Can you advise if its a simple matter of unplugging the old and replacing with new ot you do need to tell the system youve changed it. Can it wait two weeks for my return? Or as I wont be there I can get someone else to re[place it, my panel has no anti tamper on it and actually easy to access the battery.   So is it a simple matter of swapping or is there more to it.

Anyway, the keypad was showing trouble on Zone 16 - an outside gate sensor. I bypassed the zone and disabled the alarm.

Over the weekend I investigated the problem. I disconnected the zone connector and checked the loop resistance which was 2.2k with the gate closed and 6.9k with it open and I confirmed that the EOL jumper was in the correct position. Cycling the power for the alarm didn't fix it, so I tried a full write from PC -> Comfort and then COMFORT -> UCM EEPROM. This cleared the Zone Trouble alarm but I'm concerned that it may happen again. 

Any thoughts on what might have caused it?]]> . Anyway, the keypad was showing trouble on Zone 16 - an outside gate sensor. I bypassed the zone and disabled the alarm.

I could not order a new output driver board so I ordered a new LEM01B which I fitted for the first time today. So far I have plugged in the inputs but not the ouputs.

The system tells me that I have Zone Trouble on zones 9, 10 and 11.

These three zones all connect to internal doors which are used for non-alarm purposes (indicating when parts of the house are accessible to pets for example) so I do not think they were ever fitted with EOL resistors.

I am running comfigurator 4. In Zones/Inputs the EOL column says 'Use Shunts' for all zones, but the drop down menu does not allow this to be changed.

Do I now have to add EOL resistors to these zones to make them work, even though they are set to 'SwitchNC' since I cannot change the jumper settings manually? If this is the cause of the problem can I fall back to an earlier version of comfigurator that lets me change this setting?

If my guess above is wrong, is there an alternative obvious explanation for the problem I am having please? I have spent a few hours searching on this forum withou any success so far.

Thanks]]>

Can you tell me if  this plug in sub board can be ordered as a replacement and what is the official description of the module? I would have a go at replacing the 8 pin IC, but there are several other components very close to it
Many thanks  Graham

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.

My Comfort installer took a look yesterday but we couldn’t find any problems. He thinks it’s the LEM03 Local Expansion Module because the failing zone was on that board. The testing, refitting connectors, touching it, etc, seemed to ‘fix’ the problem, until a few hours later when three more zones (also on the LEM03) went into continuous trouble mode, despite Comfort being in Security Off mode as I was home.

At this point the internal and external sirens are going. If I typed in my code the sirens would stop only momentarily before picking up again. Scenes! Absolute chaos inside!! It’s hard to think with Comfort screaming at me from every source - keypad, phone, sirens, etc.

I tried to enter the engineer menu so that I could got into security test mode, hoping that would calm all the sirens. But I simply could not manage it. I’d enter my user code, then try to enter the engineer menu before the sirens kicked off again and Comfort keypad would just beep at me. I could not hear what it was saying over the noise of the sirens. It was hopeless, and I gave up trying to access the engineer menu at this point.

Eventually I got Comfigurator up - I had to sit through Windows updates, what a horrifically timed nightmare! - and was eventually able to DISable the zone inputs by changing the zone type to blank, then upload a new configuration. We’re going to change the LEM03 board next.

But my question is: how should I have handled this zone trouble situation? What can I do immediately from the keypad to calm Comfort down? So that I know how to better cope next time around.]]>
