Velleman Electronic Siren of 125dB SV/PS5

This wired siren is an electronic alarm system used for various applications, such as security systems, warning systems, and emergency signals. It is made of durable ABS material, ensuring a sturdy construction and long lifespan.

The siren operates on a working voltage of 6-12 VDC, which means it is compatible with a wide range of power sources. At a supply voltage of 12Vdc, the siren has a current consumption of approximately 1300 mA.

The oscillation frequency of the siren ranges between 0.9 and 4 kHz, generating a loud and clear sound output with a sound pressure level (SPL) of 125 dB at a distance of 1 meter. This high sound level makes it ideal for situations where a powerful warning is required.

The dimensions of the siren are approximately 100 x Ø 110 mm, with a weight of 370 g. It can be easily mounted using the mounting holes of 52 x 49 mm.

This siren is designed to operate over a wide temperature range, from -30 °C to +85 °C, making it suitable for both indoor and outdoor applications.

The product has an IP rating of IP50, which means it is dustproof and offers some protection against the ingress of water, but is not completely waterproof. It is advisable to place the siren in a protected environment for maximum durability.

The siren has an autonomy of at least 6 hours at a supply voltage of 12 VDC, which means it can still generate sound signals even in the event of a power failure.
