ID 0 now appears on UCM list when loading a customers .cclx file

Mon, 08 Jun 2026 05:43:28 -0400

We did an upgrade to a main CPU a couple of years back using Comfig 3.14.14.0 all went well and its been fine.

I have just re-opened the file using Comfig 3.14.14.0 then gone to alter some settings. When I go to modules tab UCM - module ID 0 appears.

If I open the same file in Comfig 4.0.4.0 there is no ID 0 and the listing is by my reckoning correct.

---------------------------------------------------

We have only used Comfig 4 on new installations.

What should I do in this situation ?

I will be attending site tomorrow to replace a faulty CBUS UCM so will need to know which way o proceed

Thanks

Comfort Connectvity Issues

Thu, 12 Mar 2026 04:45:14 -0400

I am getting my comfort ready for house and we had it all renovated and extended. I have a Comfort II Ultra, version 8.013, UCM type 10 version 7.225. I also have UCMPi

I wanted to reset the system so I can start fresh for the renovated house. I tried the reset button on the main board for 15sec and I then got intermittenent connectivty with comfigurator.

Comfort Server Manager see's the UCM, has a DCHP IP address etc. I have tried host name and IP address in the settings but still very very intermittent. I have managed to write a new file (Menu File, New) and managed to write that to comfort, and eventaully managed to read that from comfort to confirm it is fresh

Using comfigurator v4.0.4.0 and this intermittent connectivty remains. Maybe sometimes it works.

I have disconnected the UCMPi from the bus to remove any conflicts with ports etc, powered on/off the comfort panel but still no joy.

I have not reset the UCM ETH03

Please can you help ? I would like to get the system setup for PIRS and door keypads, plug the UBMPi back in

If I am stuck with CAT6 cables for PIRs and Keypads and these are not shielded what problems will I get. The builder has installed CAT6 based on my plan and I completely forgot to specify shielded for some of the items

Transformer

Tue, 10 Oct 2023 14:44:20 -0400

I have a Comfort 11 system. The transformer has started humming and so I assume it is near then end of it\'s life. I am told it is the older type of transformer. I understand from my supplier (Laser Systems) that a replacement is no longer available from them. Can anybody advise where I might get a replacement?
Cheers

CM9000 Expansion Options

Mon, 09 Oct 2023 09:00:42 -0400

I have a CM9000 with a UCM/ETH03, a UCM/Pi and an LEM01 giving a total of 24 zones on it. I also have a SEM/01C mounted in SEP01/C expansion box with an LEM03 (16 Zone module).I\'m about to start a removation and I will need at least another 12 zones to cover additional windows, smoke alarms and external doors.What\'s my best option, I don\'t think I can add any more LEMs so should I get another SEM/01 or is there a better way of doing this?
Thanks!

RIO01 PSU

Tue, 23 Feb 2021 04:14:00 -0500

I will be fitting a RIO01 in an out building and would like to know if I can use an alternative PSU to power it up, Obviously it has to be 12V but what is the maximum ampere that it can accept and minimum? as it may need to be protected by an inline resetable fuse. Also can it use 12V DC as the power source as against a 12V AC power source?
Although it can possibly take the power from the main comfort panel, The main panel is not far of its maximum power output, and would rather avoid using that as a source and I cannot find any technical specs on max power input ect on the RIO01.

No Programming header to upgrade with?

Zone trouble

Sat, 15 Sep 2018 06:25:18 -0400

Hi Chiu
I have an issue with Zone 11 on my system it comes up with Zone trouble no matter what type of \"Zone Type\" is attributed to it, to stop zone trouble \"Zone Type\" has to be left blank. It reports trouble even when the contact is completly disconected from the zone (ie nothing attached). I have also changed the shunt in case of oxidisation to no avail, there is no voltage to the zone and all that has been used is a simple reed contact, this also applies to zone 12. The LEM that is installed has only recently been installed (last 6 months). All firmware is up to date and also I used the latest version of Comfigurator and I also tried using a older version of Comfigurator.
Do you have any suggestions as to what else I maybe able to try to rectify issue

End of Line Resistors

Sat, 04 Aug 2018 03:00:31 -0400

End of Line Resistors
The purpose of End Of Line (\"EOL\") Resistors for a security sensor is to allow the security system to be able to tell the difference between open and closed contacts (ie normal operation of the sensor) and open circuit and short circuit of the zone wiring (due to wiring faults or caused by someone cutting the wires).

