Applications and Installation
The Hager SU212 12V Modular Bell is intended for electrical signalling applications requiring an audible indication. Its slim modular construction makes it practical for installation in compatible electrical enclosures where available space is limited.
The device operates at a rated voltage of 8–12V and must be connected to a suitable supply. Installation should be carried out by a competent person in accordance with the manufacturer’s instructions and applicable electrical regulations.
Alternative 230V Modular Bell
For installations requiring a mains-voltage signalling device, see the Hager SU213 230V Modular Bell. This alternative also occupies one 18mm module but is designed for a 230V supply rather than the 8–12V operating range of the SU212.
