I have three PIRs on one circuit which have been operating fine for months. Suddenly, they have started causing false alarms when in night or away mode (but not in walk test / security check mode) There's definately nothing moving in the rooms, the heating is not on, the wiring has not been changed, I've taken cover off the PIR and checked no insects are inside..... Any idea what might suddenly start this false alarm? Only thing that has changed is the bell box has been added and 2 x RIOs added to control some TWSO2s. The problem started the day I fitted the RIOs and TWSO2s.
