  1. Sarah Jenkins –

    The black finish looks really sharp on my ceiling; it fits my interior perfectly. Setting it up was a piece of cake since it’s totally wireless. I feel much safer knowing it tracks both smoke and temperature jumps. Fast shipping from apsardze24.lv was a nice bonus!

    Sarah Jenkins –

Do multiple Ajax FireProtect detectors sound simultaneously during a fire?

Yes, if they are connected to an Ajax Hub, you can enable the **Interconnected Fire Alarms** feature. This ensures that if one detector triggers an alarm, all other connected fire detectors in the building will activate their sirens within 20 seconds.

How often do I need to change the batteries in the 38104 model?

The device is highly energy-efficient and comes with pre-installed CR2 batteries that last up to **4 years** under normal use. The app will notify you well in advance when the battery levels are running low.

Does this wireless smoke detector also react to rapid temperature changes?

Yes. Even if there is no smoke, the device triggers an alarm if the room temperature exceeds 60°C or rises by 30°C within 30 minutes. This dual-sensor technology ensures faster detection of various fire types.

What happens if my detector stops working after a year?

We offer a comprehensive **2-Year Warranty** for both business and private clients. Since our service center is located locally in **Riga**, warranty repairs or replacements are handled quickly without the need to ship the unit abroad.

How do I clean the smoke chamber if the 38104 gives a dust alert?

The device performs self-diagnostics and will notify you if dust accumulates in the smoke chamber. You can usually clean it by carefully vacuuming the grill or using compressed air. If the alert persists after cleaning, please contact our technical support at [email protected].

Is the 38104 Ajax FireProtect the official European version?

Absolutely. This is the **Official EU version** of the device, ensuring full compatibility with local networks and no region locking for future firmware updates. Apsardze24.lv is an Authorized Partner, guaranteeing authentic hardware.

Can I use the 38104 Black Ajax FireProtect without a central Hub?

Yes, this detector can operate independently. If it detects smoke or a heat spike, the built-in 85dB siren will sound to alert people inside the building. However, to receive notifications on your phone or use interconnected alarms, you must connect it to an Ajax Hub.

Which mobile app is required to configure the 38104 Black Ajax FireProtect?

You need to download the free **Ajax Security System** app, available for both iOS and Android. The app allows you to scan the QR code on the device for instant connection, adjust sensitivity settings, and monitor the battery status remotely.
