Optima XM6

[Guest DSPUK]

I am in the process of fixing up a house which has a XM6 alarm panel fitted but the last occupier never left the alarm pin code. I have a user manual for a Optima XM and set about resetting the NVM.

According to the instructions it goes

1 remove mains supply and open front panel and cause alarm condition

2 disconnect battery - SCB should sound.

3 remove wires from term 9 and 19

4 loop 9 and 19 and reconnect power.

5 the panel will now power up with no alarm condition.

EXcept

at 2 no external sounder or bell.

but at 4 everything went off and even the factory code 0123 didn't work.

Question

1 is my manual for a earlier model or have I done something silly.(more than likely)

This panel was fitted by the MEB in 94 so it's about 10 yrs old and last service was 97.

Be gratefull for any advice.

Thanks Dave
