Hi team,
Thanks for your help.
I have the Ei141RC Aico smoke alarm - wired with 9V battery backup
I have 10 of them through my property - all connected on one circuit
The green lights are constantly on for all of them meaning mains power seems stable
I have recently replaced all batteries with 9V Duracell's and held down reset test button for 10 seconds after installing to reset
I have two issues
1. The red light should be flashing every minute but on the downstairs one they flash every 1 second and the upstairs one they are blinking constantly / multiple times per second. It's distracting when trying to sleep.
2. The 4 alarms on our top floor will start beeping randomly. They beep every second for 10-20 seconds then stop. Then start again a few minutes later.
Would love your help diagnosing and fixing
Rob
