2.1 Information on using the GSM/GPS Combimodule (optional)
SIM card used:
In order to use the GSM module, you require the SIM card of a mobile
phone supplier. We recommend using a card from T-mobile or Vodafone.
However, cards from other suppliers are also generally suitable. Since
pre-paid cards do not result in monthly charges, these cards are ideal for
the purpose. The current credit on the card is transferred with each SMS.
When choosing a pre-paid card, make sure that it does not have to be
removed from the device in order to top up the credit but can be topped
up from another mobile phone or ATM etc..
Roaming:
Make sure that roaming is activated on the SIM card used.
With pre-paid cards, the function may have to be enabled separately.
Call diversions/mailbox:
It is essential to make sure that all call diversions, automatic call back
and the mailbox of the SIM card used are deactivated. Otherwise, there
may be problems with switching by phone call.
Saving the number of the GSM module:
In order to assign the number quickly when there is an alarm message,
you should assign it to a name, as with every other entry in the address
book of your telephone. Since you may also have to access the number
quickly, you should ideally label it ALARM, then it will be stored at the
beginning of your address book. If you write alarm in the following way,
it will always be at the top of the list: AAlarm. The number must always
be stored with the country code (e.g. +44 for the UK) in order to access
it from abroad.
Target phone numbers:
Target phone numbers are the numbers which are contacted when there is
an alarm and can be used to control the alarm system by SMS or phone call.
Therefore, only select people who you can really trust. If certain persons
should be informed but are not to be able to control the alarm system,
this can be taken into account with the programming SMS (see installation
manual).
Controlling by SMS or phone call:
Each SMS sent by the GSM module results in costs which depend on your
network carrier. If you control the system by SMS or phone call, this always
produces a status SMS. For the actual control process not to cost anything,
the program selector switch can be positioned when the system is installed so
that the system can also be controlled by phone call. However, please note that
in this case a status message can no longer be requested.
