Product Overview The SMS Lite is a cellular remote-control device that uses text messages to provide up to four people with status conditions, notifications, and control options for its four switched inputs and two relay outputs.
The SIM card must be a standard “full size” card, not a micro or nano SIM. We recommend you insert the SIM into a regular cell phone and check that you can send and receive messages. Carefully remove the SMS Lite cover by prising the side panels close to the retaining dimples.
Inputs The SMS Lite inputs are to be connected to switches or mechanical contacts. The default input names are: INP1, INP2, INP3, INP4, which can be renamed. An input is active or ON when the input switch is closed and inactive or OFF when the input switch is open.
Basic Configuration To operate the SMS Lite, the device must have a mobile number registered as ‘Phone 1’ referred to as Ph1. You must register this number before you can configure any of the inputs or outputs. The SMS Lite can have up to 4 phone numbers registered.
Where the units can be ms, sec, min, or hr, and the maximum duration is 1 day. This is all that is required for the master phone number to receive notifications from the SMS Lite inputs and control the outputs.
You can assign a site name as well as naming each of the inputs and outputs and assigning phone(s) to these. The SMS Lite can be configured with up to 4 phone numbers allowing multiple user notifications and control options.
To program the Site name to Shed1, name Input 1 as Pump and set notification escalations to phones 1, 2 and 3. You can either send the SMS Lite 3 individual configuration text messages: e.g.
You can program a delay before the text message is sent by the SMS Lite. The trigger point / device that is connected to the SMS Lite must stay in that state for the ‘debounce’ time that is set, before the SMS Lite will send a text message alerting you of a status change.
Message Paths The following diagrams are examples of the message flows for the SMS Lite. They show the basic message flow, an example of a busy response, no response and the escalation flow to multiple phones. Example 1 - Phone 1 Alerted – Alarm Acknowledged...
It will begin at the top of the list the next time the input is activated. To force the SMS Lite to send the alarm message to the next phone number in the list. BUSY <input name> (e.g. Text: BUSY Pump) Up to 3 other phones can be programmed to receive a notification.
The SMS Lite will inform you of the version of firmware it is running. TEST e.g. Text: TEST This is a quick check to see if the SMS Lite is operational. It will display a led sequence and send the response: “SMS-Lite comms test succeeded!”...
Heartbeat – 1 short flash every two seconds - the SMS Lite is connected to the cellular network. Transmit OK – 5 short flashes - shows the SMS Lite successfully sent an SMS. Transmit Fault – 3 long flashes - shows the SMS Lite tried to send but there was a problem. Error Code Indication The LED also indicates error codes that can be used to help identify issues: Error Code 1 - 2 flashes - indicates the Modem will not power up.
6. The device is running on older firmware which can result in issue number 3 above. There are some actions that can be taken to assist QTech with diagnosing the issue. These involve carefully noting the actions of the indicator LED as it powers up and also counting the number of pulses in an error code when it is displayed.

If the device fails to do either or both of these, then there is a fault. If a fault error code is being flashed, see the previous section on Status LEDs to diagnose the fault, or contact QTech for assistance after working through the troubleshooting tips below.
Upgrading from the old 2.5G SMS Lite. Take care when transferring the old SIM card to the new 4G SMS Lite. If the new 4G SMS Lite fails to register on the mobile network, shown by error code 4, you may need to obtain a new SIM card compatible with the 4G network. The modem type is identified by the following printing on the daughterboard: “UC864-G”...
By sending ‘Status’ to the SMS Lite you can see the status of any of the inputs or outputs, this can help identify if the alarm escalation has been interrupted by a configuration change.
