Honeywell Galaxy II alarm system

[m a r t i n]

Back in March I got a warning on the keypad that the battery was low, so went and replaced the 12v battery in the box in the eletrical cupboard. Since then the keypad has been blank, when I disconnect the large battery the alarm triggers outside so I know there is no fault there. I've read the full book on it to see if theres a fuse thats possibly blown that feeds the keypad, I've checked the fuses and all seem ok. Anyone any idea on what could be wrong?

When you say blank, do you mean no power to the keypad ? You need to test the fuses with a meter, as a blown fuse may not be something that's visible.

Yeah, no power at all to the keypad. I've ordered new fuses, but could one of them being blown completely stop power going to the keypad?

Yes, the aux fuse. It would likely be supplying any PIR's too, so they would stop showing any LED status if the LED's were showing previously when you walked past.

Which fuse would that be do you know?

They're labeled. The top is AUX I think. The small board on the left isn't being used. Try borrowing the fuse from it.

I see it’s the middle one, I took that out earlier and the alarm went off.

What do you mean by "went off" outside or inside siren?

If that fuse is ok, it would suggest another issue then. Like a damaged cable going to the keypad. You really need a meter to test for voltage at the keypad.
