifications on Ajax apps, Ajax Translator, or PRO Desktop when operating autonomously.

What is the Interconnected Fire Detectors Alarm feature?

This feature allows all FireProtect 2 AC detectors in the system to synchronously notify about fire alarms through two methods: primary (via Ajax hub) and fallback (detector-to-detector). When a fire is detected, the hub activates the primary interconnection in 20 seconds, while the initiating detector simultaneously activates the fallback interconnection. Even if connection with the hub is lost, the interconnected fire alarm takes only a minute to activate.

How do I test the detector?

You can test the detector in two ways: by pressing the Test/Mute button on the center of the front panel for 1.5 seconds, or through the Ajax app by going to the detector settings and clicking on the Self-test field. Wait at least 3 minutes after turning on the detector before running a test. During the test, the red LED flashes 5 times and the siren activates simultaneously.

What do the different LED colors indicate?

The detector has three LED indicators: Green LED indicates power status (constantly on when connected to external power, flashes once per minute on backup battery), Yellow LED indicates malfunctions or low battery (flashes twice every minute for malfunctions, once per minute for low battery), and Red LED indicates alarms (flashes continuously during fire alarm, every 4 seconds when muted, 2 times for alarm restoration).

How do I mute an alarm?

To mute an alarm, press the Test/Mute button on the center of the front panel. This will mute the detector alarm or Interconnected Alarm of all fire detectors in the system for 10 minutes. You can also mute alarms through the Ajax app. If the source of the alarm is still present after the 10-minute muting period, the alarm will resume.

What is the communication range of the detector?

The detector communicates with the Ajax hub via the secure Jeweller radio protocol with a range of up to 1,700 m without obstacles. If you need to extend the range, you can use a radio signal range extender, which can double the communication distance.

How long does the backup battery last?

The sealed backup battery (CR 2/3 AA) is designed to last for the detector’s 10-year lifespan when the Battery Life Optimization feature is enabled. After a low battery notification, the detector can operate for another month under normal conditions. The detector must be replaced with a new one after the backup battery is discharged.

Where should I NOT install the detector?

Do not install the detector: outdoors, in places with fast air circulation (near fans, vents, open windows), opposite objects with rapidly changing temperature (heaters), in corners of rooms, in bathrooms or areas with rapid temperature changes, near lighting fixtures that may interfere with air circulation, on surfaces warmer or colder than the rest of the room, or in high/inconvenient places where access to the Test/Mute button is difficult.

What maintenance does the detector require?

The detector has a self-test system and requires minimal maintenance. Periodically clean the detector enclosure of dust, cobwebs, and other contaminants using a soft dry cloth. Do not use substances containing alcohol, acetone, gasoline, or other active solvents. It’s recommended to run periodic self-tests (monthly) to familiarize people with the alarm sound and LED indication.

What should I do when the detector reaches end of life?

The service life of the detector is 10 years. After this period, the sensitivity of the sensors decreases. Replace the detector with a new one to ensure uninterrupted fire protection. The detector must also be replaced after the backup battery is completely discharged.

Which Ajax hubs are compatible with this detector?

The detector is compatible with Ajax hubs that have firmware OS Malevich 2.18 and later. The Hub (4G) Jeweller must have OS Malevich 2.28 or later to support this detector. The fallback interconnection functionality requires hubs with OS Malevich 2.19 and higher.
