  1. Jessica Miller –

    Ideally, you never want to hear a fire alarm, but knowing this Ajax detector is watching over my house is comforting. The installation was a piece of cake using the app, and the white design is very discreet. Apsardze24.lv handled the order perfectly with quick dispatch. Highly recommended!

What warranty terms apply if I purchase this detector from your store?

Unlike international marketplaces, Apsardze24.lv offers a full **2-Year Warranty** for both private and business clients. Our service center is located in **Riga**, ensuring quick local support for warranty claims.

How does the dual-spectrum sensor prevent false alarms from cooking steam?

The dual-spectrum optical sensor uses both blue and infrared LEDs to distinguish between volatile smoke particles and water steam. This technology significantly reduces false triggers in kitchens or bathrooms compared to single-spectrum sensors.

What is the difference between the RB and SB versions of this fire detector?

The RB (Replaceable Battery) model allows you to change the CR123A batteries after their projected 7-year lifespan. The SB (Sealed Battery) version contains non-replaceable batteries intended to last 10 years, after which the entire unit must be replaced.

Does the Ajax FireProtect 2 RB (119921) work as a standalone device without a Hub?

The detector can operate autonomously to sound its built-in 85 dB siren if smoke or high heat is detected. However, an Ajax Hub is required to receive smartphone notifications and to activate interconnected alarms with other sirens.

Is this the official EU version compatible with the Ajax app?

Yes, this is the official European version fully compatible with the Ajax Security System app on iOS and Android. You can view real-time sensor status, battery levels, and receive instant alerts.

What is the wireless range of the model 119921 for large properties?

This device utilizes Jeweller radio technology to communicate up to 1,700 meters in an open space. This extended range ensures stable connectivity in large homes or commercial spaces without the need for signal repeaters.

Can I configure this detector to trigger all other fire alarms in the building?

Yes, when paired with a Hub, you can enable the 'Interconnected Fire Detectors Alarm' feature. This causes all connected Ajax fire detectors to sound their sirens within 20 seconds if one unit detects a threat.
