Site Survey

It is strongly recommended that a Site Survey is conducted prior to in-

stallation of a VDN Dualcom to confirm that adequate VDN signal strength

is available at the site.

Call a Help Desk. See page 10. Ask for a VDN signal strength prediction. For

this, you will need to have the Post Code of the site available. This will tell you

if there is VDN radio coverage at the proposed site.

If there is no VDN radio coverage at the proposed site, the Dualcom’s VDN

alarm reporting path will not operate. If your GSM mobile telephone operates at

the site you could consider using a CS2000 GSM Dualcom. Contact CSL for

more information.

You can use a Dualcom, aerial & fully charged battery to survey the proposed

site for the point of strongest signal. You can also use a portable CS1051 or

‘Pakit’ test set to show the VDN signal strength at the proposed site.

See Page 11 ‘Aerial Siting’ for more information. Make a note of this point and

use it when installing the Dualcom aerial.
