Video Alarm Verification (VAV)

This section provides only general information about
the VAV option. Detailed information is in the manual
provided with the VAV Transmitter.
A Video Alarm Verification (VAV) transmitter (e.g.VTP-
50/Transpac receiver) is an add-on accessory that
permits video imagery of the area where an alarm was
detected to be transmitted on standard switched
network telephone lines to the monitoring location
using the same phone line and phone call on which the
alarm is digitally communicated to the monitoring
location.
The VAV transmitter connects to the control's handset
telephone line (via a modem) and connects to 2 relays
on a 4204 Relay Module: a "kissoff" relay, which signals
the VTP-50 to begin communication, and a "hold the
line" relay, which holds the phone line for 6 seconds to
allow time for the VTP-50 to make connection to the
Transpac receiver. In addition, a "camera" relay for
each camera is used to trigger the cameras connected to
the VTP-50.
(Connection diagram is for reference only. Refer to the Summary of Connections diagram and the
instructions accompanying the video transmitter being used for actual connections.)

Access Control Using ADEMCO VistaKey

VistaKey is a single-door access control module that,
when connected to the VISTA-120 provides access
control to the protected premises. The alarm system can
support up to 15 VistaKey modules (15 access points).

VAV Operation
After all messages have been sent to the primary phone
number during a reporting session, the control will
transmit the VAV report (609) to a 685 (revision 4.73 or
higher), which prepares the Transpac receiver to
receive images. The "kissoff" relay activates, causing
the VTP-50 to begin communication with the Transpac
receiver, and the "hold the line" relay activates, giving
the VTP-50 time to make connection to the Transpac
receiver without breaking connection with the central
station. The video image of the areas covered by the
zones in the "camera" relay zone list is then transmitted
to the Transpac receiver.
New alarms will automatically disconnect the video
transmission and will be reported to the central station.
