Aiphone GH-VAX Instructions

CCTV Interface Module for GH Multi-Unit Video Entry System
The GH-VAX is a video module that provides a connection for an external CCTV camera for viewing a wide area
surrounding the GH 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 GH-VAX module will be installed in the entrance panel, but
will not be seen.
ENTRANCE PANEL CONFIGURATION:
1. The GH-VAX module takes the place of the standard GH-VA module, and must be located in the
entrance panel.
2. A blank plate (GF-BP) is required to cover the GH-VAX, so it will be out of sight from the outside
of the panel.
3. The remote CCTV camera 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 GH entrance panel in the same manner as any other GH station, with
the GH-DA Audio Module connected directly with the GH-VAX, then all other modules connected
as designated in the GH Installation & Operation Manual.
5. Programming and operation of the GH entrance panel is the same as the standard GH panel, The
only difference is that the video signal is from a remote camera instead of resident in the panel.
