6. G-SWITCH-22 GSM Module identification
The
G-SWITCH-22
GSM module allows up to 300 individual users to
activate a maximum of two outputs on the module using their mobile
phones. These outputs can be used to open a gate, activate an alarm
system, turn on a borehole pump , etc. Activation can be either via a
missed call (no charge), or a pre-specified text message (SMS).
In addition, users can also be notified by SMS, of the activation of either
of two inputs on the module, in the event of an alarm activation, a power
failure , etc. An optional online interface allows for easy programming of
the module.
May require additional external switchgear
1. Introduction
The
G-SWITCH-22
GSM module uses the GSM mobile phone
network to enable remote control and communication between itself
and up to 300 users via their mobile phones. A valid, and activated
SIM card is required in order to use the module on the GSM network.
4. General description
When programming the
, each user’s phone number can
be set to:
&
Activate a specified output/s with a missed call;
&
Activate either output via a unique, user defined SMS;
&
Be notified by a unique, user defined SMS of either input being
activated
G-SWITCH-22
&
Programming of the module is password protected
&
All users calling or sending an SMS to the module need to
ensure that their Caller Line Identification is activated on their
phone to ensure that the module recognises the user’s
learned-in phone number
&
The module requires a power supply of 10-30V DC, capable of
delivering 500mA peak
&
Both outputs are potential-free, and rated to 30V DC @ 1A
&
Both normally-open and normally-closed contacts are provided
&
Inputs are activated by switching to negative

The housing of the
G-SWITCH-22
is weatherproof allowing it to be
mounted externally in order to pick up the maximum GSM network signal.
However, the unit can be mounted inside the housing of the device that it
is operating, such as the gate motor if the GSM network signal is adequate.
(refer to Section 11 – GSM network signal detection) The following section
describes the procedure for mounting the unit to either an internal or
external wall. If mounting the
G-SWITCH-22
externally, give consideration
to its location as it should not be within reach of unauthorised persons.
It is strongly advised that a pre-paid SIM card (with limited airtime) is used,
and that it is also password protected. These measures will give you peace
of mind as they will ensure that your SIM card will have little or no value
should it ever get stolen.
Record the IMEI of your
G-SWITCH-22
in the blocks provided in Section 6.
In the event that the
G-SWITCH-22
is stolen, you can use the IMEI
number to blacklist the
G-SWITCH-22.

10. Insert activated SIM card
10.2. Raise the SIM card
housing.
10.3. Insert the activated SIM
card and ensure that the
SIM card is correctly
oriented. Align the
cropped corner to be in
the correct position as
per the diagram on the
circuit board.
10.4. Once the SIM card is
inserted correctly in the
SIM card housing, lower
the housing onto the
circuit board. Then slide
the SIM card housing
locking mechanism down
to ensure that the SIM
card housing is securely
locked in place.
10A. Replace cover
10.5. Hook the top of the
edge of the cover onto
the top of the unit.
10.6.
Lower the cover and
press securely into
position.
11. GSM network signal detection
When powered up, the
G-SWITCH-22
signal strength
indicator LEDs will light up
indicating the GSM network
signal strength.
The GSM signal strength can be
determined based upon the
combination of the three LEDs
that illuminate:

The GSM signal strength may be enhanced by repositioning the
antenna. Ideally the antenna should be mounted externally, and away
from any sensitive electrical components.
The rear side of the
antenna has a double-
sided tape backing, which
may be used to affix the
antenna to a desirable
location. Please ensure
that the surface to which
you affix the antenna is
smooth, clean and dry, to
ensure reliable adhesion
The signal strength can be queried by sending the “request
signal strength” command p.xxxx.
CO
.SS to the module. The
querying phone will receive a reply SMS with a value 5
(strongest) to 1 (weakest) indicating signal strength
10.1. Slide the SIM card
housing’s locking
