Guest Rebecca Posted September 27, 2023 Report Share Posted September 27, 2023 I have two Deta 1163 smoke alarms. One is upstairs and the other one downstairs. I have changed the batteries and tested both of them and they are working. The one downstairs shows a constant green light only and the one upstairs displays a constant green light plus a flashing red light with no noise. Is it correct for them to be different as I think they are conected or is one of them not working. Quote Link to comment Share on other sites More sharing options...
green-foam Posted October 2, 2023 Report Share Posted October 2, 2023 The green light indicates there is mains present. The red LED should flash once every 30-40 seconds to indicate all is well. The red LED will flash once every 8-10 seconds if the alarm has been silenced The red LED will flash once a second (and the sounder will be operating) if the unit is in alarm condition. What happens if you press the test button? Quote Link to comment Share on other sites More sharing options...
