The GT-VAX is a video module that provides a connection for up to 2 external CCTV cameras for viewing
the area surrounding the GT entrance panel. When a visitor calls from the entrance station, the view from
the separate CCTV camera will be seen on the tenant's monitor station. The tenant has the option to switch
over to a second CCTV camera (if equipped). The GT-VAX module will be installed in the entrance panel,
but will not be seen.

WIRING DIAGRAM:
ENTRANCE PANEL CONFIGURATION:
1. The GT-VAX module takes the place of the standard GT-VA module, and must be located in the entrance
panel.
2. A blank plate (GF-BP) is required to cover the GT-VAX, so it will be out of sight from the outside of the
panel.
3. The remote CCTV camera (powered locally) connects to the back of the GH-VAX module as shown
below. The camera location is intended to provide a wider view of the lobby or entry area, other than a
direct frontal view of the visitor.
4. Build the remainder of the GT entrance panel in the same manner as any other GT station, with the GT-
DA-L Audio Module connected directly with the GT-VAX, then all other modules connected as
designated in the GT Installation & Operation Manual.
5. Programming and operation of the GT entrance panel when using the GT-VAX CCTV interface module is
the same as a standard GT panel.
