Sirena CELEREST Electromechanical Siren
Product Description
The Sirena CELEREST Electromechanical Siren is designed for robust performance in outdoor environments, featuring an aluminium protective cap that increases resistance to atmospheric agents. Available in three sizes—miniCELEREST, CELEREST, and superCELEREST—this siren caters to various sound output requirements and is also offered in low consumption BA versions. For optimal effectiveness, it is recommended to install the device in a vertical position.
General Features
Operating at voltages of 12V ACDC and 24V ACDC for miniCELEREST, and 110V ACDC and 240V ACDC ±10% for CELEREST and superCELEREST, this siren is versatile and reliable. The BA versions operate at 24V DC ±10% and superCELEREST BA at 12V DC and 24V DC. The siren functions within a temperature range of -30°C to +40°C and has an IP44 protection rating. It is designed for intermittent service (ON 1 min. - OFF 10 min.) and continuous operation in BA versions, with insulation class II and an M16 cable gland.
Mechanical Features
The siren's body is made of self-extinguishing ABS with high impact resistance, and it includes an ABS sound diffuser and an aluminium protective cap. It is mounted using standard screws (not included). The CELEREST and superCELEREST versions are equipped with a motor protection thermal circuit breaker.
Acoustic Features
The siren produces a continuous sound, reaching its fundamental frequency shortly after activation. The frequencies are as follows: miniCELEREST at 1600±100Hz, miniCELEREST BA at...
