Communication

• Jeweller communication technology

Proprietary radio technology for transmitting commands, alarms, and events.

• Main features:
  • Two-way communication.
  • Advanced anti-sabotage protection.
  • Block encryption with a dynamic key.
  • Instant notifications.
  • Remote control and configuration via 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

• Maximum effective radiated power (ERP): up to 20 mW
• Radio signal modulation: GFSK
• Radio signal range: up to 2000 m

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

• Encrypted communication
  • All stored and transmitted data is protected by block encryption with a dynamic key.

• Frequency hopping
  To prevent radio interference and jamming.

Connection of wired devices

• Number of zones: 18 connection zones

Multiple devices can be connected to one zone. The number of connected devices depends on their power consumption.

• Connection type: NC, NO, EOL

for MultiTransmitter Jeweller with firmware version prior to 2.13:

• NC, NO, EOL, 2EOL, 3EOL

The 2EOL and 3EOL connection types are only available for MultiTransmitter Jeweller with firmware version 2.13.0 or later. The integration module must be added to a compatible hub running OS Malevich 2.13 or higher. If Hub (4G) Jeweller is used, the hub must be updated to OS Malevich 2.28 or higher.

• EOL resistance: from 1 kΩ to 7.5 kΩ in 100 Ω increments

for MultiTransmitter Jeweller with firmware version prior to 2.13. The EOL resistance is automatically detected in the Ajax PRO app.

• from 1 kΩ to 15 kΩ per resistor, with a total resistance of up to 30 kΩ

MultiTransmitter Jeweller with firmware version 2.13 and later. The resistance is measured automatically for each EOL resistor in the Ajax PRO apps.

• Cable length: up to 400 m

When using a signal cable with a copper-clad aluminum conductor with a cross-section of 0.22 mm².

• Operating mode: impulse, bistable
• Event types: 15 event types for wired devices
  • Tamper alarm
  • Intrusion
  • Fire
  • Emergency
  • Panic button
  • Gas alarm
  • Malfunction
  • Flood
  • Glass break
  • High temperature
  • Low temperature
  • Masking
  • Duress code (disarming)
  • Vibration (seismic sensor)
  • Custom

Configurable by PRO users or users with administrator rights in the Ajax app.

Anti-sabotage protection

• Tamper protection

Two tamper buttons to detect the opening of the MultiTransmitter Jeweller enclosure and alert if it is removed from the wall.

• Anti-spoofing protection
  • Device authentication

• Connection loss detection
  • within 36 seconds

Between a hub or a radio signal range extender and MultiTransmitter Jeweller. The detection time depends on the Jeweller or Jeweller/Fibra settings.

• Instant detection of cable break, short circuit, and malfunction
  • when using the EOL/2EOL/3EOL connection type

Depending on the connection type.

Power supply

• Power supply for MultiTransmitter Jeweller
  • 100 to 240 V~, 50/60 Hz
• Backup power for MultiTransmitter Jeweller
  12 V⎓, up to 7 Ah capacity, up to 30 hours of battery life when fully charged

Backup battery is not included.

• Power supply for connected devices
  • 10.5–15 V⎓, up to 1 A (max. total power consumption)

Two power supply lines from MultiTransmitter Jeweller for other devices. Separate power supply line for fire detectors.

Enclosure
