Pfannenberg – PRO 10 10-60V DC

The Pfannenberg PRO 10 10-60V delivers powerful and reliable audible signaling for demanding industrial applications. Designed with a rugged cast aluminium housing, it provides long-lasting performance in harsh environments while delivering excellent sound coverage and penetration through noisy industrial settings.

Furthermore, the PRO 10 10-60V produces sound levels of up to 116 dB(A) and incorporates Pfannenberg’s advanced 3D Coverage technology. As a result, warning signals reach a larger area more effectively, reducing the number of sounders required and helping to minimise installation costs.

The PRO 10 10-60V also offers exceptional flexibility through its multi-voltage power supply, allowing a single device to operate across a wide range of AC and DC voltages. Engineers can select from 80 integrated alarm tones, while three additional tones can be selected externally to meet specific application requirements.

In addition, the sound pressure level can be reduced by up to 30 dB, either internally or externally. This enables users to implement pre-alarm and main alarm functions, helping to warn personnel before a full-volume alarm is activated and reducing the likelihood of shock reactions.
