Very Old Optima Mk 4

[smudgersmiffy]

My parents had an alarm system installed in 1990 (I think).

A few months ago, there was a powercut and the internal battery was flat, so they lost their programmed code. We have since replaced the internal battery, so we'd now like to re-programme their code. It has revered back to the default 0123.

There is no brand name/model number on the outside of the unit, but on the back on the circuit board, it is marked "Optima Mk4".

Unfortunately, I am unable to find anything about this on-line ('cos it's so old I guess!).

Thanks for your help!
