SYSTEM INTRODUCTION

The system is designed to work on the same technology as mobile phones. It enables a
call to be made from an entry point (Door, gate etc), to any telephone number (mobile or
land line). Up to 50 call buttons can be connected to the door panel, each able to call two
telephone numbers (If the first is busy or not answered, the call can be diverted to the
second) or with the additional divert facility enabled it is possible to have up to 10 call
buttons each with 1 primary number and 5 divert numbers. Features of the system include
a dry contact relay output, an open collector auxiliary output, push to exit input and
switched 0V auxiliary input. Programming of the telephone numbers and additional
features can be carried out via text messaging or PC using a specially designed Windows
program. An additional access control feature for up to 250 telephone numbers is also
available on the system allowing a number of callers to open the gate/door simply by
dialling the telephone number of the intercom panel (The intercom panel will not answer
these calls but will activate the relay output).
A SIM card is required for this product but not supplied. It is recommended to choose the
SIM card which has the best coverage for the area in which the intercom panel will be
installed. Both contract and 'Pay as you go' SIM cards can be used but if using a 'Pay as
you go' we would recommend setting up an automatic top up to avoid running short on
credit and loosing the use of the intercom panel. Alternatively if you already have a
contract mobile phone it should be possible to get a second SIM card and telephone
number on the existing account. For more information contact the SIM card provider or
visit their web sites.
Network provider selection: It is imperative for the reliably operation of the system that
the best network provider for the area is selected. Problems such as network
disconnection can occur if the provider has signal or interference problems for that area.
We would recommend using a GSM signal strength meter to survey the intended antenna
location. Contact Videx for more information on where to purchase a tester. As an initial
check, also go to www.sitefinder.ofcom.org.uk and enter the postcode of the intended
installation. This will show all transmitters in the area. It is advised to choose the closest
one or if there are many then choose a transmitter working on 900MHz as this frequency
works best through obstacles such as walls, buildings etc. The antenna should always be
mounted vertically at the highest point possible. Metal structures and sources of
interference such as power cables, control panels etc can affect signals and so the
antenna should be mounted away from these.
When registering a new SIM you may be asked for the IMEI number. This is the unique
serial number of the GSM intercom and can be found on the rear of the module just below
the SIM holder on a white label. It's the long number below the barcode.
