An extension of the wireless signal is only necessary if the detectors indicate that they only receive one signal bar from the AJAX Hub. This tells them that the range is then insufficient to guarantee correct operation permanently.
The standard range of the AJAX Hub is 2000 meters in open field, but this distance becomes shorter if the Hub has to transmit through thick walls and concrete surfaces.
It can therefore happen that in a very large home or at companies where the detectors are sometimes mounted hundreds of meters from the Hub, the wireless signal is insufficient. Then the solution is simple: use an AJAX ReX to amplify the signal.
ReX is the radio signal range extender that extends the range of all AJAX security systems and manages communication with the Hub. The intelligent radio signal range extender enables users to place AJAX devices at a significant distance from the Hub for the protection of multi-storey offices, freestanding buildings and even production facilities. By connecting 5 ReXs to the security system, the range is extended to 35 km².
AJAX ReX mounting
The AJAX ReX puts you in a location where the wireless signal from the Hub still has sufficient reception and of course in the direction where the detectors are positioned. The above diagram clearly shows how, in a large company, the ReX ensures that an excellent Jeweller signal is present throughout the entire complex.
Mounting is very easy and can be done with 4 supplied screws. The AJAX ReX only needs power, no other wired connections.
The Hub connects to the detectors closest to the Hub, while the AJAX ReX connects to the detectors closest to the ReX.
Even if, for whatever reason, the Hub stops working, the operation of all detectors connected to the ReX continues.
ReX integrates the devices into an autonomous group within the system. The extender takes full control of the situation if the connection to the Hub is interrupted for any reason. If one of its detectors emits an alarm signal, ReX can activate the siren to draw attention to the incident and deter the intruder.
35 Square kilometres of wireless range
By using AJAX ReX it is possible to create a total wireless range of no less than 35 square kilometers. This range cannot be achieved with any other brand of security system, and certainly not wirelessly as AJAX can.
The standard Hub can connect one AJAX ReX wirelessly, and the Hub Plus and Hub 2 can connect up to 5 AJAX ReX. If you need to secure a large company, choose the AJAX Hub Plus or Hub 2 as the central control system.
When AJAX ReX is necessary
Whether an AJAX ReX is necessary is difficult to estimate in advance because it can depend on many factors. Of course, we can give some examples of when we would install a ReX, and when we would not. After all, a ReX is only necessary if the detector at the installed location only displays one or no signal reception bar in the AJAX application.
99.5% of the users do not need an AJAX ReX.
Choose a Rex if the property or company:
– is more than 2500 square meters and consists of many concrete floors.
– You want to place detectors outside the house that are positioned more than 50 meters away from the house.
The above distances are based on our experience. Since every situation is different, it is possible that at your location the distances are much further or less. Each house has different factors that can interfere or positively influence the wireless signal. We know that thick concrete walls and floors obviously reduce the distances.
If you’re not sure if you need a signal amplifier, just try it first without one.
The AJAX system is smart enough to let you know immediately in the AJAX application if a detector at a certain location reports a signal loss. If you don’t receive any messages in the AJAX App after installation, then everything is fine. If you do receive a report of a lost Jeweller signal from one or more detectors, you can still place an AJAX ReX in between. It can be as simple as that.
When no ReX is needed
If you live in a normal sized house or detached house / villa, and you only want to secure the house and the surrounding garden, no AJAX Rex is required for plots with an area of 50 by 50 meters, and the wireless signal emitted by the AJAX Hub will be more than sufficient.
