External, wirelessly controlled optical-acoustic siren designed for use in intruder alarm systemsTwo-way wireless communication 868 MHz is based on AES-128 encryption Alarm signaling is carried out in two ways: optically and acoustically modulated sound signal with high volume (piezoelectric transducer 110 dB)
The device is battery-powered (4 x CR123A) or 12V DC
The external casing of the siren is made of high-impact polycarbonate, thanks to which it is characterized by very high mechanical strength and guarantees the aesthetic appearance of the siren even after many years of operationThe design of the siren provides a high degree of tamper protection (against opening and against detachment from the ground)
