Outdoor siren with optical and acoustical signaling intended for use in intruder alarm systems. An acoustic signal is generated by means of the piezoelectric transducer. Construction enables high level of tamper protection (against opening and removing from mounting surface).

The electronics board of the siren is made in SMD implementation and protected by impregnation against unfavorable effects of weather conditions, what ensures high reliability of the device. High-impact polycarbonate enclosure, featuring a very high mechanical strength and guarantees aesthetic appearance of siren even after many years of using.
