Lince Italia 9522 Centrale gold 869 48 zones wl2 row zones e

Alarm control unit with on-board keyboard capable of managing up to 48 radio peripherals (indoor and outdoor presence detectors, magnetic contacts, wire contacts for roller shutters, self-powered siren and GOLD 869 Series radio controls) and 2 rows 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 status of the system - Armed/Disarmed - placing them in Stand By condition with the system not armed with a notable battery saving; furthermore, when the system is switched on, the peripherals operate without inhibition, guaranteeing a safety status equivalent to a wired system. With a view to energy saving, sophisticated software is able to establish the distance between the control unit and each of the peripherals, modulating the output power according to it. Numerous measures such as FH (Frequency Hopping), TDMA (Time Division Multiple Access) and AES (Advanced Encryption Standard) guarantee its security and reliability against external attacks. The continuous dialogue between the control unit and the peripherals makes the system immune. The system is able to detect jammer-type attack attempts. The radio communication protocol allows a transmission distance of up to 1.5 km to be achieved in free air.
