Guest Posted July 29, 2009 Report Share Posted July 29, 2009 I am wanting to connect an Ei170RF to an existing EI140 system that i have in my house, can you please tell me if i need to replace all of the Ei140 alarms with Ei168/EI140's? If i do can you tell me if the wiring will be compatible or will will that also need replacing? Thanks A.B Quote Link to comment Share on other sites More sharing options...
Garry Webster Posted July 30, 2009 Report Share Posted July 30, 2009 To make the EI141 & EI144 that you have installed compatible with the EI170RF, they would need the bases to be changed to the EI168RC (Radio link base unit which transmits a radio frequency (RF) alarm signal when the smoke alarm unit attached to it is activated) so that they would all interconnect. - To change the bases the wiring to the EI141 & EI144 would have to be disconnected so that you can remove the current base and replace with the EI168RC, base. - To change the EI141/EI144 bases to the EI168RC base, there is no additional wiring required. - If the EI141/EI144 are already interconnected with wire, then you would only require one EI168RC base. - If they are not interconnected yet then you would require two EI168RC bases. We do, however recommend that you use a qualified electrician for installation. Quote Link to comment Share on other sites More sharing options...

If I buy the full product, I have to get an electrician to change it. Surely that is well over the top?! Sal Quote Link to comment Share on other sites More sharing options...

Original product but prepared for self-replacement without electrician. Takes less than five minutes. Tools and manual included Quote Link to comment Share on other sites More sharing options...
