Innovation meets robustness

The Protect series marks a significant advancement in signalling technology. Standing for Pfannenberg Range of Toughness & Excellent Coverage Technology, Protect represents a new standard of robustness, thanks to its practically unbreakable
die-cast aluminium housing.

Designed to withstand the toughest industrial and outdoor conditions, the devices are tailored to meet the diverse needs of a wide range of industries and applications, including fire alarm, marine, machine safety, functional safety, Ex/ATEX, and
functional safety in explosive areas.

The Protect series includes a single sounder as well as a sounder/light combination with six different lens colours. The combined devices are optionally available with Xenon or LED* light. Versatile and adaptable, the devices are certified
according to different industrial standards to fit individual needs.
 

The advantages of all devices at a glance:

• Excellent robustness – Cast aluminium housing guarantees long-lasting use in tough applications 
• Selectable tone – 80 different tones, 3 additional tones externally selectable
• Pre- & main alarm – Preventing shock reactions by pre-alarming due to reduced sound pressure level
• Safe & easy handling – Designed with unlosable seal and screws to significantly shorten wiring and installation times
• Outstanding perceptibility – Ideal radiation characteristics and high penetration of acoustical obstacles reduce the required number of devices
• Reduceable sound pressure level – Reduction of sound pressure level up to 30 dB, internally or externally selectable
• Two-sense alarming – Barrier-free and safe signalling due to 2 technologies (combined devices - audible/visual)
• Multi-voltage-power supply – Made to connect with different voltages, no need to stock various units
• High safety standard – Fullfills the ISO7731 requirements
