Product information

Description

Ajax REX 807537BL1 is a wireless range extender designed to increase the radio coverage of Ajax smart home security systems. In black finish, ReX expands the protected area by repeating signals between the hub and connected devices, enabling placement of detectors, sirens and other equipment at greater distances — for example in multi-storey offices, detached garages or large production facilities. A single ReX doubles the signal range; using up to five ReX units can expand coverage up to 35 km².

Advantages

ReX delivers alarm notifications in 0.3 seconds and connects to the system in about two minutes. It operates on the same OS Malevich platform as Ajax hubs, performs critical tasks on a powerful ARM processor, and synchronizes data with the hub using a reliable protocol. ReX can assume control of connected detectors if the hub is unavailable, activate sirens locally, and continue operating on internal battery power for up to 35 hours. The device features encrypted communication, jamming detection and tamper protection.

Suitable for

  • Expanding coverage in large homes and multi-storey apartments
  • Securing commercial premises, offices and production sites
  • Extending signal to outbuildings such as garages and workshops
  • Increasing resilience of existing Ajax security systems

Key specifications

  • Device type: wireless radio range extender (indoor)
  • Compatibility: works with Hub and Hub Plus running OS Malevich 2.7.1 or later
  • Alarm signal delivery time: 0.3 seconds
  • Maximum connected devices: depends on hub model (Hub Plus + ReX up to 149 devices; Hub 2 Plus + ReX up to 199 devices)
  • Signal range: up to 1,800 m (single ReX); up to 35 km² with up to 5 ReX units
  • Power: mains 110–240 V; Li‑Ion backup battery 2 Ah (up to 35 hours offline)
  • Operating temperature: -10°C to +40°C; humidity up to 75%
  • Anti-sabotage: jamming detection, tamper protection, encrypted communication
  • Dimensions and weight: 163 × 163 × 36 mm; 330 g
  • Color: black; warranty: 24 months (batteries excluded)

How to use

To add ReX to an Ajax system, scan the QR code with the Ajax app, assign a name and power on the device. Select which detectors will operate via the range extender in the application settings. Mounting is performed without disassembling the unit: attach ReX to the SmartBracket mounting panel and secure it. Use the mobile app to configure, test radio signal strength and confirm correct placement.

Usage recommendations

Place ReX centrally relative to the devices it will serve and avoid large metal obstacles between the hub, ReX and detectors. For large sites, plan placement of multiple ReX units to ensure overlapping coverage and follow the recommended hub and ReX device limits for maximum connected devices. Regularly update firmware via the app to receive stability and security improvements.
