have g3 accenta and bell started screeching, and power led on keypad now flashing.
sounder screeching is panel generated - not cable damage and happens with only supply to sounder. with tamper open red led ok but when tamper closed screeching?
power led on keypad thought was service timer but unable to rectify?
has anyone else had this issue?

flashing power light norm means no mains present check fuse in spur unit,and you cant test the battery without a special meter,could also be water damage to the sab unit in bell box

hi jts

battery only year old!
flashing power light ?
screeching sounder noise very odd - not a low voltage or poor battery sound but oscillating screech

check mains feed to panel and replace the battery inside the control panel turn power off first
