Hello. I have a recently installed GC3. I am intermittently getting a ‘loss of supervision receiver’ or ‘receiver loss of supervision’ error. Resetting the system makes it work for a bit (e.g. allowing the system to arm), but then the error pops up again.
The LTE radio seems to communicate well with ADC (3/6 bars), the z-wave talks to my locks and the transmitter seems to talk to my wireless sensors (I only have a firefighter sensor and glass break sensor, but they learned into the GC3 fine and the tamper sensors alerts the panel). I have the latest firmware downloaded from your site.
A ribbon cable came unseated during installation (which caused the alarm and home buttons to stop working), but after reconnecting that, those buttons worked again. I tried re-seating the cable again in case whatever ‘receiver’ is having issues was on the same cable.
Receiver Supervision would typically refer to the sensor Transceiver, which should cause the panel to not recognize when any sensors open or close. I am seeing some sensor activity though, so if that is the true error/cause itself is intermittent.
Do you have an XCVR3 connected?
How did the ribbon get pulled out? There is a receiver and antenna terminal nearby the ribbon.
When did this error start showing up?
No. I don’t have the XCVR3 connected. I have seen on the forum that there’s a sensor receiver failure error (or something to that effect). Is that different than this error?
How did the ribbon get pulled out? There is a receiver and antenna terminal nearby the ribbon.
Not entirely sure. The ribbon is a bit long and I may have got caught on the cable bringing in power and 2 hard wired sensors and popped the little ribbon clip that locks it down.
When did this error start showing up?
I’m not entirely sure. At least in the past day or 2. I was getting a couple of different errors the past couple of days because our internet was being installed and was intermittent and the radio sled wasn’t activated yet. So I kind of ignored all of the errors for a period of time.
Thank you for your help on this.
EDIT: these are the errors that I was getting over the weekend (the dates/times are all over the place b/c I hadn’t set the clock yet):
Could you post an image of the error on your panel? What we see on the back-end is simply a general “Module Malfunction” This error typically refers to the sensor transceiver.
Just to make sure, you are using the included 14VDC power supply, correct?
You say you have hardwired sensors? Are these wired directly into the panel terminal block? Or are you using a TAKE-345?
The malfunction reports seem to coincide with the door sensor rather than the two wireless sensors you mention.

Of course. See attached.

Yes, with 18awg wire.

They’re hardwired directly into the panel (zones 1 & 2 and ground). I was having an issue with the TAKE-345 that I reached out to you about earlier (I reversed the polarity of the power wires and I might have fried it) and just tabled the thing until a later date.

As noted above, the door sensors are wired directly into the panel and report activity without issue.
Thank you for the photos confirming the panel errors. The timing of the alerts with the hardwire sensor closing appears coincidental. The issue is going to be with the part in the image attached.
That is the sensor transceiver. If the nearby ribbon was pulled the transceiver may have also been dislodged, especially if the set screw is not tightened fully. Try powering the panel down completely, carefully remove the set screw to the transceiver and reseat the transceiver in place. Secure it with the screw. Then power up the panel. Does this resolve the issue?
Thank you, Jason. I just tried removing and reinserting the transceiver. The first time I booted up the GC3 after this, it gave me the same ‘loss of supervision receiver’ error. So I turned off the system again and removed and reinserted the transceiver. Since then, it seems to be working fine. I gave the system a few minutes (in the past the system would work and then the error would arise later on) and repeatedly armed and disarmed the system.
I am back at work, and the system seems to still be able to arm and disarm remotely through the app. Fingers crossed. I’ll keep you posted.