EOL Resistor Values for Comfort
The two resistor values used in Comfort are 2.2 K ohms (red/red/red colour code) in series with the contact and 4.7K (yellow/purple/red colour code) ohms in parallel with the contact. (in older systems, 2.7K was used instead of 2.2K for the series resistor). The EOL resistors are provided in the accessories pack together with the battery leads.

Effect of Double EOL Resistors
If Double End-Of-Line Resistors are connected and the Zone wires are cut or shorted together while the security system is NOT armed, a Zone trouble Alarm is reported for the zone, which will cause the keypad to beep fast for 10 seconds, and cause the keypad LCD to display the zone with the trouble condition. If the security system is armed and the zone trouble occurs, this will cause an immediate Intruder Alarm (as it could mean that someone has cut the alarm cable).

For CM9001 Comfigurator Zone Settings selects No EOL or Double EOL for each zone. No EOL means there are no EOL resistors connected to the zone. Double EOL means there should b2 2 EOL resistors on the zone

The Old CM9000 selects EOL by jumper selection on JZ1 to JZ8 headers corresponding to each zone

Connections for No EOL Resistors are shown below. The zone shunt for each Zone JZ1, JZ2.. to JZ8 should be positioned on the 3 pin header so that it is closer to the Zone terminal block. The diagram shows 2 sensors in series. The Tamper connections are shown for PIRs and detectors. Tamper connections are usually not present for Magnetic door and window contacts.

If NO EOL is selected, Zone Trouble will not be detected. An open circuit and a short circuit on the wiring will be no different from an Open Contact or Closed Contact, and will trigger an alarm accordingly when the system is armed. Note that opening the Tamper connection has the same effect as cutting the zone wires.

Connections for Double EOL Resistors are shown below. The zone shunt for each Zone JZ1, JZ2.. to JZ8 should be positioned on the 3 pin header so that it is away from the Zone terminal block. The Tamper connections are shown for PIRs and detectors. Tamper connections are usually not present for Magnetic door and window contacts.

Wiring shock sensors ?

Thu, 28 Dec 2017 12:32:58 -0500

Sorry if this is a daft question, I think it is but as its being discussed on another forum thought I\'d best check here.
1) is there any issue with wiring up shock sensors to comfort, and can standard sensors be used ? What settings do you use ?

RS485 over Ethernet

Wed, 13 Dec 2017 09:16:37 -0500

Hi,I have a Comfort system fully installed and working really well for a number of years. I need to add another keypad to the system but cant get a direct RS485 cable to the location. I do have IP network connectivity so I have bought a pair of RS485 to IP transceivers. Can someone let me know the RS485 settings in Comfort for Baud Rate, Parity etc so that I can \"tunnel\" the RS485 over Ethernet? Thanks in advance!

How t connect TPB01

Mon, 15 May 2017 22:12:51 -0400

Hi, this seems a daft question to ask... I\'m nearing the end of my physical installation and I found a TPB01 in the box that I\'d forgotten I\'d ordered years ago. I\'ve attached a photo. Due to the types of connectors it looked as though it was designed to clip on to the main Comfort board and then clip the existing TEL-IN connector on top?

I puzzled over it though and based on tracing the PCB I concluded that would invert the two wires (and I recall having phone line issues when that initially happened at my old house - without a TPB).

So, am I just being daft - which way am I supposed to connect this, or has the pre-installed connector in the photo been put on the wrong way around at the factory? It can\'t be clipped to the main board as-is or the components would hit the metal casing.

Swapping the connector around would be problematic as the screw-terminals seem to be biting-down on the trace that is only on the bottom face of the board.

Thanks.

Siren/Bellbox Connections

Sun, 26 Jul 2015 12:32:42 -0400

The wiring diagram shows how to connect most Siren/Bellboxes to Comfort
The diagram is from the Comfort Installation Manual

SRN+ Siren (+) output has constant 12 volts to be connected to the Siren box.
SRN- Siren (-) output is normally floating, but pulled to ground to activate siren.
The Tamper terminals of the Siren/Bellbox can be connected in series with the Case tamper switches. Alternately the Siren/Bellbox tamper terminals can be connected to a spare zone input on Comfort which is programmed as a Tamper Zone Type.

If the siren/bellbox sounds softly as soon as it is connected connect a pull-up resistor (1K-ohm) placing between the SRN+ and the SRN- \'terminal. If you wish to work on the siren/bellbox connections or open the control panel, you can prevent the system from causing a tamper alarm by entering Engineer Test Mode via Eng. Menu 8,6, 1 for on. Upon deselecting this option 8,6 ,0 for Off, the system will enter Security Check Mode and will report any faults through the keypad. Tamper Alarm means the Panel Tamper or Bellbox Tamper switch or Connections are open or incorrect.
