How do I reset this burglar alarm?

[doughnut2020]

Moved into my house a while ago, I was given code for this alarm, but not sure how to change it.

Someone left the house and I want to change the alarm code, here is a photo of the panel

That's a gardtec keypad

Do you know your model number? It should be on the wiring panel

Once you know that you can download the user instructions off the net which will tell you how to change the code

This was the part of cont control pad that I could open, I couldnt see any writing on it.

There is also another muxh bigger with box in the garage with no writing whatsoever on it. and requires a very long screwdriver (which I dont have) to open it

It’s a 370/590 series

Thanks alot,
could you point me to the name? I am sorry, I do not know anything about this stuffs. If you can give me the name, I could find the operational manual online to change the code

I got 2 manuals:

and

https://www.sentrysecurity.co.uk/wp-content/uploads/2018/08/Gardtec-370-User-manual.pdf

I am very sorry if I am being slow, but I am still abit lost, I think its the Gardtec 370. but I will try, the manual is still a bit confusing for me on changing the code. If anyone could simplify the instructions, that will be great. I will battle with the manuals for now.

Google “ gardtec 370 user manual “

This may simplify it for you.
Take your time changing codes

I followed the manual instructions but still got issues. When I entered my code, it gave me the:

'E ' System Full Setting


Then I am stuck from there because I cannot follow the instructions any further, perhaps the code I have is just a user code and not the matser code?

I have printed that page and been trying it

From Nu
Enter code number and press no until you get Uc
If you can not get to Uc then the code number you have is not the master code and you will not be able to change the code.
Only way to do this would be a default of code.

Yea, I am sure I do not have the master code... I probably just have a user code, How can I get a default code?

Control panel will need to be defaulted.
There are two methods,but if you do not know what you are doing this would mean the whole control panel would require to be completely reprogrammed for all zone functions and timers etc. Be careful do not reset unless you feel confident that you can sort.
