FireProtect 2 RB (CO) Jeweller

Wireless CO detector with replaceable batteries

FireProtect 2 RB (CO) Jeweller


Jeweller communication technology

Proprietary wireless technology for transmission of alarms and events.
  • Two-way communication.
  • Protection against device spoofing.
  • Block encryption featuring a floating key.
  • Instant notifications.
  • Remote configuration via the Ajax apps.

Radio frequency bands

866.0 – 866.5 MHz
868.0 – 868.6 MHz
868.7 – 869.2 MHz
905.0 – 926.5 MHz
915.85 – 926.5 MHz
921.0 – 922.0 MHz
Depends on the region of sale.

Maximum effective radiated power (ERP)

up to 20 mW
Automatic power control to reduce power consumption and radio interference.

Radio signal modulation


Radio communication range

up to 5,500 ft
Between the detector and a hub (or radio signal range extender) in an open space.

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.

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 9 ft
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, if the battery is low.
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, runs the detector test when pressed. 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.

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.
