  • A Cellswitch is a small device containing a sim card that is installed inside any gate motor. This enables you to open the gate by simply phoning it.
  • A Wireless Intercom is a stainless steel gate station containing a keypad, speaker, microphone and sim card. It has the same basic features as the Cellswitch, but in addition, if someone presses your house/flat number (i.e. 151) it will make a call to your cellphone or land line during which you can speak to the person at the gate. You can open the gate by pressing 1 for main and 2 for pedestrian before the call is automatically ended.

    You can also change features like the maximum call duration, keypad access control number and speaker and microphone volumes from the login website.

  • After you registered your Cellswitch or Intercom on the website, you will be able to configure and manage it remotely from anywhere.
  • The configuration and access control numbers are kept in your account on our secure servers.
  • When you click on 'Update' the server connects to the Cellswitch or Intercom and copies the config file onto the device.
  • Request the current airtime by sending the following sms to the device: 1234.airtime
  • There is no software that needs to be installed on your pc, everything is done by logging on to our secure website.
  • We have been providing this service for more than 13 years and database backups are made on regular intervals. A small amount of the device's airtime is used every month to pay for the service.
  • We do have a premium service available for real-time monitoring and control for assets and where a large number of devices needs to be managed.

  • Please take a note of the 2015 T&C's for our monthly service fees for Cellswitches and Intercom Systems.

  • We recommend that you load R200 airtime per year on a Cellswitch to cater for platform service charges, alarm/notification sms's and data. The system will notify you when airtime drops below a specified value that you can set in the 'Email Notification Options' section.
  • The option of a fixed annual fee of R350 is also available so that you will never have to worry about managing airtime on cellswitches again. With this option your device will always be running the latest software and security releases.

  A new un-registered Cellswitch is in 'Install' mode. This means
  that you can phone the device directly after installation.
  It will open the gate to any number that phones it before
  it is registered on the website.

  • Things to keep in mind
     - Check the signal strength. Sms 1234.signal to the device. 
        It needs to be between 20 and 30.

     - Check the airtime. Sms 1234.airtime to the device. 
        It is recommended to load R200 once a year.

        - Old email address.
        - New email address and password.
        - Owner contact detail to be verified against record entries.

        - Current email address where the device is registered.
        - Device Name and Cellphone number.
        - Email address where the device needs to be linked to.
        - Owner contact detail to be verified against record entries.

  • The Cellswitch or Intercom does not want to update! Phone the device and determine if it rings once and disconnect. If it goes directly to voice mail, check the 'Calls goes directly to voice mail' section below. If you hear one ring and it disconnects automatically, make sure that there is normal airtime available on the sim by sending it a sms 1234.airtime If you do not receive a sms back, the airtime have most probably ran out. Log onto your online banking and load airtime on the cellphone number of the Cellswitch or Intercom. The Cellswitch uses about R120 airtime per year. After you verified the airtime, check that the signal strength is between 20 and 30 by sending the following sms: 1234.signal

  • When I phone the device, it keeps on ringing and does not want to open the gate! It is probably a Contract sim. Contact the service provider (i.e. Vodacom or MTN) and ask them to enable the CLIP 'Calling Line Identification Presentation' of the sim. The CLIP is usually enabled by default on 'pre-paid' sim cards only.

  • When I phone the device, it rings once but does not want to open the gate. My number is programmed onto it! Check that your cellphone's 'Caller ID' is activated. Any 'No Number' calls will be ignored.

  • Calls goes directly to voicemail! Disconnect power from the device for 10 seconds and check that the led starts flashing after 10 seconds. If the led does not start to flash, check that the sim and antenna is connected properly.

  • The LED stays on and does not start to flash! Check that the sim card pin code is disabled. Remove the sim and clean the contacts.
