For Safety

Please follow these instructions as you install your DVS2 and

have them available during the life-time of the DVS2. Ifyou 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

applications and 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.

the current camera is displayed on the main monitor in seconds.

Use <1> to decrease the dwell-time and <2> to increase it, when

you are satisfied release <AUTO>.

Repeat this for all the cameras you need to change.

To set the global dwell-time on the SPOT monitor ... Press and

hold <SPOT> and <AUTO>. The dwell-time is displayed on the

main monitor in seconds.

Use <1> to decrease and <2> to increase the global dwell-time,

when you are satisfied release <AUTO> then <SPOT>.

Using the DVS2 with Alarms

TheAL8has 8 alarminputs, itsfunction istotell 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:

•only display the most recent alarmed camera or,

•introduce the alarmed camera into a special sequence with a 2

second dwell-time.

Then, once the alarms are all cleared it can either:

•hold the last alarmed camera on the main monitor,

•start the normal sequence on the main monitor or,

•return to the settings it had before the first alarm.

A flashing LED indicates that the corresponding alarm is active

or has been active. Pressthe numbered key to cancel this once the

alarm is cleared.
