For Safety
Please follow these instructions as you install your DVS2 and
have themavailableduringthelife-timeofthe DVS2. If you have
any problems contact your supplier or telephone Baxall’s
Technical Support Department on +44 (0)161 406 6611.
WARNING: INSTALLATION IS ONLY TO BE CARRIED OUT BY
SUITABLY QUALIFIED AND EXPERIENCED
PERSONNEL
WARNING: ONLY USE THE DVS2 WITH THE CLASS 2 POWER
SUPPLY PROVIDED AND DO NOT ATTEMPT TO USE
THE POWER SUPPLY FOR ANY OTHER PURPOSE
The DVS2 is designed for use in general purpose CCTV
applicationsand must not be usedfor intrinsicallysafe or medical
applications.
Do not exceed the voltage and temperature limits given in the
specifications. Only use the DVS2 in a clean, dry, dust-free
environment.
Unpacking
Keep your packaging for use if your DVS2 is stored for a time or
needs to be returned for whatever reason. The packaging should
contain:-
» The switcher, either:- the DVS24 with 6 keys,
or the DVS28 with 10 keys.
» A mains-socket mounting +12V DC power supply (class 2)
» These instructions
If any of the items are missing or damaged then inform the
suppliers and carriers immediately, and do not attempt to use
your DVS2.

The DVS2
Your DVS2 takes either 4 or 8 camera inputs which it switches to
two monitors. You can select cameras by pressing the relevant
numbered key. There is also an AUTO key which starts an
automaticsequenceonthecurrentmonitor.Thissequencedisplays
all the cameras in numerical order and automatically skips any
unused inputs.
You can sequence both monitors at the same time, with each
displaying its own sequence. The time spent on each camera in a
sequence is called the dwell-time, this can be varied from 1 to 60
seconds. On the main monitor you can change the dwell-time for
each camera separately, however on the spot monitor the same
dwell-time applies to all cameras in the sequence. This is called a
global dwell time.
You can also link the DVS28 to 8 alarm inputs (the DVS24 to 4)
by using it with the AL8. The available response options are
described later in these instructions.

Connecting your DVS2
Make all the video connections using 75ohm coaxial cable with
BNC connectors on each end.
When you are ready to connect your DVS2, refer to figure 2 and
follow the instructions given below:-
» Connect a cable from the connector labelled MAIN to your monitor
or VCR.
» Connect cables from the cameras to the numbered video-input
BNCs.
» Plug the jack-plug from the 12V DC power supply into the
jack-socket marked 12V DC.
» Plug the power supply into a suitable mains power outlet.
» Switch on the cameras, monitor and DVS2 (at the mains power
outlet).
Note: We have provided a supplementary earth terminal on the
rear panel, please ask Baxall Technical Support if you need
further information.
Switching On the Power
When you switch the power on, your DVS2 may start by
displaying a sequence or a single camera. If it cannot find any
camera inputs then it scans rapidly through the camera selection
LEDs but does not display a picture.

Using the DVS2 with Alarms
TheAL8 has 8alarminputs, itsfunction isto tell theDVS2 which
of the alarms are active. The DVS2 assumes that
alarm 1 = camera 1, alarm 2 = camera 2 and so on. When only
one alarm is active the DVS2 shows the alarmed-camera on the
main monitor. If two or more alarms are active it can either:
• onlydisplay the most recent alarmedcamera or,
• introducethe alarmedcamera into a special sequence with a2
second dwell-time.
Then, once the alarms are all cleared it can either:
• hold the last alarmedcamera on the main monitor,
• start the normalsequence on the main monitor or,
• returnto the settingsit hadbefore the first alarm.
A flashing LED indicates that the corresponding alarm is active
or has been active. Press the numberedkey to cancel this once the
alarm is cleared.
