This Supercelere electric siren is a powerful electromechanical signaling device for acoustic warning on a 24 V DC system. The siren delivers a single continuous tone with a sound level of 113 dB(A) at 1 m and a frequency of 900 Hz.
An internal electric motor drives a fan, which produces a long, whistle-like signal tone. The stated audible range is 800–1,000 m. The BA version is intended for continuous operation and has a power consumption of 5.0 A at 24 V DC, as well as an allowable voltage tolerance of ±10 %.
The siren has a nylon construction and a black housing. The product measures 185 × 156 × 140 mm, with the housing having an outer diameter of Ø140 mm. The net weight is 1.50 kg. The IP43 protection and an operating temperature range from -30 to +40 °C make the siren suitable for demanding signaling tasks.
Mounting is carried out using the integrated bracket, which has an Ø8.2 mm mounting hole. The supply cable is routed through the M12 cable gland, secured with the cable clamp, and connected to the internal terminal block. Mounting screws are not included, and the electrical installation must be performed by qualified personnel.
The model is the Supercelere BA from the Sirenas ELECTRA product line and has manufacturer no. 42057. It is designed in electrical safety class II and is CE and UKCA marked.
