tor (see 2.2. Main Unit, LED Indicator & Connector Functionality for more details).
7. Change the system language if necessary (see 6. SYSTEM LANGUAGE for more details).
8. Change the default SMS password (see 7. SMS PASSWORD for more details).
9. Set the phone number for Admin 1 (see 8. ADMINISTRATOR PHONE NUMBERS for more details).
10. Set system date and time (see 9. DATE AND TIME for more details).
11. Once the system is fully congured, it is ready for use. However, if you fail to receive a reply by SMS text message from the system,
please check the SMSC (Short Message Service Center) phone number. For more details regarding the SMS center phone number,
please refer to 17. SMSC (Short Message Service Center) Phone Number.
ATTENTION: The system is NOT compatible with pure 3G SIM cards. Only 2G/GSM SIM cards and 3G SIM cards with 2G/GSM prole
enabled are supported. For more details, please contact your GSM operator.
ATTENTION: We also recommend you to disable call forwarding, voice mail/text message reports on missed/busy calls and
similar services that might cause incorrect system operation. Please contact your GSM operator for more details on these services and
how to disable them.
NOTE: For maximum system reliability we recommend you do NOT use a Pay As You Go SIM card. Otherwise, in the event of insucient
credit balance on the SIM card, the system would fail to make a phone call or send SMS text messages.
NOTE: We advise you to choose the same GSM SIM provider for your system as for your mobile phone. This will ensure the fastest,
most reliable SMS text message delivery service and phone call connection.
NOTE: Even though the installation process of GS-500 is not too complicated, we still recommend to perform it by a person with basic
knowledge in electrical engineering and electronics to avoid any system damage.

4.GENERAL OPERATION
When a phone call is made to the phone number of the SIM card inserted in GS-500, the system will verify if the caller’s phone number exists
in the memory. If the caller is one of the 5 administrators or the phone number belongs to one of the 500 database users, the system will
reject the phone call, thus making the phone call free of charge, and open the gate. By ringing to GS-500 again, it will close the gate. If the
phone number is not recognized, the system will reject the phone call and ignore it. The GSM switch-gate controller can also control your
gate automatically in accordance with the scheduled time or by sending an SMS text message from the administrator’s phone number.
By connecting a sensor to one of the 3 inputs, the administrators can receive SMS text messages regarding the gates that failed to close
during the set time period.

9.1. Automatic Date and Time Synchronization
This feature enables the system to set the date and time automatically without the user being involved in this process. The system supports
the following methods of automatic date and time synchronization that are used automatically on system start-up and periodically (by
default – every 30 days):
• Via GSM network – Once enabled, the system automatically sends a date/time request to the GSM operator. This method is the
most accurate synchronization method. Some GSM operators might not support it.
• By SMS text message – Once enabled, the system automatically sends the SMS text message to its own phone number and
retrieves the date and time from the SMS text message reply, as the included date and time is set by the SMSC (SMS center). This
method is not as accurate as the synchronization via GSM network, but always eective.
By default, synchronization via GSM network is enabled. To disable/enable automatic date and time synchronization via GSM network,
please refer to the following conguration methods.

failure, the system will attempt to use the SMS text message method as a backup.

10. USER PHONE NUMBER DATABASE
The system comes equipped with a user database of 500 user capacity. When the phone number is set, the user will be able to control the
output (-s) by free of charge phone call. GS-500 user database allows to assign output C1, output C2 or both outputs (simultaneous control)
to a certain user. The supported phone number format is the following:
• International (without (+) plus) – The phone numbers must be entered starting with an international country code in the
following format: [international code][area code][local number], example for UK: 4417091111111.
GS-500 user database supports user validity and access restriction features. For more details, please refer to 10.1. User Validity and
Access Restriction.
Optionally, a user name can be set that typically species the owner’s name of a certain phone number, for example: John.
The phone number and user name (if any) are used when searching for a certain user in the database as well as they are automatically
added in the event log after the successful output control event (see 13. EVENT LOG).
