Hi
Had system in for 10 years but on two occasions (one a number of years ago and one now) the key pad (ACT5e) is tripping the resettable fuse on the board
All worked fine until earlier this week - now on connecting the keypad to the board the board trips and has to be reset (powered off and on again)
no shorts detected
no obvious cable degradation etc
key pad works ok when powered up on its own from a separate supply (but I've not measured current draw etc )
Thoughts
is the resettable fuse a bit sensitive - do they degrade over the years ?
All ideas welcome
