Calculate radio communication range at the facility
Encryption of radio communication
All the data stored and transmitted are protected by block encryption with a floating key.
Radio frequency hopping
To prevent radio interference and jamming.
Sensitive elements
smoke sensor
heat sensor
CO (carbon monoxide) sensor
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 vapor.
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.
Recommendations
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.
Protection against spoofing
device authentication
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.
