SPECIFICATIONS:

Communication

Jeweller communication technology

Proprietary wireless communication technology to transmit commands, alarms, and events.

Key features:

• Two-way communication.

• Advanced sabotage protection.

• Block encryption featuring a dynamic key.

• Instant notifications.

• Remote configuration in the Ajax apps.

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 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 1,200 m

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 1 cm from the detector, and the big magnet — up to 2 cm. Attach the magnet on the right side of the detector.

Protection against reed switch chattering

The detector ignores vibrations lasting up to 0.15 s.

Input to connect an additional detector

Wired detector with the normally closed (NC) contact type.

How to connect a third-party wired detector

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.
