General Notes
 

The indicated values for volume correspond with our measurements in the factory. Those values may vary in connection to different resonance surfaces and spaces as well as the method of installation or mounting

Mechanical DC buzzers will need a higher current at the start than the indicated current rate

The indicated values of power are standard values.

EMV
Products which are labeled with "EMV" fulfill the requirements of EMC (electromagnetic compatibility), see following specifications:

- EN 5501 / EN 55014 / EN 55022
- IEC 801-2 / IEC 801-3.
- IEC 801-4 Sharpness of each is
  grade 3

The EMV symbol cannot be used by incandescent lamps

 

Assurance of characteristics

The technical characteristics of our products are procured conscientiously. A warranty is given only by special declaration in accordance to § 463 BGB. Liability occurred by absence of assured characteristics will only take place if the purchaser has been assured especially on the purpose to avoid this damage

By installation of direct current buzzers the radio noise voltage has to be considered after EN 55011/14/22. All direct current buzzers are available with a third connection for surcharge. This third connection is needed for a later installation of freewheeling diode. Buzzers labeled with "E" are noise suppressed by grad "N".

Measurements, weights, performance and illustration are subject to technical modification.
