Patented smoke chamber technology

Encouraged by world standards and best practices, reaches an entirely new level of technology in residential fire safety with FireProtect 2. A unique smoke chamber that is dustproof and impenetrable for insects, a dual-spectrum optical sensor, and a proprietary HazeFlow 2 software algorithm guarantee the speed and accuracy of fire detection — ultimate safety with no stress about false alarms.


Only real threats considered

In-depth research on materials combustion resulted in HazeFlow 2 — a smoke detection algorithm. The algorithm contemporaneously analyses and compares data from the dual-spectrum optical sensor to a specified pattern to define smoke from vapour or steam. The detector instantly raises the alarm when pattern dynamics indicate a real case of fire.


Even when it's fire without smoke

FireProtect 2 is equipped with two class A1R thermistors to detect smokeless fire threats. They give a significant advantage in detecting a rapid temperature rise when synthetic materials burn, or a fire starts from smoldering. Thermistors are located outside the enclosure to eliminate life-saving detection delays. So FireProtect 2 is ready to detect a fire as fast as possible, even if it starts imperceptibly.


Always informed, everywhere

For residential fire alarm systems, informing people about fire danger is the priority. FireProtect 2 is equipped with a powerful 85 dB siren to eliminate the risk of missing an alarm. The detector uses impossible-to-ignore tones with different patterns to indicate an alarm or event, so it’s easy to recognize the type of threat and react accordingly.

Smoke detection

Sensitive element

double-spectrum optical sensor

Recognizes smoke by the size of particles in the air.

Protection from false alarms

Does not react to water vapour.

Patented smoke chamber

Protects the smoke sensor from dust, dirt, and insects.

Dangerous temperature detection

Sensitive element

according to the requirements for Class A1R heat detectors

Requirements of EN 54-5 and BS 5446-2 standards.

High temperature alarm

at temperatures above 64°C

Temperature spike alarm

when the temperature rises more than 10°C in 1 minute or less

Carbon monoxide (CO) detection

Sensitive element

chemical CO sensor

Alarm if accumulated dose of CO is exceeded

more than 50 ppm (0.005%) — no more than in 90 minutes
more than 100 ppm (0.01%) — no more than in 40 minutes
more than 300 ppm (0.03%) — no more than in 3 minutes

CO concentration of 400 ppm (0.04%) within 3 hours can be life-threatening. The detector stops notifying about the dangerous level of carbon monoxide when the concentration drops to 50 ppm (0.005%) within one minute.

Sensor life

10 years

After 10 years of operation, the detector must be replaced with a new one.

Additional features

In-built siren

volume 85 dB at a distance of 3 meters

Sound notification of alarms. Active until the reason for triggering is eliminated or until the user disables notification.

Interconnected Fire Detectors Alarms

All fire detectors in the system turn on built-in sirens if at least one of the detectors registers an alarm. An interconnected fire alarm is activated during one “hub — detector” polling interval but no more than 20 seconds later.

LED indication

green is a power indication

A LED indicator on the device enclosure lights up once every 56 seconds. The indication meets the requirements of EN 50291.

yellow is an indication of malfunctions

A LED indicator on the device enclosure lights up when malfunctions are detected. For example, in the case of discharged batteries, contamination of the smoke chamber, or end of the service life.

red is an indication of fire alarms

A LED indicator on the device enclosure lights up when the detector registers a fire alarm.

Button on the front panel of the detector

In normal mode, when pressed, it starts the smoke chamber test. In the event of an alarm or malfunction, the pressing turns off the detector sound notification.


The device is designed only for indoor installation. SmartBracket mounting panel allows adjusting the position of the detector after installation.

Anti-sabotage protection

Tampering alarm

Alerts of attempts to detach the detector from the surface or remove the mounting panel.

Detection of communication failure

within 15 minutes

The time to detect communication loss depends on the settings for the number of undelivered data packages (specified in the Jeweller or Jeweller/Fibra settings). The polling interval is fixed at 300 seconds.
