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

GFSK

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.

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 147°F

Temperature spike alarm

when the temperature rises more than 50°F in 1 minute or less

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.

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.
