  1. Jessica Turner –

    I upgraded my home security with the FireProtect 2, and I’m impressed. The sealed 10-year battery is a game changer—no more chirping at 3 AM! Setup through the app was a piece of cake. Excellent service from the seller as well. It feels great to be fully protected against fire and CO.

How does the Carbon Monoxide (CO) detection work?

The device contains a chemical sensor that detects carbon monoxide, an odorless and invisible gas. It triggers an alarm if CO concentration reaches dangerous levels, such as 50 ppm within 90 minutes or instantly at very high concentrations.

What is the wireless range of the FireProtect 2 SB?

The detector uses the secure Jeweller radio protocol to communicate with the Hub at a distance of up to 1,700 meters in an open space. In a typical building, this easily covers multiple floors.

If one detector triggers an alarm, do other Ajax detectors sound as well?

Yes, if the 'Interconnected Fire Detectors Alarm' feature is enabled in the Ajax app. When the FireProtect 2 SB detects a threat, it signals the Hub to activate the sirens of all other connected fire detectors in the system.

Can I replace the batteries in the Ajax FireProtect 2 SB (49557)?

No, this specific 'SB' (Sealed Battery) model is powered by non-replaceable lithium batteries designed to operate for 10 years. After the battery life expires, the entire unit must be replaced to ensure sensor accuracy and compliance with safety standards.

Is this the official EU version compatible with current updates?

Yes, this is the official EU region device. It is fully compatible with the Ajax Security System app and supports over-the-air firmware updates when connected to a Hub.

Does the Ajax FireProtect 2 SB work without an Ajax Hub?

The detector can function autonomously to sound its built-in 85 dB siren if smoke, heat, or CO is detected. However, to receive smartphone notifications and manage settings via the app, it must be connected to an Ajax Hub.

Will cooking steam or humidity trigger false alarms on this device?

No, this model features a dual-spectrum optical sensor that effectively distinguishes between real smoke and water steam. This smart filtering technology minimizes false alarms typically caused by cooking vapors or bathroom humidity.

What warranty coverage is provided for this fire detector?

Apsardze24.lv offers a full 2-Year Warranty for this product, covering both private and business clients. Warranty claims and technical support are handled locally through our service center in Riga.
