Can you recognise my alarm and tell me how to reset it?

We've had our alarm working for a while now, however after some work on the house it won't set itself.
When we arm it, it normally beeps quickly, then slows beeping when you leave, however it doesn't seem to set itself on..

Here it is, if anyone can give me the name and/or point me towards a manual that would be great, thanks.

Thanks, are there any dummy user guides to reset these?
(My electrician isn't great coming out a the best of times, let alone christmas)

What makes you think it needs resetting ? Work in house = something not working ! Enter code with everybody out, all doors closed if any , and what comes up on keypad ?

After some Google ing and frankly ****ing about I called someone in.
It's seems during the last bit of work the cable to a sensor got damaged.
(the next might not be 100% correct )
The cable has 8 wires in pairs, and 2 pairs were damaged, but managed to salvage a working pair from them.
I was also shown how easy it is to access the menu system.
So a few blown fuses and £20 sorted.
Thanks for pointing me in the right direction, though I couldn't have fixed it.
