Keen to keep everyone aware of hazards in your workplace? Choose this electronic sounder from Eaton. It's an acoustic accessory that supports a buzzer on your panel, giving off an alert right from a machine's controls. Thanks to its BA9s socket, you can simply plug a buzzer in place for quick alarm assembly. A continuous tone means the device keeps playing to make sure staff get the message in settings like warehouses or manufacturing facilities. You'll have no trouble mounting it, as it slides into a standard 22mm diameter cutout.

• Compact head diameter of 29.7mm means it tucks onto busy panels
• Works with AC and DC voltages at 250V for wide power-source compatibility
• IP40 rating to indicate protection against objects larger than 1mm, including wires
• Handles surge voltages up to 4kV, so shakes off power faults

No, it comes as a complete device, so it's ready to take your buzzer and get straight to work.

This device takes solid and stranded conductors between 0.5 and 1.5mm², so it's a versatile fit for standard alarm setups.
