    Pir entrance light flashing

    Hi. My PIR entrance light flashes on and off about 4 times before turning off at the end of its time cycle. Any ideas what might be the cause/ remedy for this? It’s been installed for a couple of years and has only started doing this a few months ago. It’s bloody annoying now.
