Title: Grade F Alarms Interlinked?
Post by: Tadees on June 30, 2016, 11:40:41 AM

How can battery powered smoke alarms in a dwelling be interlinked? 

BS 5839 @ page 10 states: "In the case of Grade D, Grade E and Grade F systems, where more than one smoke alarm is installed the smoke alarms normally need to be interlinked (see 13.2). Any heat alarms also need to be interlinked with the smoke alarms."

And in the old days they were connected by lightweight twin core 'bell' wire - in fact you can still get these models although for obvious reasons radio link is now more popular.
