Alarm control panel with on-board keypad capable of managing up to 48 radio peripherals (indoor and outdoor presence detectors, magnetic contacts, wired contacts for roller shutters, self-powered siren and GOLD 869 Series radio controls) and 2 wired devices expandable to 7. The transmission protocol is bidirectional, digital and dual frequency, operating on the frequencies 868.00-868.60 MHz and 869.40-869.65 MHz. The bidirectionality of the latest-generation protocol allows the peripherals to know the system status - Armed/Disarmed - placing them in Stand By mode when the system is not armed, significantly saving battery power. Furthermore, when the system is armed, the peripherals operate without inhibition, ensuring a security status equivalent to a wired system. To save energy, sophisticated software is able to establish the distance between the control panel and each of the peripherals, modulating the output power accordingly. Numerous features, such as FH (Frequency Hopping), TDMA (Time Division Multiple Access), and AES (Advanced Encryption Standard), ensure security and reliability against external attacks. Continuous communication between the control panel and peripherals makes the system immune. The system is capable of detecting jamming-type attacks. The radio communication protocol allows for a transmission range of up to 1.5 km in open air.
