Depends on the sales region.
Maximum effective radiated power (ERP)
up to 20 mW
Automatic power control to reduce power consumption and noise interference.
Radio signal modulation
GFSK
Radio signal range
up to 3,900 ft
Between detector and control panel (or range extender) in an open space.
Encrypted communication
All the data stored and transmitted are protected by block encryption with a dynamic key.
Frequency hopping
Radio communication uses frequency hopping to prevent interception and jamming.
Detection
Sensitive element
1 reed switch
Magnets
small and big one come in the set
The small magnet operates at a distance of up to 0.4″ from the detector, and the big magnet — up to 0.8″.
Protection against reed switch chattering
The detector ignores vibrations lasting up to 0.15 s.

Chime
When the system is disarmed, the siren makes a special sound to notify that the opening detectors are triggered.
Recommendations
Do not install the detector using both magnets at the same time. The detector recognizes only one magnet on one side of the detector.
Attach the magnet to the moving part of the door (window) to the right of the detector. The side to which the magnet should be attached is marked with an arrow on the detector’s enclosure.
The device is designed for indoor use only.
Sabotage protection
Tamper alarm
Notifications on attempts to detach the detector from the surface or remove it from the mounting panel.
Protection against spoofing
device authentication
Communication loss detection
after 36 s
Depends on the Jeweller or Jeweller/Fibra settings.
