Comfort Automation/ Security System Forums

I still have a Comfort 1 (yes, I know, time to change!).   
All of a sudden I have heard the keypad announcing \"Communication Failure 81\".  I can\'t find any reference to \"81\" in the various documents which talk about SEM, LEM etc - so I am hoping someone can shed some light on where I need to look. 
It may be related, or maybe not, but I have always had zones 1 and 5 configured to announce when they are activated.  They are both zones on the main board, of course. At the moment, I hear the announcement for zone 5, but not for zone 1. 
Any thoughts would be very welcome. 
Thanks,  
Nick

\"Communications failure 81\" . Refer to this post for the meaning of the IDs http://www.comfortforums.com/forum77/5051.html


81 is RIO or IRIO ID 1. Do you have an old RIO?

But you are right. It is time to upgrade after 20 years

Hi Chiu,
Thanks for the prompt and helpful response.  I do indeed have an old RIO, so that makes sense. I have just had a poke around with my meter and I can see 12V on JP12 which is the power coming in. But on the connector blocks, I am only seeing 0.39V between the 12V and 0V connections - so something is pulling that voltage down.
So, tomorrow (when I am properly awake) I will have a look to see whether something is shorting the RIO output. If not, then maybe what looks like it\'s a small voltage regulator on the RIO board may have died.
On your point about upgrading, do you have a recommended UK installer?
Thanks,
Nick

Ni Nick. I suggest you get in touch with Laser http://www.laser.com to find out who is available near your home

Hi, I needed to make a small change to a RIO command, I did a selective write then got an error comms failure 91, I only have four RIOs, with ID 1 to 4 but after a module scan I got an ID of 11 which was ID4 , then I performed a full write and it changed to ID10.

I restarted the system and got the functionality back of my four RIOs but I still had a comms error 91.

I did a complete power off restart of the system and now I have four RIOs ID1, 2, 3 and 11. I now have a comms error 83.

RIO supply voltages look OK and the led flashes whenever I change an input.

Ultra 2 (8.013) UCM10 (7.225) 4x RIO (20101)

Any help would be appreciated.
