For decades, the humble smoke alarm has been a source of both safety and frustration. We have all been there: you open the oven to check on dinner, or a hot shower releases a cloud of steam, and suddenly the house is filled with the ear-piercing shriek of a false alarm.
While annoying, these false triggers have a dangerous side effect: complacency. When an alarm cries “wolf” too often, people start to ignore it, or worse, take the batteries out to silence it.
At SecureLink, we believe safety should never be annoying. That is why we are introducing a new standard in residential and commercial safety: the Ajax FireProtect 2 RB (Heat/Smoke). This isn’t just a smoke detector; it is a compact computer dedicated to analyzing the air quality of your home, distinguishing real threats from burnt toast.
The Science of Detection: HazeFlow 2 & Dual-Spectrum Sensors
The core innovation of the FireProtect 2 lies in how it “sees” the world. Traditional alarms use a simple optical sensor that triggers when anything blocks the light. The Ajax FireProtect 2 RB uses a revolutionary dual-spectrum optical sensor combined with the HazeFlow 2 software algorithm.
Instead of just detecting particles, it analyzes them using two distinct light wavelengths:
- Blue LED: Detects small, volatile particles typical of smoke from burning materials.
- Infrared (IR) LED: Detects larger particles, such as water vapor and steam.
By comparing the data from these two spectrums, the sensor can instantly recognize the specific “signature” of smoke. This means you can install the FireProtect 2 near a bathroom or a kitchen without fear. It knows that steam is harmless, but smoke is a threat.
Zero Maintenance: Dustproof and Insect-Proof
A common and often overlooked cause of fire alarm failure (or false alarms) is contamination. Over time, dust settles inside the detection chamber, or small insects crawl inside, disrupting the sensor.
Ajax has engineered a solution that requires zero maintenance. The smoke chamber in the FireProtect 2 is completely sealed and features a unique circulation mechanism. It allows air and smoke to enter freely but is physically impenetrable to dust and insects. This ensures that the sensor remains as accurate on day 2,000 as it was on day 1, without you ever needing to vacuum the ceiling.
Rapid Heat Detection: When There Is No Smoke
Not all fires start with a cloud of smoke. Electrical fires, for example, can smolder inside walls, or certain chemical fires can burn cleanly but intensely. To combat this, the FireProtect 2 acts as a hybrid sensor.
It is equipped with two Class A1R thermistors located outside the main enclosure to eliminate detection latency. These sensors monitor the room temperature in real-time and look for two specific danger signs:
- Rapid Rise: If the temperature spikes by 10°C or more within one minute, the alarm triggers instantly—even if there is absolutely no smoke.
- Fixed Threshold: If the ambient temperature exceeds 64°C, the alarm sounds immediately.
This dual-threat detection ensures that whether it is a slow-burning couch or a flash electrical fire, the system catches it early.
The Interconnected Safety Net
In a large two-story home, a sprawling warehouse, or an office complex, hearing an alarm is just as important as the alarm triggering. If a fire starts in the basement laundry room, would you hear the siren from the master bedroom on the second floor with the door closed?
The Ajax FireProtect 2 solves this with Interconnected Alarms. Using a proprietary radio protocol, all fire detectors in your system act as a single organism.
If one detector senses a threat, it sends a signal to the Hub, which activates every siren in the building within 20 seconds. This synchronous alarm is loud enough to wake the deepest sleeper, ensuring everyone has valuable extra minutes to evacuate safely.
Why Choose the “RB” (Replaceable Battery) Model?
In regions where power stability can be an issue, relying on hardwired systems without backup can be risky. The FireProtect 2 RB is designed for autonomy.
This model is powered by two CR123A batteries. Unlike standard 9V batteries that need changing every year, the energy-efficient engineering of the Ajax system allows these batteries to provide up to 7 years of operation.
This means that even during prolonged power cuts or electrical maintenance, your fire safety system remains fully active and vigilant.
Upgrade to Smart Protection with SecureLink
Old-school fire alarms are passive; the Ajax FireProtect 2 is proactive. It doesn’t just make noise; it sends rich notifications to your smartphone, telling you exactly which room is in danger and what triggered the alarm (smoke or heat).
