Buzzers

Mini Buzzer
This family of electro-mechanical buzzers is compact and easily mounted with its integrated screw and tab bracket.  Operating voltages range from 24 to 240 VAC.  Duty cycles are dependent upon on time and ambient operating temperature.  Decibel levels range from 70 to 90 dB but the application enclosure has a greater effect on the sound quality.  For environments with higher contamination, a version is available with wire leads and a barrier epoxy adhesive is applied to critical openings.

Notes
1. The "on" time may be reduced provided the maximum percent "on" time for the cycle remains the same.

2. 24vac buzzers and other versions exist but are not currently rated by ul. Other configurations or higher ratings may be possible but haven't been submitted for ul recognition.

3. The above information is a summary of the ratings granted by ul for this product family  for additional information or product capabilities contact an ark-les representative.
