Just sat in my study & fire alarm started chirping the system is battery sensors with mains backup installed on 3 floors
Then all 3 started ....
then the CO detector in the boiler room which is battery only decided it wanted to play along
then the CO detector next to the living room fire felt left out and started its alarm
Checked all 3 floors no fire or smell of burning
The CO detectors are brand new & the fire jobbies (ionisation) are a year old with a shelf life of 10 years
Sunspot activity? Gamma burst? Neutron bomb?
