Installation
When the configuration is altered, the
system must be scanned again. Therefore
always switch off the system by means of
the rear power switch when a camera or
accessory is added or removed. Only
operating the power save button is not
sufficient.
Remark:
Only the inputs to which cameras are connected can
be selected or used by the monitor. It is therefore useless to
connect an accessory to an input to which no camera is
connected.
Monitor
On the back of the monitor the following can be
connected:
Cameras
Connect the camera to one of the camera inputs at the
back of the monitor (fig. B-1).
Correctly directing the camera at the object will be easier
when the monitor is temporarily installed at the camera
site.
VCR
For the recording and reproducing of image and sound a
video recorder has to be connected to the input and
output (
VCR-audio/video in/out
) on the back of the
monitor (fig. B-2).
The VCR output can also be used to connect other
peripheral equipment. For example, a video printer for
hard copies.
Extra monitor
You can connect an extra monitor to the
slave-output
(fig. B-3), by using the same twisted pair system cable.
The extra monitor gives exactly the same image and
sound as the basic system monitor.
In
VCR
mode, the slave monitor shows the image of the
last selected camera.
Alarm contact
The alarm contact (make (N.O.) and break (N.C.)) of the
monitor (fig. B-5) can, for instance, be used to start up a
video recorder, siren or telephone selector.
Cable
A 4-wire system cable (see specifications) is supplied as
standard.
For optimum picture and sound quality, a standard dual
'twisted-pair' (telephone) cable should be used.
There is an extensive range of plugs and tools available
in the hobby and professional trade to extend the cable.
Always ensure that the connection is made as shown in
figure C.
Caution:
The plugs used for the observation system have the
same dimensions as standard telephone plugs. Never connect a
telephone to the camera or system monitor.
The maximum distance that can be bridged (without a
cable extension adapter) between the monitor and the
cameras is 300 meters.
