Texecom PE 64-W Supervision Fault

ukdiynewbie · 23 Feb 2019

Hi all,

Hi guys,

Hope you're all well.

I set my system to fully armed mode. Came back home to find a supervision fault on a micro shock sensor.

What does this mean and how do I remove them?

Thanks to @secureiam for excellent assistance with my DualTech PIR this week

Regards,
Andy

supervision fault means the device has not polled for 2 hours.

look in ricochet dignostics, for signal strength XP--> and status for battery fault.

Seems like the device is no longer showing supervision fault. Status is aaaspdtt so seems fine.

Thanks for your help!

Have you do the commissioning mode, after sorting out your devices?

ukdiynewbie · 24 Feb 2019

I have not put it into commissioning mode. I assuming this is the same as changing the jumpers to "fit for commission" mode on the main panel?

I didn't try this because it fixed itself. Should I still do it?

secureiam · 24 Feb 2019

commissioning mode is only required if there are new devices on the system.

so if you delete or add a wireless device you should do the commissioning mode to re-establish the mesh.

Once completed it should be taken out of commissioning mode.

without Ricochet monitor its best to leave it in commissioning mode for 20 minutes although it should be done in around 15 minutes.

Okay makes sense, thank you.

Although I didn't delete and add the device. The supervision fault just went automatically. But will decommission anyway.

secureiam · 24 Feb 2019

re commission the mesh?

its possible that it was never done right the first time?

secureiam · 24 Feb 2019

what was the signal strength of the contact?

ukdiynewbie · 24 Feb 2019

13>>aXP
status aaaspdtt
Msg 015 mins ago
->XP

Does that answer your question?

secureiam · 25 Feb 2019

yes a signal strength of 13 is the lowest I have ever seen.

It is highly likely that this device will be an issue regularly with such a low signal strength.

so where is it mounted relatively to the expander, also where are the nearest devices to this device.

I would normally look for a signal around 30 or better.

The main control panel is in a cupboard below the stairs. This shock sensor is on 1st floor bathroom window, near the front of the house. But still much closer than the DT-W PIR we troubleshooted in the garage.

I better check the signal strength of all shock sensors / PIRs tonight and see if it's a signal strength issue throughout or just this device. Will let you know.

ukdiynewbie · 25 Feb 2019

@secureiam So below is a list of zones and devices with their signal strengths. What is acceptable? 30+?

Im worried why my keypad in zone 09 is only 34 and the door contact right next to it in zone 11 is 100, surely that doesn't make sense - the keypad is slightly closer to the main panel.

Zone 21 Micro Shock-W is the one in the bathroom that we discussed had the supervision fault. Also, zone 15 Micro Shock-W had a supervision fault although that was over a month ago.

What may help is for you to know that my engineer threw away the 3M pads and made me buy double sided tape to stick onto my windows. This was a disaster and the Micro Shock-W and Micro Contact-W kept falling off. I spoke to Texecom and they sent me the 3M stickers again and the devices have not fallen off at all since. Could this have set off the supervision faults? Any help is much appreciated.

09 LCDLP-W 34
10 Premier Compact PW-W 100
11 Micro Contact-W 100
12 Premier Compact PW-W 100
13 Micro Contact-W 68
14 Premier Compact PW-W 100
15 Micro Shock-W 52
16 Micro Shock-W 74
17 Micro Shock-W 68
18 Micro Shock-W 56
19 Micro Shock-W 54
21 Micro Shock-W 21
22 Micro Shock-W 48
28 Dual Tech DT-W 64

alas it doesn't work like that unfortunately.

devices closest to the expander may not give the highest signal strength, its a multitude of factors, based on what lies behind the devices, and what is in between them and the expander.

for example I once conducted a test, with an incinerator bin in the back yard, signals varied significantly within 1 stride to its left or right of the large metal object, and given that the actual device was held a few feet above the incinerator it was interesting to see the difference.

the values below 30 are of the greatest concern and if the mesh is established it should bounce round if it becomes an issue.

The devices were in supervision after finding on the floor? them falling off wont have helped things as the device has moved location.

Why they didn't use the supplied pads is beyond me as once a good grip has been set its very difficult to get off.

ukdiynewbie · 26 Feb 2019

Thanks for the explanation @secureiam
Micro Shock-W on zone 15 did have a supervision fault for a few days about a month ago but again, it disappeared automatically, just like the Micro Shock-W in zone 21.
The engineer suggested the default 3M pads are useless, and for an end user who does not understand alarms (as I would imagine most end users would be at the installation stage), there is no reason for anyone to doubt the engineer, so I went ahead with it. It was a very bad installation and yes, all Micro Shock-W and Micro Contact-W kept falling off during the coldest winter days, especially as I have aluminium window frames and not the standard PVC windows. I agree the 3M pads are very good and I have not had this problem since I replaced it on all devices.

Moving forwards, I did put the main panel in "Fit for commission" mode 3-4 times last week, ranging from 15-20 mins each time, so what would you suggest - I do this again and check signal strength?
