WT-009 GSM Remote Control Device
COPYRIGHT ©2008 WITURA CORPORATION SDN BHD
WT-009 GSM Remote Control Device is an electronic board manufactured by Witura
Corporation Sdn Bhd that links to a SIMCOM 300 GSM module, supplied with it.
The purpose of this device is to be installed in parallel of the low voltage opening button
of an electric gate to enable it to be opened by means of a GSM phone.
It has a relay whose contact has to be connected in parallel with the button which opens
the gate. It has a White List of numbers who are enabled to open the phone, up to 64.
When the WT-009 GSM Remote Control Device receives a call, it will check to see if the
calling number is in the list. If it is in the list it will reject the call (so there will be no
charge – at least with today’s charging procedures) and click the relay momentarily.
1) Safe – nobody can clone your phone as easily as they can do with a standard remote
control
2) Flexible – you can add or remove anybody number in a minute with an SMS
3) Cheap – you don’t need to buy a remote control for each member of your family
4) Convenient – no matter if you change car, or if you have different gates to open.
Your phone will always be with you all the times your remote controls were
somewhere else!
Installation
To install the WT-009 GSM Remote Control Device you need to connect the 2 wires of
the relay contact in parallel with the gate opening button. The relay contact can stand
48V 1A maximum, this is enough for its operation but don’t try to switch higher
voltages or currents.
You also need to provide the power by means of 12 to 20 VAC or 12 to 26 VDC. The
power supply must be able to stand 2A. We supply a proper AC adapter. If you are not
using our AC adapter, make sure the power supply can arrogate 2A. Don’t use telephone
battery chargers! Most of them rely on the phone battery and are unable to supply the
power needed.
