Comelit Usa 1122/A Relay for Supplementary Buzzer

Product Description

The COMELIT USA 1122/A is a relay designed to support supplementary buzzer functionality within intercom systems. It serves as an interface component that triggers an external buzzer when a door station call is received, extending audio notification beyond the standard intercom handset or monitor. This accessory is intended for installation by licensed low-voltage technicians, security integrators, or electricians working on residential or commercial intercom installations. The unit is sold individually and integrates into COMELIT intercom system wiring to expand alert coverage in larger spaces or areas where the primary intercom tone may not be audible.

This relay is categorized as an intercom accessory and is suited for installations where occupants need supplementary audio notification in a secondary room, office, or remote area. It is a discreet add-on component that connects within the intercom system infrastructure without requiring a separate power supply independent of the intercom network. Installers working on multi-room residential setups or small commercial entry systems will find this relay useful for extending buzzer coverage without replacing core intercom hardware.
