Exepd Buzzer Type AB1-S3

  • AB1-S3
  • Power supply
  • ATEX

The Exepd type AB1-S3 buzzer is used to provide alarm signaling – via a piercing, acoustic signal – to safely warn of possible hazards in explosion-hazardous areas.

A high IP protection rating and a corrosion-resistant stainless steel housing ensure a long service life of the device, even in aggressive environmental conditions. The buzzer can be used in a variety of applications in explosion-hazardous areas. Thanks to its approval as a device, it can be mounted directly on the front of a machine – without the need for additional certification.

It has also been tested for installation in certified control panels with Ex e, Ex t, and Ex d protection.

Note: The lock nut is not included in the scope of delivery.
