Please help verify the wiring for a 4 wire ESL 449CT smoke detector. I have an 9 pin connector that has the following identification.
++ (power)
--(power)
[ ---] (alarm supervision)
I wrote down the wire order
1-red
2-empty
3-black
4-empty
5-green
6-white (and one leg of jumper)
7-empty
8-jumper other leg
I made the above connection and the trouble light will not reset on my 5010. Any advice?

Did you install a 5.6 k resistor in parallel with the circuit? Even if you turn off the resistor requirement for the burg zones, fire zones still require it.

Yes, the resistor is in place. I identified it as a jumper between contact point 6 and 8. the white wire shares contact point #6 with the resistor. I must correct that the pin has 8 contacts, not 9 as I said in my post. (sorry)
I disconnected the smoke detector and tried to remove the trouble light. No luck. My monitoring company wants to send a tech out for $125.00 service call. Any other ideas?
Thanks

Ok, assuming that this is the only smoke on the loop:
Using your described wire order:
"I wrote down the wire order"
1-red (= + DC power)
2-empty
3-black (= -DC power)
4-empty
The next 4 connections are where you went wrong
5-green
6-white (and one leg of jumper)
7-empty
8-jumper other leg
It should be:
5-green (to zone input common)
6-one leg of resistor
7-other leg of resistor
8-white (to zone input)
If you look at the install instruction for your smoke, it will make more sense (I know all the criss-crossing lines are visually confusing if you don't look at schematics every day)
The same diagram shows how to install a power supervision relay, if you want to install the circuit according to "hoyle".
If you don't have the install instructions go here:

Ron,
Thanks for the review. I did not remove the resistor when I disconnected the detector. The single resistor was wired as such from the original install (10 years ago). Is it possible that 6 and 8 are resistored? I set off the alarm when I tried to connect the white wire along with the resistor to #6 connection.
I found the Sentrol 4 wire diagram, but I was not able to determine the white wire placement. I apprciate your expertise. I will move the resistor to contacts #6 and #7, and connect the white wire to #8. I should have taken a picture, but the alarm was sounding on a lovely Sunday afternoon.
This is the only smoke detector on the 5010 panel.
Many thanks for your assistance.

Terminals 5 & 6 are electrically connected, Terminals 7 & 8 are electrically connected (you can check this with a continuity tester).
I can only give you the manufacturer's instructions.

Ron,
I will rewire the smoke as you indicated according to the schematic. Your knowledge and skill are greatly appreciated. Thanks for your superb guidance.
Cheers,
Christine

All,
I connected the wiring as per the advice from Ron. The trouble light went out and the system cleared. Many thanks go to Ron for his correct interpretation of the ESL Sentrol 449CT smoke detector schematics.
I have one last problem to resolve with the monitoring company. The tech from the monitoring company changed the program to remove the fire circuit and when it was restored, the telephone activation was turned on to cut off the phone when the system went through the typical arm and unarm process.
I now have the installers code changed back to the code that my original installer used. I now have access to go in and get a look at the baseline of the system. Thanks to this great resource, I am able to manage my own security and devices. I salute Ron and all the other heroes that make this site so valuable.

It's not a bug, it's a feature. It sounds like they turned on the function to monitor open (disarm) and closing (arm), so it's sending a signal (and seizing the phone line).
Normally this is an upgrade monitoring function (many central stations charge extra for the service).
