Hey all-

I have been working on a 12-zone conversion from my old Ademco panel that has been inactive for years.  On zone 1 the smoke detectors are connected with a black and red wire. These are tied into multiple other 2 wire and 4 wire bundles to chain up 11 smoke detectors throughout the house. All of the smoke detectors are System Sensor 2100TS. They appear to be 2-wire smoke detectors. 

Is there any way I can power these smoke detectors without retaining my ademco panel? 

Is there anyway to convert these detectors (using the same wiring) to work with Konnected?

The detectors are surely over 10 yrs old, so I will likely replace them anyway. The question is can I replace with a similar upgraded version and keep using original wiring? The advantage being aesthetics and not having to change batteries. 

My last thought was just replacing all with battery powered first alert detectors - which will do the job but not as slick as low voltage wired detectors. 

Thanks in advance-


  • Did Lee get an answer for this question about the 2-wire smoke detectors?  I have the same question and am looking for a 2-wire smoke detector module
