Purchase now: Pfannenberg 23350630000 PA 5 Industrial Sounder
Purchase now: Atlantech Drives provides you the Pfannenberg 23350630000 (Model: PA 5), a high-output 105 dB(A) Sounder from the robust Patrol series. While standard sounders (like the PA 1) are sufficient for control rooms, the PA 5 is engineered for large manufacturing halls, steel mills, and outdoor yards where high background noise levels prevail. Operating at 230 V AC, this device ensures that your critical safety alarms and process warnings are audible over the roar of machinery, preventing accidents and reducing reaction times.
Technical Specifications and Acoustic Coverage
The PA 5 delivers a sound pressure level of 105 dB(A), providing a significantly larger coverage area than 100 dB models (remember, the decibel scale is logarithmic; +5 dB is a massive increase in energy). It features 80 selectable tones via internal DIP switches, allowing for full customization of the alarm strategy. The housing is constructed from impact-resistant, UV-stabilized polycarbonate/ABS, achieving an IP 66 / NEMA 4X rating, making it impervious to heavy rain, dust, and washdown jets.

Expert Installation Advice: The «15dB Rule»
To ensure an alarm is effective, it must be at least 15 dB louder than the ambient noise. Expert Tip: If your factory floor averages 85-90 dB (typical for metalworking), a 100 dB sounder is borderline. The PA 5 (105 dB) provides that critical margin of safety. Additionally, utilize the device’s «Volume Control» (internal potentiometer) only if installed in a smaller confined space to prevent hearing damage to nearby operators.
Frequently Asked Questions (FAQs)
Q: Can I synchronize multiple PA 5 sounders?
A: Yes, for large open areas where multiple sounders are needed, they can be wired to flash/sound in sync to prevent the «disorienting echo» effect.
Q: Is it suitable for fire alarm systems?
A: Yes, the PA 5 is compliant with EN 54-3 (Fire detection and fire alarm systems – Sounders), making it a certified component for building evacuation systems.
