IR-081C is a 4 wire oversized apartment station which is large enough to cover the hole left by many previous intercom stations, so there's no painting necessary. There are no standard mounting holes for IR-081C. Custom 2, 3, or 4 hole configurations are drilled upon request at a nominal extra charge, to fit your existing back boxes. Contemporary styling, featuring fog white color and pleasing lines, compliments most decors. Advanced circuitry and simple pushbutton operation make this the perfect station for use in large or small buildings.
