Electronic Alarms and Home Security Devices - End Of Line Terminating Resistor, Or Module, On Older Interconnected Smoke Detectors

Hello:

For you "old timers" out there (meant as a compliment):

Did older wired-in smoke detectors that were interconnected ever use or require, an end-of-line terminating resistor ?

How about an end-of-line module, of some sort ?

Details on, if so ?

Was wondering if my interconnect problem, described in a few of my recent posts, might be that these items are hidden away somewhere on the interconnect line ?

Thanks again for all the help,
Bob

If there was a relay on one of the smokes, it's a fairly obvious object in the junction box above one of the smokes. There are a few special add on devices for some smoke detectors, but they are usually pretty obvious.

You should try describing your problem on the electrical forum (http://forum.doityourself.com/forumdisplay.php?f=9), because this is really a home 110v wiring issue.
