What are people's recommendations for main and/or battery smoke alarms?
I want them interconnectable, but the only ones I already have (Dicon, battery operated) interconnect using 2 core cable and it would seem that some mains powered interconnectable may use only one wire as a 'signal' line.
Anyone know? The ones I am looking at are ScrewFix
That said, SF's Opto and Ion detecters are different brands so may not work together. Any experience anyone?
Thanks Rob
