ELK M1 Intermittent False Alarm


Best Answer flbbon4123 , 05 April 2021 - 07:11 AM

Final update.

After changing the CR2032 battery I have not had any false alarms in over 3 weeks.

My assumption at this point is the battery being weak "May" have been the culprit. But I don't have definitive proof.

 

Marking this thread as resolved.

The gaps appear to be in the normal range and shows the windows need to be open a ways before they show trip.

 

The closed closed readings are higher than the other sensors, but by such a small amount that I would not worry about that.  It may be worthwhile ensuring the wiring from the plug in transformer and the wires to the battery are secured (nothing loose, very lightly tug on them).

 

Other than that, I'm pretty much out of ideas.

 

Oh, one other thing...you are not using EOL resistors, do you have that proper setting in each zone (no EOL's installed)?  I can't remember where that is at in the Elk RP software but its somewhere in the sensor type.

BraveSirRobbin,

Really appreciate all your time and effort.

I will double check the wiring at the transformer and battery as you suggest.

 

All zones are set as "1=Normally Closed".

 

One last question:

I have the resistors that I can install. What benefit might that provide to the system?

The EOL resistors benefits for a residential installation are up for debate here on this forum.  If they are truly installed at the very end at the sensor itself, they can offer some real time monitoring of cabling issues if one were to drive a nail in the cabling, or if there was an open, or someone was trying to bypass the sensor. 

 

I authored THS post better explaining these scenarios.  Sandpiper also offered THIS thread as well.
 
Personally, I did not use EOL resistors in my or any of my friend's Elk installations in the past.  Again, this is my opinion and Spanky, Elk's Chief Engineer agreed with me at the time, you get better noise immunity as the voltage spread between open and closed is greater not using EOLs.  Again, not to spark a Ford vs Chevy type of debate here, this is just MY opinion and others will disagree here.
 
I am hoping someone with more recent Elk experience (mine is very dated) can chime in here and maybe even show a screen grab of the EOL defeat setting when setting a zone up in Elk RP (again, hope I'm remembering this correctly and not reverting back to my Caddx days).

BraveSirRobbin,

Just wanted to give you a huge shoutout for all the help, guidance and suggestions you have provided. It is really appreciated.

 

I have a much better understanding of the system and troubleshooting methodology.

 

All the best and stay safe!!

RAL and upstatemike,

 

Thanks for all your input and suggestions and taking the time to offer me some possibilities for my problem.

 

Other than realigning one of the magnets, replacing the CR2032 battery, I haven't made any changes to the system.

 

I have not had any alarms in 5 days so I am hoping this 'bug' has died!!

 

Thanks again and all the best!!

Stay safe
