smoke detector w built-in EOLR?

[rexwilson]

Anybody know of a 4-wire smoke with a built in end-of-line relay, but WITHOUT rate-of-rise heat detection? I've got a GE 541NCXTE, which is great, but it's in a place where rate-of-rise sensing causes false alarms. Granted, I could just get an external EOLR, but i like the elegance of having it built in. Thanks in advance for any ideas.

I would strongly recommend you get away from the built in units for multiple reasons.

The ROR is tripping? That's a 15 degree/minute rise....sounds like there's other items you should possibly investigate.

For GE and most others you add/subtract suffix letters until you get the part # needed.
 
Assuming you have other detectors to match, I'd look at a 541NCSRH. I'd suggest you NOT negate the heat detector portion as that is what helps detect flaming fires faster vs. smouldering fires.
 
You will need a separate power supervision relay, no way around it.

the 15 degree/minute rise got tripped by just the right coincidence of events, and it was kind of a fun mystery to see unfold.
The detector is in the front hallway of the house.
It was a very hot windy day.
The air conditioning was keeping the house very cool.
I kept the front door open for several minutes to carry some packages in and out of the house. A nice blast of hot air was coming into the house.
Next thing I know, I have a fire alarm, first time I've ever had a false alarm.
I've concluded that a ROR detector by the front door of an air conditioned house might not be a good idea.
