RS PRO Panel Mount Buzzer, 24 V dc, 75dB at 1 m

If you need to add a buzzer to an electrical product, this one from RS PRO is ideal. It's made of stainless steel and has an IK04 (Impact Protection) rating, which means it's able to withstand a 250 g mass dropped from 200 mm. This makes it tough and well-suited for installation in public areas.
The buzzer produces an intermittent tone of 75 dB up to a one-metre distance, so you can hear it easily over most ambient background noise. It also features a flashing LED (light-emitting diode) light, so you can quickly identify it on a panel. The product has an operating temperature range of -20°C to +55°C, making it suitable for a variety of demanding applications, from sub-zero warehouses to hot manufacturing plants. A buzzer like this one is commonly used in vehicle and aircraft dashboards, as well as intercom systems in buildings. Engineers have tested this product for quality and safety.
