Ionisation or optical? The title says optical but the description says ionisation!

Must have been a cut and paste job... KF20 is optical and that was what I received. :-)

Can this alarm be connected with the KF10 already installed

Yes it can, you will need to do this be running wires to each alarm you wish to interconnect or you will need the wireless template called the RF-SFTP for each alarm then will be interconnected

Please could you tell me the diameter of the mounting plate as it will be replacing old alarms. Thanks

No sorry as I just swapped it with the same one

What is the diameter of this alarm ?

The KF20 dimensions are: Alarm Dimensions 127 x 127 x 39mm Bracket Dimensions 133 x 133 x 6mm
