Hi,
I’m trying to buy a first alert RM4 module which gives a relay output from the interconnect wire of smoke detectors, there are lists of US and Canada sellers online including eBay, but either they do not ship or the cost is horrendous, for example the part is from $11 but shipping I’ve seen on eBay up to $230!!!!
Is their a intermediary organisation which buys using a US address and then ships on?
Ironically I know the RM4 can’t be used directly due to the voltage difference, I want to open the unit to see if it can be modified or redesigned for my purpose.
Cheers
Ian
