How to use

Install the intercom following local electrical codes and the manufacturer's wiring schematic for the building's access control or telephone system. Secure the unit to the chosen mounting surface using appropriate fixings for the wall material and ensure the wiring is routed through a protected conduit or cable entry. Connect the audio and power lines to the corresponding terminals and verify continuity before finishing the installation. After powering the system, perform an audio check from the external unit to the indoor station and adjust volume levels if supported by the connected system. Regularly inspect mounting and cable entries for signs of wear or moisture ingress.

Usage recommendations

For best performance, mount the intercom in a sheltered location away from direct exposure to rain and extreme weather. Use corrosion-resistant fixings and maintain a clear path for sound by avoiding obstructions directly in front of the microphone and speaker openings. Periodic visual inspections and cleaning of the stainless steel surface will preserve appearance and function.
