Able Alarm

Please can anyone identify this and if so are there any manuals available?

Sorry only got a copy of the instructions now Equaliser 3 White plactic key operated box approx 12"w 8"h 3"d How do i upload a copy of the instructions

The plastic £20 Scantronic Panel went under the name Equizer and was sold by Gardiner (per ADI)

My first install was a diy key operated metal boxed 1 zone i bought from my elder sisters mail order catalogue when i was 16 years old. I fitted it and got paid cash, I thought this is great at the time but thirty or so years later i now cant shack off this abit. Then went onto A & G rs panels, Hilcare multizone expander with all the switches, Securit and the first Scantronic 9100 plastic 4 zone microprocessor panel for under £20. Reading this topic i have being reminded about just how old i am and how young most of you lot are.
