Satel SPL-2010 R 120 dB Outdoor Siren The SPL-2010 R is an optical-acoustic siren designed for outdoor installation, equipped with super-bright LEDs and a piezoelectric transducer. Three modulated 120 dB sound signaling modes are available. The siren's enclosure is made of polycarbonate, ensuring high mechanical durability and an aesthetically pleasing appearance that remains unchanged over the years. The device is equipped with tamper protection against opening the enclosure or removing it from the wall, as well as against silencing the piezoelectric transducer by pouring mounting foam over it. The inner galvanized sheet metal enclosure provides additional protection for the electronics board and transducer against mechanical damage. Thanks to appropriate impregnation, the electronics system is also resistant to harsh environmental conditions. Features of the SPL-2010 R siren: acoustic signaling: piezoelectric transducer. Optical signaling: super-bright LEDs. Internal metal cover. Anti-sabotage protection against: damping the siren by covering it with mounting foam (optional: SPL-TO); detachment from the surface; opening; Technical data Environmental class: III; Housing dimensions: 298 x 197 x 90 mm; Operating temperature range: -35...+55 °C; Rated supply voltage (15%): 12 V DC; Average current consumption during acoustic signaling: 35 mA; Average current consumption during optical signaling: 250 mA; Weight: 1220 g; Sound pressure level: 120 dB ; Manufacturer code: SPL-2010 R.
