The 9627 is an intercom substation designed to be mounted behind the car operating panel by the elevator company. It is the functional equivalent of a standard 9620 substation, but without a faceplate. The substation includes a 3" speaker with acoustic baffle, an LED, (optional) an electronic board, and a mounting subplate.

The board provides circuitry for either momentary and/or maintained contact call-in button (provided by elevator company). The substation allows clear, hands-free, two-way communication and paging inside an elevator car. Board includes screw-driver adjusted speaker volume control. The 9627 will operate with the 9200, 9400 and 9600 systems.
