Hey All

 

 

 

I'm trying to replace a failed smoke detector, the current Detector is end of life so needed to get the latest model - https://www.aap.co.nz/shop/pirs-detectors/Smoke++Heat+Detectors/NB338-4ARB.html

 

I've it's an Arrowhead alarm Elite S Lite.

 

The current detector is wired like this:

 

 

and the wiring diagram: https://www.aap.co.nz/site/aap/files/Detectors/VST-LS881AH%20SMOKE.pdf 

 

The wiring diagram for the new detector looks like this.

 

 

When I wire up the new detector like this one of the house alarm zones detects motion all the time, and there is no voltage to the new detector (no flashing lights)

 

 

 

I note that in the old detector the EOL resistor goes between the Zone Common and Zone, but new one has them on opposite sides and not connected at all.

 

 

 

So looking for guidance on how I should look to wire up the new detector, do I ignore the wiring diagram and bridge the EOL resistor between 3+4 and 6+1? which is how the old Detector was wired?

I’d follow the instructions on the new smoke detector.

I am the worst person in the world at MS paint but if its the detector i think it is it, should be wired like this

Thanks, I've tried that approach, also with white and blue the other way around.

 

 

The zone has now stopped being activated, but the smoke detector LEDs never start flashing to indicator it's working.

 

Voltmeter confirms there is circa 13v so it's not a power issue - but would have expected the LED to flash with power alone?

 

@Feagun thanks for the images so far, very masterful with mspaint!

 

 

 

I've also tried with the black and red on the terminals per your picture, same result.

i cant remember if the LED does flash or not. make sure the little lines on the detector and base line up with each other, you would be surprised how many peoples smokes arn't working cause they dont line up.

 

Without a test button unfortunately the only way to tell if its working or not is with a can or smoke detector test or something like those lines
