Setup overview
You will need:
SIM card:
SIM must operate on the GSM (2G) network for this version. Check with your SIM supplier.
Credit on the SIM (we recommend automatic top-ups)
The SIM is not PIN protected
The SIM is set to disable voicemail
Avoid SIM cards that deactivate automatically if the SIM is not used often. If your G031 is likely to
be unused for long periods of time, you will have to send the G031 an update request periodically to keep
the SIM card active. The time limit is often three months.
2. Power supply cable: long enough to reach your device in its final location.
3. Check there is mobile network reception for your SIM card in the location that your device will be
installed (you can check the SIM card in a mobile phone).
4. Temperature sensors (included) which come in 1, 2 and 6 metre lengths and can be shortened or
extended (we recommend a maximum of 8 metres).
5. Optional liquid cell 12.0V battery: Can be plugged into G031 for backup power.
Installation
1. Download and install the APP https://www.quark-elec.com/downloads/APPs/
2. Select G031 location: location must be indoors and not exposed to water or high humidity.
3. Connect the relays outputs (if required): check relay setup for whether you want relays in normal
open (NO) or normal closed (NC) position.
See back page.
4. Connect alarm inputs (if required) to the correct terminal: alarm inputs (INT) 1/2 will activate relay 1/2
respectively. The G031 is compatible with inputs that send signals as a switch (by closing the circuit) and
alarm inputs that send a low voltage signal.
5. Connect temperature sensors by inserting the connector block into the slots at the back of the G031.
Good practice is to label each sensor and its corresponding relay. This will help later on.
6. Insert your SIM into the G031 device (make a note of the SIM number first for reference).
7. Connect to power: Check LEDs are working correctly.
Blue Network LED: LED will flash blue at start up as it is connecting to a network. Once
connected, the LED will flash once every 2 to 3 seconds.
Red System LED: will flash at 1 second intervals once the system has finished initialization. The LED
will not flash while the G031 is processing a command.
8. Hold down reset button for 10 seconds.
9. Register the main phone number that will control the device within 10 minutes of powering up
the G031 by texting ‘88888888’ from your chosen phone to G031 SIM card. If registration is successful,
the module will reply with ‘Your phone has been registered’. If unsuccessful, the module will reply with
‘registered disabled’. If registration is unsuccessful, Hold down reset button for 10 seconds and
reattempt registration within 10 minutes. The system LED will flash at one second intervals once the
registration is completed. You can add up to three additional control mobile phones (check the manual for
full list of text command codes).
You can send commands and receive updates by SMS text or the text generating android APP.
Remember; the device processes one command at a time. Each command will have a reply to
confirm the command has been received and executed. You must wait for a reply message before
sending another command.
(This is an overview only. Familiarize yourself with the manual before installation.)
