ELk-6020 Sensor

[Doug G]

I have an ELK-6020 Sensor that “Lost Transmitter” to the M1XRTW Wireless Module. I have made sure all other sensors are fine and they work great. So I installed a new sensor out of the box and it worked for a little bit meaning it would function properly then just drop off. The old sensor works intermittently, and I have just been messing with it and they both work randomly. This is only on this Wireless Zone. What do you guys think is going on? Thank you.

So I have an update and I have been working with just the new sensor. It will work once you put the battery in, but maybe after 30 minutes the sensor just stops working no lights on the front LED and then I take the battery out a couple times and then it will start working again. It seems like it just falls off the wireless network. This all started with the “Lost Transmitter”. My firmware for the M1XRTW is at the latest version, but my Elk M1 is at 5.3.14. It has been working with no issues for several years until this sensor started acting up. Any ideas? Thank you.

Another Update:

I have tested all five of my batteries and the voltage ranges from 3.689 to the lowest one at 3.605, and the second sensor is BRAND NEW out of the box. The last sensor I think is just broken. It is a random thing. It works for “X” amount of time then just stops working. I see the green LED light no issues, but when it stops working, I have to wait “X” amount of time for it to function again by removing the battery and installing it back in the sensor. This is craziest thing I have ever seen with this system.

You have only 1 M1XRTTW (not the “M” version) Transceiver on the data bus? Are you testing the sensor at its mounting location or have you tried taking the sensor closer to the M1XRFTW? When the sensor is working as soon as you move the magnet away from the sensor does the LED turn green immediately or is there a delay?

@Brad Weeks I only have one M1XRTW transceiver and that has 12 other wireless sensors on it that work just fine for the past 10 years and I went around my house to test all of them. So I have confirmed all functionality on the M1 side with wireless transceiver works just fine.

The original sensor lost connectivity somehow with error “Lost Transmitter” so I had a spare transmitter fresh out of the box, and I have tried everything known to get this transmitter to work. I have it in my office doing testing which is less than five feet from the M1XRTW transceiver, and it will pair up and work for “X” amount of time then just stop working and no activity at all. I am using the ERP software to see the sensor activity and there is none at all after “X” amount of time. Initially when I connect it up the activity is quick and it never delays, but I will say I some of my sensors throughout the house there is some delay. Like for example I have a motion sensor that will not communicate unless I move my body to get it to communicate. Is this an issue with the Transceiver? I think I might have two different issues here then. The brand new sensor will communicate then stop working at “X” amount of time. Then my existing sensors that do work fine on occasion will have a delay. and not allow me to arm alarm until I go to investigate like open or close a window or move around in front of a motion sensor to get them out of a violated status.

@Brad Weeks I also wanted to clarify that I am running the M1XRTW and NOT the M1XRFTWM. I actually just checked out the M1XRFTWM and broke down and just bought it. I will replace the M1XRFTW with the M1XRFTWM and I know you can NOT run them at the same time on the same system. The transceiver I am running is 10 years old so I am thinking an upgrade is in order. Let me know your thoughts on my two issues anyway. Thank you!

[Brad Weeks]

Even though the battery voltage is above 3V have you tried a new fresh battery? Since the other 60xx sensors are working as expected then I don’t believe the issue is the M1XRFTW.

[Doug G]

@Brad Weeks I have tested all five of my batteries and the voltages range from 3.689 to the lowest one at 3.605. I just a new sensor in the mail and will be testing that right now.

[Doug G]

To Add I have tried all five batteries that I have. The new one paired just fine and now testing on my bench.

Update:

The new replacement sensor is working flawlessly that I got in the mail yesterday. I have never had a Brand New sensor just fail, but it works partially and then loses connection to the Transceiver. Any Ideas Brad? Thank you.

[Brad Weeks]

If your other Two-way Wireless Sensors are working and these two aren’t then I suspect you have faulty sensors. Are they over two years old?

[Doug G]

@Brad Weeks One of them was fresh out of the box and was never opened at all and the other one I am going to be honest not sure how old it is, but I am going to have to say on that one not 100% sure as I always keep one on standby, but I will be testing the next standby one I have that is ordered. Would you consider replacing both of them as a replacement? I have never warrantied anything though and just being transparent. I have replaced several of these over 10 years so not sure when I bought them.

[Doug G]

This has been resolved. Thank you.
