Amazing, 15 year old battery, Dead, In 15 years you should have had 3 new batteries,
And the next person who phones me and says it cant be a battery fault it reads 12.62 on my multimeter will be hunted down and shot at dawn,
Oh by the way public, us Loyal alarm engineers really need to remember the the general public really do know best,
