Same as Vivian Conway on Optima XM?
My question is very similar to Vivian Conway March 2008 after turning off all power to instal new points my alarm just shows a red light on zone1 and the power light I have tried resetting but no response, a similar problem happened a few years ago and after about 3 days it seemed to right itself, can you suggest any answer to the problem
