Hello, my name is***** be patient whilst awaiting any responses as I'm not constantly available.The alarm can sound if the PCB in the control panel loses power, or, if a component on the PCB becomes defective causing the power to the PCB to become disconnected even though the main power has not been.
how would i know if there is a pcb fault
also there is power to the unit because i can reset it
If the alarm is not set but the alarm is still sounding... You personally can not test it.. you need an alarm engineer to do this
will get a alarm engineer out to it
