The Orno OR-DP-ML-131 is an electromechanical bell that runs directly from the 230 V mains supply. Its red painted steel cover provides IP44 protection against dust and water splashes, making it suitable for use in indoor and sheltered outdoor locations.

The bell produces 90 dB of sound output and connects to wired signalling systems via surface mounting. It has no volume adjustment — the output level is fixed, making it straightforward to deploy as an alarm sounder or access-control bell.
