Pfannenberg – PRO L 10 10-60V DC

The Pfannenberg PRO L 10 10-60 is a robust combined sounder and beacon designed for demanding industrial, marine, and safety applications. As part of the Protect Series, it combines powerful audible and visual signalling with exceptional durability, making it ideal for harsh indoor and outdoor environments.

Built around a virtually unbreakable die-cast aluminium housing, the PRO L 10 delivers reliable operation in challenging conditions while providing effective warning signals that can be both heard and seen. The unit is available with either Xenon or LED beacon technology and a choice of lens colours to suit specific signalling requirements.

Furthermore, the PRO L 10 incorporates Pfannenberg’s advanced acoustic design to maximise sound penetration and coverage while reducing the number of signalling devices required across a facility.
