## Long description

Ajax REX Black is a wireless range extender designed to expand the coverage of Ajax alarm and security networks. The device receives and retransmits wireless signals between Ajax hubs and devices, increasing communication range and strengthening connectivity in larger homes, multi-room apartments, office premises and buildings with structural obstacles. Its compact black housing and low-profile dimensions allow flexible placement while maintaining a discreet appearance within a protected environment.
Advantages
The range extender improves signal stability and reduces the number of blind spots by relaying communications between sensors, detectors and the central hub. Installation is wireless, so the device can be positioned where signal strength needs improvement without additional cabling. Its compact dimensions and neutral black finish make it suitable for mounting on walls or placing on shelves. The extender is intended to enhance overall system reliability and maintain uninterrupted alarm reporting across extended areas.
Suitable for
Large houses and multi-level residences where direct hub coverage is insufficient
Multi-room apartments with signal dead zones caused by interior walls
Commercial premises and small offices requiring extended wireless coverage
Buildings with thick walls or metal structures that attenuate radio signals
Key specifications
Wireless signal reception and retransmission to extend network range
Compact dimensions: 163 × 163 × 36 mm for unobtrusive placement
Black enclosure suitable for discreet indoor installation
Designed for use with Ajax alarm and security systems
How to use
Place the Ajax REX Black in a location between the hub and the devices that experience weak reception, ensuring it remains within the operating range of both. Follow the Ajax system setup procedure to add the extender to the hub via the mobile app or control interface; the device will begin receiving and retransmitting signals once paired. Positioning tests using signal indicators or the system diagnostics help identify optimal placement to achieve consistent connectivity throughout the protected area.
Usage recommendations
Install the extender at a midpoint where it can reliably communicate with both the hub and the furthest devices; avoid metal enclosures and large obstacles directly adjacent to the unit. Verify placement using the system’s signal strength tools and relocate the extender if necessary to eliminate dead zones. Regularly check device status in the Ajax app to ensure the extender is functioning and receiving power.
