Alarm Ringer Rutenbeck WK 955 Ap

The Rutenbeck WK 955 Ap alarm ringer provides a focused audible alert with a rated sound level of 92 dB, suitable for integration into alarm and signaling systems. Designed with a compact ABS housing and modest dimensions (80 mm × 65 mm × 30 mm), this unit accepts both AC and DC supply in the 30–60 V range and is manufactured in compliance with RoHS requirements. The combination of robust enclosure material and a clear, high-level output makes the WK 955 Ap a practical choice for installations that require reliable acoustic notification within limited space.

Advantages

The device offers a consistent 92 dB output ensuring that alerts are clearly audible in medium-noise environments. Dual compatibility with AC and DC supplies across a 30–60 V input range simplifies integration into various control panels and power architectures. The ABS housing provides impact and corrosion resistance for indoor applications, and compact dimensions allow installation in confined or space-limited mounting locations. Compliance with RoHS indicates reduced use of restricted substances.

How to use

Install the alarm ringer in accordance with the system wiring diagram and local electrical codes. Connect the unit to the control output using a suitable cable rated for the supply voltage; ensure correct polarity for DC connections and proper isolation for AC supplies. Mount the device on a flat surface using appropriate fasteners, allowing unobstructed sound emission. Verify the supply voltage falls within the specified 30–60 V range before applying power. After installation, trigger the alarm input from the connected control device and confirm audible output and proper operation.

Recommendations

For reliable long-term performance, place the alarm ringer in a dry indoor environment and avoid direct exposure to extreme temperatures or moisture. Periodically inspect mounting and electrical connections and confirm acoustic output during routine system tests. When integrating with other notification devices, evaluate combined sound levels to ensure compliance with local workplace and safety regulations.
