  1. Daniel Foster –

    I’m really pleased with this Ajax FireProtect 2. The black design is subtle, and the setup was incredibly straightforward via the app. It’s great having smoke, heat, and CO detection in one unit with such long battery life. Service from apsardze24.lv was top-notch, with very quick delivery.

    Daniel Foster –

Is the Ajax FireProtect 2 RB compatible with all Ajax Hubs?

This device requires a Hub running OS Malevich 2.15 or higher. It is compatible with Hub Plus, Hub 2 (2G/4G), Hub 2 Plus, and Hub Hybrid, but it is not compatible with the first-generation Hub or ocBridge Plus.

What batteries does the FireProtect 2 RB model use and how long do they last?

The "RB" in the model name stands for Replaceable Battery; it is powered by 2 × CR123A batteries which are included. The device operates for up to 7 years on these batteries before they need replacement.

How does the CO (Carbon Monoxide) sensor work on this device?

The detector includes a chemical sensor that detects dangerous levels of carbon monoxide automatically. It triggers an alarm if the CO concentration reaches 50 ppm within 90 minutes, 100 ppm within 40 minutes, or 300 ppm instantly.

Can I mute the siren without using the mobile app?

Yes, the entire front panel of the detector acts as a mechanical button. In the event of an alarm, you can press the front panel with your hand or a mop handle to mute the siren locally.

What warranty does Apsardze24.lv provide for this detector?

We provide a comprehensive 2-Year Warranty on the Ajax FireProtect 2 RB. As Apsardze24.lv is based in Riga, our local service center handles all warranty claims and technical checks quickly for clients in Latvia, Estonia, and Lithuania.

Does this detector require an Ajax Hub to function?

The device can operate as a standalone smoke and CO detector with its built-in siren, but an Ajax Hub is required for smartphone notifications and system integration. Without a Hub, you will not receive alerts on your phone or be able to configure settings via the Ajax app.

Does the smoke chamber on the FireProtect 2 require regular cleaning?

No, this model features a patented dust-proof smoke chamber that is impenetrable to insects and dust. Unlike older generations, it does not require regular disassembly or cleaning to maintain its detection accuracy.

Does the Ajax FireProtect 2 RB (52253) trigger false alarms from cooking steam?

No, this detector utilizes a dual-spectrum optical sensor that specifically distinguishes between volatile steam and actual smoke. This makes it suitable for installation near kitchens, as the software algorithm minimizes false alarms caused by cooking vapors.

What should I do if the LED indicator blinks yellow continuously?

A yellow LED typically indicates a malfunction or a low battery level, which will be detailed in the Ajax app device status. If the issue persists after checking the app diagnostics, please contact our technical support at [email protected].

Will other Ajax fire detectors sound if this one triggers an alarm?

Yes, if you have an Ajax Hub, you can enable the "Interconnected Fire Detectors Alarm" feature. This ensures that if one detector identifies fire or CO, all fire detectors in the system will activate their sirens within 20 seconds.
