Transmitter Jeweller

Jeweller communication technology

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

Key features:

• Two-way communication.
• Advanced anti-sabotage.
• Block encryption featuring a dynamic key.
• Instant notifications.
• Remote control and configuration in 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 radio interference.

Radio signal modulation

GFSK

Radio communication range

up to 5,200 ft

Between the integration module and a hub (or a range extender) in an open space.

Encrypted communication

All stored and transmitted data are protected by block encryption featuring a dynamic key.

Frequency hopping

To prevent radio interference and jamming.

Supported configurations

Transmitter Jeweller has two pairs of terminal inputs for tamper and alarm sensor connection. Alarm and tamper inputs can be used to connect a wired device using the AATT (Alarm Alarm Tamper Tamper) scheme.

Terminals for wired device connection

• “+ –” — 3.3 V⎓ power supply output for connecting a wired device.
• ALARM — inputs for connecting a wired device.
• TAMP — inputs for connecting a tamper of a wired device.

Protection against spoofing

integration module authentication

Accelerometer

alert when the integration module is moved

Tamper alarm terminals

Terminals for connecting to a wired device tamper (if applicable).

Detection of communication loss with integration module

after 36 s

Detection time depends on the Jeweller or Jeweller/Fibra settings.
