How to use

Mount the call button module into the compatible intercom frame according to the intercom system’s installation instructions. Ensure power to the intercom is switched off before fitting the module.

Press the button to initiate a call or signal as defined by the connected intercom unit.

Recommendations

For reliable operation, use the module within the environmental conditions specified by your intercom system and avoid exposure to direct water ingress. When replacing an existing module, match the mechanical dimensions and mounting points to ensure proper fit. Periodically check the button for mechanical wear and clean the surface with a soft, dry cloth; avoid abrasive cleaners or solvents.
