Wireless alarm center for professional installations, both residential and commercial. Communication is done via Ethernet and/or GPRS. The supervised bidirectional link of the detectors and accessories is carried out by radio frequency following its own protocol, Jeweler, in the 868 MHz band, obtaining Grade 2 certification. The wireless link achieves high reliability thanks to its advanced Jeweler protocol with high-speed encryption. AES security. The exclusive instantaneous and intelligent supervision system detects the inhibition of the signal, identifying a certain inactivity time and, in turn, reduces maintenance costs since it considerably extends the life of the detector batteries without compromising security. The wireless signal is capable of covering distances of up to 2 km in open space. It also includes functions to facilitate installation, such as intelligent support (Smart-Bracket) or the simple linking of detectors to the alarm system. It allows up to 100 wireless zones that can be grouped into rooms with independent configurations for arming, partial arming, entry, exit and 24 hours. It has an AC 110-250 V power input. The panel has a rechargeable backup battery with a duration of up to 24 hours. Possibility of integration into the web platform by QR code identification for remote configuration. Ethernet communication is its main advantage for remote access, both for the user and the installer, since it allows connection to the Ajax web application and the Ajax Security Systems application for iOS and Android. Through these applications it is possible to manage users/accounts or configure the system, adding different rooms, devices and modifying their configuration. The use of the cloud supports dynamic IP without the need to open ports. The Ajax user will enjoy multiple advantages, since they will be able to receive reliable and instant notifications both in the web application and in the mobile application.
