Loud and reliable alarm

This alarm has been in place on our fuel storage site for months. The 119dB volume carries well, and the 380V motor runs fine. A reliable explosion-proof alarm.

Perfect motor alarm

We needed a tough alarm for our chemical plant, and this explosion-proof motor alarm does not disappoint. The 119dB volume is seriously loud and cuts through all the background noise. The cast aluminum housing feels super sturdy and the IP44 rating gives us confidence in harsh environments. Plus, the seller provided great service—answered all my questions quickly and shipped fast. Highly recommend!
