How does it work?

 

 
The Cellswitch is a kind of cellphone you connect to an electronic appliance or device to enable you to communicate with 
it using your own cellphone. You insert a pre-paid or contract sim card into the Cellswitch and communicate with by 
sending it a SMS or by simply calling it, as you would SMS or call your friend. 
 
When the Cellswitch recognise your SMS or cellphone number it will respond in a certain way.  
 
Any Vodacom or MTN sim card may be used. 

 
 
How easy is it to use? 
 

Your cellphone communicates directly to your Cellswitch 100 with easy to understand SMS commands. 
 
Simply type a SMS with the words 

1234.On

 and send it to the cellphone number of your Cellswitch and your lights, 

geyser, irrigation system etc will switch on from any where in the world!!!  
 
Simply SMS 

1234.Off

 to switch it off again! 

 
Connect your Cellswitch to your gate or garage door and call it. You can now get access to your property or open the gate 
for the garden service without even being there.  
 
The call is free as the Cellswitch does not answer the call but simply recognises the calling number and disconnects the 
call automatically.  Please note the Caller Line Identification must be enabled on your cellphone. 
 

What about security? 

 
Your Cellswitch will ONLY respond to you and your family’s saved cellphone numbers. 
 
The

 1234

 in front of every SMS command is a private PIN number that you can change whenever you want. 

 

How easy is it to program?

instructions. 
 
This method is great for a body corporate to add and remove security access control cellphone numbers at security 
complexes. This eliminates the need for remote controls as the Cellswitch can remember up to 500 cellphone numbers. 
Every time someone moves in or out, the body corporate simply log onto our website, add or remove those people’s 
cellphone numbers, hit update and DONE! 
 

How many different devices can I monitor and control? 

 
With the Cellswitch 100 you can monitor two different devices and control one at the same time. In other words you can 
monitor your alarm system, mains power and open and close your gate with a single device. 
 
When your alarm trips, it will SMS and call you, your family and your neighbours notifying them someone is busy breaking 
into your house. You can then phone your neighbour and open the gate for him remotely to go and investigate the 
situation. 

 

Getting Started: 

 

Step 1 > 

USING YOUR CELLPHONE ensure that the PIN number of the SIM card is disabled and there is 

airtime available on the SIM card before inserting it into the Cellswitch.

Step 3>

Step 4>

Step 5>

 Phone the number of the sim card inserted into the Cellswitch. You will hear the relay ‘click click’ on 

the Cellswitch and your call will automatically be disconnected.  
 

Step 6>

 Send a SMS with the text 1234.On to the Cellswitch and the relay will ‘click’ only once this time, 

staying on. In both steps 5 and 6 you will receive a confirmation SMS back from the Cellswitch.
