Second generation repeater for Ajax ReX 2 security system
The connecting device above the physical layer of the network is called a repeater. The device is used to connect two identical network lines. Its main task is to extend the transmission distance of the network by forwarding or retransmitting signals. A repeater is a device of the physical layer of the OSI model of network equipment that restores signals. The repeater is a simple connection device that is designed to increase the network distance in a local communication environment. It works in the OSI physical layer. The repeater can regenerate and amplify the line signal.
What is the repeater used for in signaling
A security repeater connects network lines to exchange physical signals between two network nodes. The repeater is the simplest network equipment for connection, often completing the function of the physical layer. It is responsible for bit data transmission on the physical layer of two nodes and replicates the signal, configures and amplifies it to extend the length of the network. If the signal is lost, the line power will decrease, and when it relaxes as much as possible, the signal is distorted and this will lead to an error. The repeater is designed to solve problems of this kind. It completes the connection of the physical circuit and increases the signal strength. As a rule, both ends of the alarm repeater are connected to the same carrier, but some repeaters may be responsible for the operation of several devices.
Second Generation Wireless Signal Repeater for Ajax ReX 2 Security System
The Ajax ReX 2 wireless repeater increases the range of radio communication of security devices with a control panel by half (works with Ajax Hub 2, Hub 2 Plus centers). The Ajax repeater is also equipped with a light indicator of operability, an Ethernet port for connecting a backup communication channel with the central and tamper via cable. ReX 2 is an intermediate link for receiving and transmitting signals between the security devices connected to it and the center. The wireless repeater interacts with the control panel and alarm devices via the two-way Jeweller protocol at an operating frequency of 868-868.6 MHz. The range of communication with the center reaches 1700 m and 1700 m to the detector (depends on the type). This principle of operation allows you to connect a wireless sensor to the alarm control panel at a distance of up to 3400 m. Broadcast signals are protected from data forgery by encryption. With pings at intervals from 12 to 300 seconds, stable communication of all devices is monitored. The alarm signal arrives at the alarm center in less than 0.3 seconds. Remote testing and configuration of the Ajax ReX 2 wireless repeater is also available via the free Ajax mobile app. Connection to the security system occurs after scanning the QR code on the device body. All notifications are sent to users' mobile phones via push notifications, SMS messages or calls. Thanks to the tamper on the body of the Ajax ReX 2 wireless repeater, when trying to dismantle or damage an attacker's device, the user of the security system will receive a corresponding message. The power supply to the repeater comes from AC 110-240V, 50/60 Hz or 12V with 12V PSU for Hub 2/Hub 2 Plus/ReX 2. The backup power source is a 2 Ah Li-Ion battery that supports the autonomous operation of the wireless repeater for up to 38 hours. The alarm case is made of durable black or white plastic in a minimalistic design.
The main purpose of the wireless repeater for the Ajax – ReX 2 security system
The ReX 2 wireless signal repeater is used to increase the transmission distance of the radio signal between the alarm devices and the control panel. By connecting 5 ReX 2 wireless repeaters to Ajax signaling, you can extend the coverage of the radio network to a distance of up to 35 km2. The ReX 2 wireless repeater can also work as an additional intelligent panel: the device is able to combine sensors into an autonomous group and, if communication with the alarm center is lost, it will take control, activating sirens and other automation scenarios and informing about events.
The main features of the Ajax ReX 2 alarm repeater
The repeater works with Ajax MotionCam and Ajax MotionCam Outdoor detectors that support photoverification of alarms, which is the main difference between Ajax ReX 2 and its predecessor Ajax ReX. This significantly expands the capabilities of the device thanks to the Wings radio protocol for transmitting photoverifications of alarms and connecting motion sensors with a built-in camera. Ajax security systems can be connected to the monitoring console of a specialized security organization for a higher level of control. The use of the ReX 2 wireless repeater in extraneous security systems is not provided.
