WIRELESS OUTDOOR SIREN ARA13-W2(868 DAHUA. Compatibility: DAHUA wireless alarm systems ; Sound pressure level: 110 dB ; System operating frequency band: 868 MHz ; Radio communication range (in open area): max. 1600 m ; Color: Red ; Power supply: 4 x 3 V CR123A battery (included), 12 V DC ; Maximum current consumption: 420 mA ; Battery operation time: 3.4 years ; Operating temperature: -25 °C.. 60 °C . Weight: 0.9180; Length: 255; Width: 240; Height: 65; Outdoor, wirelessly controlled optical and acoustic siren designed for use in intruder and hold-up signaling systems. Two-way wireless communication 868 MHz is implemented based on AES-128 encryption. Alarm signaling is implemented in two ways: optically and acoustically modulated with a high-volume sound signal (piezoelectric transducer 110 dB). The device is battery-powered (4 x CR123A) or 12V DC. The external housing of the siren is made of high-impact polycarbonate, which is characterized by very high mechanical durability and guarantees the aesthetic appearance of the siren even after many years of use. The siren's design provides a high degree of anti-sabotage protection (against opening and against removal from the mounting surface). Compatibility: DAHUA wireless alarm systems. Sound pressure level: 110 dB. System operating frequency band: 868 MHz. Radio communication range (in open space): max. 1600 m. Selected functions: Two-way communication. AES-128 data encryption. Protection against jamming through frequency switching ensures reliable transmission.
