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 4 call buttons are available in the door panel, each able to call two
telephone numbers a primary number and a divert number (if the first is busy or not answered, the call can be diverted to a second
number). The standard GSM LITE intercom works on a 2G network. A 3G variant is also available (suffix
/3G
to the part number e.g.
Art.4811-1/3G
,
Art.4811-2/3G
etc.). Features of the system include:
• A dry contact relay output and push to exit input;
• A single open collector auxiliary output (
AO1
) and two auxiliary inputs;
• Dial to Open facility
(this feature enables up to 100 stored numbers to dial the GSM LITE intercom, the intercom panel will
not answer these calls, but will activate the door/gate relay without being charged for the call);
• Program both primary and divert number in a single text message;
• Program up to 5 dial to open (
DTO
) numbers in a single text;
• Delete a dial to open (
DTO
) number without knowing it’s stored location;
• Up to 5 possible auxiliary output modes (
AOM
);
• Programming carried out via SMS text messages or limited programming features using the GSM mobile app, the
Videx
SMS Wizard
.
SIM CARD SELECTION
A SIM card is required for this product but not supplied by Videx.
The GSM Lite intercom can only accept a standard size SIM card
(refer to the following SIM card size chart below), both a micro-SIM and nano-SIM are not suitable. 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, however if using a ‘Pay as you go’ we would recommend setting up an automatic top up to avoid running
short on credit and losing 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 website, as
this service is not provided by Videx

NETWORK PROVIDER SELECTION
It is imperative that for the reliable 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.
For UK customers, as an initial check we also recommend visiting the ofcom website
www.ofcom.org.uk
and follow the onsite links to
their online mobile coverage tool
(
ofcom broadband and mobile checker app
)
. This tool will advise on the best coverage for the main
network providers and other general queries that you may have about the service provider. For all overseas customers we suggest
consulting the website of the network provider that will be used to check the coverage in your area.
